RabbitCore RCM3200
1. INTRODUCTION
The RCM3200 RabbitCore® module is designed to be the heart
of embedded control systems. The RCM3200 features an integrated 10/100Base-T Ethernet port and provides for LAN and
Internet-enabled systems to be built as easily as serial-communication systems.
Throughout this manual, the term RCM3200 refers to the complete series of RCM3200
RabbitCore modules unless other production models are referred to specifically.
The RCM3200 has a Rabbit® 3000 microprocessor operating at 44.2 MHz, data and program execution SRAM, flash memory, two clocks (main oscillator and timekeeping), and
the circuitry necessary for reset and management of battery backup of the Rabbit 3000’s
internal real-time clock and the data SRAM. Two 34-pin headers bring out the Rabbit
3000 I/O bus lines, parallel ports, and serial ports.
The RCM3200 receives its +3.3 V power from the customer-supplied motherboard on
which it is mounted. The RabbitCore RCM3200 can interface with all kinds of CMOScompatible digital devices through the motherboard.

1.2 Comparing the RCM3209/RCM3229 and RCM3200/RCM3220
We can no longer obtain certain components for the RCM3200/RCM3220 RabbitCore
modules that support the originally specified -40°C to +70°C temperature range. Instead of
changing the design of the RCM3200/RCM3220 RabbitCore modules to handle available
components specified for the original temperature range, we decided to develop a new
product line — the RCM3209/RCM3229 — based on the RCM3900 RabbitCore modules
that were released for the same reason.
The RCM3209/RCM3229 modules are similar in form, dimensions, and function to the
RCM3200/RCM3220 modules. We strongly recommend that existing RCM3200/RCM3220
customers and designers of new systems consider using the new RCM3209/RCM3229
RabbitCore modules.
This section compares the two lines of RabbitCore modules.
• Temperature Specifications — RCM3200/RCM3220 RabbitCore modules manufactured after May, 2008, are specified to operate at 0°C to +70°C. The RCM3209/
RCM3229, rated for -40°C to +85°C, are offered to customers requiring a larger
temperature range after May, 2008.
• Maximum Current — The RCM3200/RCM3220 draws 255 mA vs. the 325 mA
required by the RCM3209 (with Ethernet) or 190 mA (RCM3229 without Ethernet).
• LEDs — The LNK/ACT LEDs have been combined to one LED on the RCM3209, and
the RCM3209 has an FDX/COL LED where the ACT LED was on the RCM3200. The
RCM3229, like the RCM3220, has no LEDs and no Ethernet.
• Ethernet chip. A different Ethernet controller chip is used on the RCM3209. The
Ethernet chip is able to detect automatically whether a crossover cable or a straightthrough cable is being used in a particular setup, and will configure the signals on the
Ethernet jack interface. The RCM3229, like the RCM3220, has no Ethernet interface.
• Dynamic C — You may run an application developed for the RCM3200/RCM3220 on
the RCM3209/RCM3229 after you recompile it using Dynamic C v. 9.60 or later. The
new Dynamic C release incorporates many of the modules that previously had to be
purchased separately.

• Fast time to market using a fully engineered, “ready to run” microprocessor core.
• Competitive pricing when compared with the alternative of purchasing and assembling
individual components.
• Easy C-language program development and debugging
• Program Download Utility and cloning board options for rapid production loading of
programs.
• Generous memory size allows large programs with tens of thousands of lines of code,
and substantial data storage.

2. HARDWARE SETUP
This chapter describes how to set up and connect an RCM3200 series
module and the Prototyping Board included in the Development Kit.
NOTE: This chapter (and this manual) assume that you have the RCM3200 Development
Kit. If you purchased an RCM3200 series module by itself, you will have to adapt the
information in this chapter and elsewhere to your test and development setup.
2.1 Install Dynamic C
To develop and debug programs for an RCM3200 series RabbitCore module (and for all
other Rabbit hardware), you must install and use Dynamic C.
If you have not yet installed Dynamic C, do so now by inserting the Dynamic C CD from
the Development Kit in your PC’s CD-ROM drive. If autorun is enabled, the CD installation will begin automatically.
If autorun is disabled or the installation otherwise does not start, use the Windows
Start | Run menu or Windows Disk Explorer to launch setup.exe from the root folder
of the CD-ROM.
The installation program will guide you through the installation process. Most steps of the
process are self-explanatory.
Dynamic C uses a COM (serial) port to communicate with the target development system.
The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within
Dynamic C.
NOTE: The installation utility does not check the selected COM port in any way. Specifying a port in use by another device (mouse, modem, etc.) may lead to a message such
as "could not open serial port" when Dynamic C is started.
Once your installation is complete, you will have up to three icons on your PC desktop.
One icon is for Dynamic C, one opens the documentation menu, and the third is for the
Rabbit Field Utility, a tool used to download precompiled software to a target system.
If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it
after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the
same directory where Dynamic C was installed.

2.2 Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Attach the RCM3200 series RabbitCore module to the Prototyping Board.
2. Connect the programming cable between the RCM3200 series RabbitCore module and
the workstation PC.
3. Connect the power supply to the Prototyping Board.

2.2.1 Step 1 — Attach Module to Prototyping Board
Turn the RCM3200 series module so that the Ethernet jack extends off the Prototyping
Board, as shown in Figure 2 below. Align the pins from the headers on the bottom side of
the module into header sockets RCM2JA and RCM2JB on the Prototyping Board (these
sockets were labeled J12 and J13 on earlier versions of the Prototyping Board).

Figure 2. Install the RCM3200 Series Module on the Prototyping Board
Although you can install a single module into either the MASTER or the SLAVE position
on the Prototyping Board, all the Prototyping Board features (switches, LEDs, serial port
drivers, etc.) are connected to the MASTER position — install a single module in the
MASTER position.
NOTE: It is important that you line up the pins from the headers on the bottom side of the
RCM3200 module exactly with the corresponding pins of header sockets RCM2JA and
RCM2JB on the Prototyping Board. The header pins may become bent or damaged if
the pin alignment is offset, and the module will not work. Permanent electrical damage
to the module may also result if a misaligned module is powered up.
Press the module’s pins firmly into the Prototyping Board header sockets—press down in
the area above the header pins using your thumbs or fingers over the connectors as shown
in Figure 2. Do not press down on the middle of the RCM3200 series module to avoid
flexing the module, which could damage the module or the components on the module.
Should you need to remove the RCM3200 module, grasp it with your fingers along the sides
by the connectors and gently work the module up to pull the pins away from the sockets
where they are installed. Do not remove the module by grasping it at the top and bottom.

2.2.2 Step 2 — Connect Programming Cable
The programming cable connects the RCM3200 to the PC running Dynamic C to download programs and to monitor the RCM3200 module during debugging.
2.2.2.1 RCM3209 and RCM3229
Connect the 10-pin connector of the programming cable labeled PROG to header J1 on
the RCM3209/RCM3229 module as shown in Figure 3(a). Be sure to orient the marked
(usually red) edge of the cable towards pin 1 of the connector. (Do not use the DIAG
connector, which is used for a normal serial connection.)

Figure 3(b). Connect Programming Cable to RCM3200
NOTE: Be sure to use the serial programming cable (part number 101-0542)—the programming cable has blue shrink wrap around the RS-232 converter section located in
the middle of the cable. The USB programming cable and programming cables with red
or clear shrink wrap from other Rabbit kits are not designed to work with
RCM3200/RCM3220 modules.
Connect the other end of the programming cable to a COM port on your PC.
NOTE: It may be possible to use an RS-232/USB converter with the serial programming
described in this section. An RS-232/USB converter (part number 20-151-0178) is
available through the Web store. Note that not all RS-232/USB converters work with
Dynamic C.

2.2.3 Step 3 — Connect Power
When all other connections have been made, you can connect power to the Prototyping
Board.
If you have the universal power supply, prepare the AC adapter for the country where it
will be used by selecting the plug. The RCM3200 Development Kit presently includes
Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs. Snap in the top of the
plug assembly into the slot at the top of the AC adapter as shown in Figure 4, then press
down on the spring-loaded clip below the plug assembly to allow the plug assembly to
click into place.
Connect the 3-pin connector from the AC adapter to header J9 on the Prototyping Board as
shown in Figure 4 below. A plug-type jack is available at J11 for other AC adapters.

2.3 Starting Dynamic C
NOTE: Dynamic C v. 9.60 or a later version is required if you are using an RCM3209 or
an RCM3229 RabbitCore module.
Once the RCM3200 is connected as described in the preceding pages, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your Start menu. Select
Code and BIOS in Flash, Run in RAM on the “Compiler” tab in the Dynamic C Options
> Project Options menu. Click OK.
If you are using a USB port to connect your computer to the RCM3200 module, choose
Options > Project Options and select “Use USB to Serial Converter” under the
Communications tab. Click OK.
2.4 Run a Sample Program
Use the File menu to open the sample program PONG.C, which is in the Dynamic C
SAMPLES folder. Press function key F9 to compile and run the program. The STDIO
window will open on your PC and will display a small square bouncing around in a box.
This program shows that the CPU is working. The sample program described in
Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.
2.4.1 Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor
Detected."):
• Check that the RCM3200 is powered correctly — the red power lamp on the Prototyping
Board should be lit when the RCM3200 is mounted on the Prototyping Board and the AC
adapter is plugged in.
• Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the PROG connector, not the DIAG connector, is plugged in to the programming port on the RCM3200 with the marked (colored) edge of the programming cable
towards pin 1 of the programming header.
• Ensure that the RCM3200 module is firmly and correctly installed in its connectors on
the Prototyping Board.
• Dynamic C uses the COM port or USB port specified during installation. Select a different COM port within Dynamic C. From the Options menu, select Project Options,
then select Communications. Select another COM port from the list, then click OK.
Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. If Dynamic C still reports it
is unable to locate the target system, repeat the above steps until you locate the COM
port used by the programming cable.
• If you get an error message when you plugged the programming cable into a USB port,
you will have to install USB drivers. Drivers for Windows XP are available in the
Dynamic C Drivers\Rabbit USB Programming Cable\WinXP_2K folder —
double-click DPInst.exe to install the USB drivers. Drivers for other operating systems are available online at www.ftdichip.com/Drivers/VCP.htm.
16
RabbitCore RCM3200
If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load the sample program, it is possible that
your PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Select a slower Max download baud rate.
If a program compiles and loads, but then loses target communication before you can
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Choose a lower debug baud rate.
2.5 Where Do I Go From Here?
If the sample program ran fine, you are now ready to go on to other sample programs and to
develop your own applications. The source code for the sample programs is provided to allow
you to modify them for your own use. The RCM3200 User’s Manual also provides
complete hardware reference information and describes the software function calls for the
RCM3200 and the RCM3220, the Prototyping Board, and the optional LCD/keypad module.
The RCM3209/RCM3229 User’s Manual also provides complete hardware reference information and describes the software function calls for the RCM3209 and the RCM3229, the
Prototyping Board, and the optional LCD/keypad module.
For advanced development topics, refer to the Dynamic C User’s Manual and the
Dynamic C TCP/IP User’s Manual, also in the online documentation set.

RabbitCore RCM3200
3. RUNNING SAMPLE PROGRAMS
To develop and debug programs for the RCM3200 (and for all
other Rabbit hardware), you must install and use Dynamic C.
3.1 Introduction
To help familiarize you with the RCM3200 modules, Dynamic C includes several sample
programs. Loading, executing and studying these programs will give you a solid hands-on
overview of the RCM3200’s capabilities, as well as a quick start using Dynamic C as an
application development tool.
NOTE: The sample programs assume that you have at least an elementary grasp of the C
programming language. If you do not, see the introductory pages of the Dynamic C
User’s Manual for a suggested reading list.
Complete information on Dynamic C is provided in the Dynamic C User’s Manual.
In order to run the sample programs discussed in this chapter and elsewhere in this manual,
1. Your RCM3200 module must be plugged in to the Prototyping Board as described in
Chapter 2, “Hardware Setup.”
2. Dynamic C must be installed and running on your PC.
3. The RCM3200 module must be connected to your PC through the serial programming
cable.
4. Power must be applied to the RCM3200 through the Prototyping Board.
Refer to Chapter 2, “Hardware Setup,” if you need further information on these steps.
If you are using an RCM3200 or RCM3220, remember to allow the compiler to run the
application in the program execution SRAM by selecting Code and BIOS in Flash, Run
in RAM from the Dynamic C Options > Project Options > Compiler menu.
To run a sample program, open it with the File menu, then press function key F9 to compile and run the program.
Complete information on Dynamic C is provided in the Dynamic C User’s Manual.
User’s Manual

3.2 Sample Programs
Of the many sample programs included with Dynamic C, several are specific to the
RCM3200. Sample programs illustrating the general operation of the RCM3200, and
serial communication are provided in the SAMPLES\RCM3200 folder. Each sample program has comments that describe the purpose and function of the program. Follow the
instructions at the beginning of the sample program.
• CONTROLLED.C—uses the STDIO window to demonstrate digital outputs by toggling
LEDs DS1 and DS2 on the Prototyping Board on and off.
Parallel Port G bit 6 = LED DS1
Parallel Port G bit 7 = LED DS2
Once you have compiled and run this program, you will be prompted via the Dynamic
C STDIO window to select LED DS1 or DS2. Use your PC keyboard to make your
selection.
Once you have selected the LED, you will be prompted to select to turn the LED either
ON or OFF. A logic low will light up the LED you selected.
• FLASHLED1.c—demonstrates the use of costatements to flash LEDs DS1 and DS2 on
the Prototyping Board at different rates. Once you have compiled and run this program,
LEDs DS1 and DS2 will flash on/off at different rates.
• FLASHLED2.c—demonstrates the use of cofunctions and costatements to flash LEDs
DS1 and DS2 on the Prototyping Board at different rates. Once you have compiled and
run this program, LEDs DS1 and DS2 will flash on/off at different rates.
• TOGGLESWITCH.c—demonstrates the use of costatements to detect switches using the
press-and-release method of debouncing. LEDs DS1 and DS2 on the Prototyping
Board are turned on and off when you press switches S2 and S3.
• IR_DEMO.c—Demonstrates sending Modbus ASCII packets between two Prototyping
Board assemblies via the IrDA transceivers with the IrDA transceivers facing each other.
Note that this sample program will only work with the RCM30/31/32XX Prototyping
Board.
First, compile and run this program on one Prototyping Board assembly, then remove
the programming cable and press the RESET button on the Prototyping Board so that
the first RabbitCore module is operating in the Run mode. Then connect the programming cable to the second Prototyping Board assembly with the RCM3200 and compile
and run the same sample program. With the programming cable still connected to the
second Prototyping Board assembly, press switch S2 on the second Prototyping Board
to transmit a packet. Once the first Prototyping Board assembly receives a test packet, it
will send back a response packet that will be displayed in the Dynamic C STDIO window. The test packets and response packets have different codes.
Once you have loaded and executed these five programs and have an understanding of
how Dynamic C and the RCM3200 modules interact, you can move on and try the other
sample programs, or begin building your own.

RabbitCore RCM3200
3.2.1 Serial Communication
The following sample programs can be found in the SAMPLES\RCM3200\SERIAL folder.
• FLOWCONTROL.C—This program demonstrates hardware flow control by configuring
Serial Port C (PC3/PC2) for CTS/RTS with serial data coming from TxB at 115,200 bps.
One character at a time is received and is displayed in the STDIO window.
To set up the Prototyping Board, you will need to tie TxB and RxB
together on the RS-232 header at J5, and you will also tie TxC and
RxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
RxC TxC
J5
TxB RxB GND
A repeating triangular pattern should print out in the STDIO window.
The program will periodically switch flow control on or off to demonstrate the effect of
no flow control.
• PARITY.C—This program demonstrates the use of parity modes by
repeatedly sending byte values 0–127 from Serial Port B to Serial Port
C. The program will switch between generating parity or not on Serial
Port B. Serial Port C will always be checking parity, so parity errors
should occur during every other sequence.
RxC TxC
J5
TxB RxB GND
To set up the Prototyping Board, you will need to tie TxB and RxC together on the
RS-232 header at J5 using the jumpers supplied in the Development Kit as shown in the
diagram.
The Dynamic C STDIO window will display the error sequence.
• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial
communication. Lower case characters are sent by TxC, and are
received by RxB. The characters are converted to upper case and are
sent out by TxB, are received by RxC, and are displayed in the
Dynamic C STDIO window.
RxC TxC
J5
TxB RxB GND
To set up the Prototyping Board, you will need to tie TxB and RxC together on the
RS-232 header at J5, and you will also tie RxB and TxC together using the jumpers
supplied in the Development Kit as shown in the diagram.
• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication
with flow control on Serial Port C and data flow on Serial Port B.
To set up the Prototyping Board, you will need to tie TxB and RxB
together on the RS-232 header at J5, and you will also tie TxC and
RxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
RxC TxC
J5
TxB RxB GND
Once you have compiled and run this program, you can test flow control by disconnecting TxC from RxC while the program is running. Characters will no
longer appear in the STDIO window, and will display again once TxC is connected
back to RxC.
User’s Manual
21
• SWITCHCHAR.C—This program demonstrates transmitting and then receiving an
ASCII string on Serial Ports B and C. It also displays the serial data received from both
ports in the STDIO window.
To set up the Prototyping Board, you will need to tie TxB and RxC
together on the RS-232 header at J5, and you will also tie RxB and
TxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
RxC TxC
J5
TxB RxB GND
Once you have compiled and run this program, press and release S2
and S3 on the Prototyping Board. The data sent between the serial ports will be displayed in the STDIO window.
Two sample programs,
SIMPLE485MASTER.C and
SIMPLE485SLAVE.C, are available to
illustrate RS-485 master/slave communication. To run these sample programs, you will need a second Rabbitbased system with RS-485, and you
will also have to add an RS-485 transceiver such as the SP483E and bias
resistors to the RCM30/31/32XX
Prototyping Board.

The diagram shows the connections. You will have to connect PC0 and PC1 (Serial Port D)
on the RCM30/31/32XX Prototyping Board to the RS-485 transceiver, and you will connect PD4 to the RS-485 transceiver to enable or disable the RS-485 transmitter.
The RS-485 connections between the slave and master devices are as follows.
•
RS485+ to RS485+
•
RS485– to RS485–
•

• SIMPLE485MASTER.C—This program demonstrates a simple RS-485 transmission of
lower case letters to a slave RCM3200. The slave will send back converted upper case
letters back to the master RCM3200 and display them in the STDIO window. Use
SIMPLE485SLAVE.C to program the slave RCM3200.
• SIMPLE485SLAVE.C—This program demonstrates a simple RS-485 transmission of
lower case letters to a master RCM3200. The slave will send back converted upper case
letters back to the master RCM3200 and display them in the STDIO window. Use
SIMPLE485MASTER.C to program the master RCM3200.

Notes
1. When using pins 33–34 on header J1 to drive LEDs, you must use an external buffer to
drive these external LEDs. These pins are not connected on the RCM3220, which does
not have the LEDs installed.
2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about
1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops
below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this voltage if you draw any current from this pin.
Locations R45, R46, R53, R57, and R74 allow the population of 0 Ω resistors (jumpers)
that will be used to enable future options. These locations are currently unused.

RabbitCore RCM3200
4.1.1 Memory I/O Interface
The Rabbit 3000 address lines (A0–A19) and all the data lines (D0–D7) are routed internally to the onboard flash memory and SRAM chips. I/0 write (/IOWR) and I/0 read
(/IORD) are available for interfacing to external devices.
Parallel Port A can also be used as an external I/O data bus to isolate external I/O from the
main data bus. Parallel Port B pins PB2–PB7 can also be used as an auxiliary address bus.
When using the external I/O bus, you must add the following line at the beginning of your
program.
#define PORTA_AUX_IO
// required to enable external I/O bus
The STATUS output has three different programmable functions:
3. It can be driven low on the first op code fetch cycle.
4. It can be driven low during an interrupt acknowledge cycle.
5. It can also serve as a general-purpose output.
4.1.2 Other Inputs and Outputs
Two status mode pins, SMODE0 and SMODE1, are available as inputs. The logic state of
these two pins determines the startup procedure after a reset.
/RESET_IN is an external input used to reset the Rabbit 3000 microprocessor and the
RCM3200 memory. /RES is an output from the reset circuitry that can be used to reset
other peripheral devices.
4.1.3 5 V Tolerant Inputs
The RCM3200 operates over a voltage from 3.15 V to 3.45 V, but most RCM3200 input
pins, except /RESET_IN, VRAM, VBAT_EXT, and the power-supply pins, are 5 V tolerant. When a 5 V signal is applied to 5 V tolerant pins, they present a high impedance even if
the Rabbit power is off. The 5 V tolerant feature allows 5 V devices that have a suitable
switching threshold to be connected directly to the RCM3200. This includes HCT family
parts operated at 5 V that have an input threshold between 0.8 and 2 V.
NOTE: CMOS devices operated at 5 V that have a threshold at 2.5 V are not suitable for
direct connection because the Rabbit 3000 outputs do not rise above VDD, and is often
specified as 3.3 V. Although a CMOS input with a 2.5 V threshold may switch at 3.3 V,
it will consume excessive current and switch slowly.
In order to translate between 5 V and 3.3 V, HCT family parts powered from 5 V can be
used, and are often the best solution. There is also the “LVT” family of parts that operate
from 2.0 V to 3.3 V, but that have 5 V tolerant inputs and are available from many suppliers. True level-translating parts are available with separate 3.3 V and 5 V supply pins, but
these parts are not usually needed, and have design traps involving power sequencing.

4.2 Serial Communication
The RCM3200 board does not have an RS-232 or an RS-485 transceiver directly on the
board. However, an RS-232 or RS-485 interface may be incorporated on the board the
RCM3200 is mounted on. For example, the Prototyping Board has a standard RS-232
transceiver chip.
4.2.1 Serial Ports
There are six serial ports designated as Serial Ports A, B, C, D, E, and F. All six serial
ports can operate in an asynchronous mode up to the baud rate of the system clock divided
by 8. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where
an additional bit is sent to mark the first byte of a message, is also supported. Serial Ports
A, B, C, and D can also be operated in the clocked serial mode. In this mode, a clock line
synchronously clocks the data in or out. Either of the two communicating devices can supply the clock. When the Rabbit 3000 provides the clock, the baud rate can be up to 80% of
the system clock frequency divided by 128, or 276,250 bps for a 44.2 MHz clock speed.
Serial Ports E and F can also be configured as SDLC/HDLC serial ports. The IrDA protocol is also supported in SDLC format by these two ports.
Serial Port A is available only on the programming port.

4.2.3 Serial Programming Port
The RCM3200 serial programming port is accessed using header J3 or over an Ethernet
connection via the RabbitLink EG2110. The programming port uses the Rabbit 3000’s
Serial Port A for communication. Dynamic C uses the programming port to download and
debug programs.
The programming port is also used for the following operations.
• Cold-boot the Rabbit 3000 on the RCM3200 after a reset.
• Remotely download and debug a program over an Ethernet connection using the
RabbitLink EG2110.
• Fast copy designated portions of flash memory from one Rabbit-based board (the
master) to another (the slave) using the Rabbit Cloning Board.
In addition to Serial Port A, the Rabbit 3000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the programming port.
The two startup mode pins determine what happens after a reset—the Rabbit 3000 is
either cold-booted or the program begins executing at address 0x0000.
The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is
present. The status output has three different programmable functions:
1. It can be driven low on the first op code fetch cycle.
2. It can be driven low during an interrupt acknowledge cycle.
3. It can also serve as a general-purpose CMOS output.
The /RESET_IN pin is an external input that is used to reset the Rabbit 3000 and the
RCM3200/RCM3220 onboard peripheral circuits. The serial programming port can be
used to force a hard reset on the RCM3200/RCM3220 by asserting the /RESET_IN signal.
Alternate Uses of the Serial Programming Port
All three clocked Serial Port A signals are available as
• a synchronous serial port
• an asynchronous serial port, with the clock line usable as a general CMOS I/O pin
The programming port may also be used as a serial port once the application is running.
The SMODE pins may then be used as inputs and the status pin may be used as an output.
Refer to the Rabbit 3000 Microprocessor User’s Manual for more information.

RabbitCore RCM3200
4.3 Serial Programming Cable
The programming cable is used to connect the serial programming port of the RCM3200
to a PC serial COM port. The programming cable converts the RS-232 voltage levels used
by the PC serial port to the CMOS voltage levels used by the Rabbit 3000.
When the PROG connector on the programming cable is connected to the RCM3200
serial programming port at header J3, programs can be downloaded and debugged over the
serial interface.
The DIAG connector of the programming cable may be used on header J3 of the RCM3200
with the RCM3200 operating in the Run Mode. This allows the programming port to be
used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The RCM3200 is automatically in Program Mode when the PROG connector on the programming cable is attached, and is automatically in Run Mode when no programming
cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the
state of the SMODE pins. When the programming cable’s PROG connector is attached,
the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the
programming cable’s PROG connector is not attached, the SMODE pins are pulled low,
causing the Rabbit 3000 to operate in the Run Mode.

Refer to the Rabbit 3000 Microprocessor User’s Manual for more information on the programming port.
4.3.2 Standalone Operation of the RCM3200
The RCM3200 must be programmed via the Prototyping Board or via a similar arrangement on a customer-supplied board. Once the RCM3200 has been programmed successfully, remove the serial programming cable from the programming connector and reset the
RCM3200. The RCM3200 may be reset by cycling the power off/on or by pressing the
RESET button on the Prototyping Board. The RCM3200 module may now be removed
from the Prototyping Board for end-use installation.
CAUTION: Disconnect power to the Prototyping Board or other boards when removing
or installing your RCM3200 module to protect against inadvertent shorts across the
pins or damage to the RCM3200 if the pins are not plugged in correctly. Do not reapply
power until you have verified that the RCM3200 module is plugged in correctly.
34
RabbitCore RCM3200
4.4 Other Hardware
4.4.1 Clock Doubler
The RCM3200 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler.
A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 44.2 MHz frequency specified for the RCM3200 and the RCM3220 is generated using a 22.12 MHz resonator.
The clock doubler may be disabled if 44.2 MHz clock speeds are not required. Disabling
the Rabbit 3000 microprocessor’s internal clock doubler will reduce power consumption
and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler.
The clock doubler is enabled by default, and usually no entry is needed. If you need to
specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to
always enable the clock doubler.
3. Click OK to save the macro. The clock doubler will now remain off whenever you are
in the project file where you defined the macro.
4.4.2 Spectrum Spreader
The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. By
default, the spectrum spreader is on automatically, but it may also be turned off or set to a
stronger setting. The means for doing so is through a simple configuration macro as shown
below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Normal spreading is the default, and usually no entry is needed. If you need to specify
normal spreading, add the line
ENABLE_SPREADER=1
For strong spreading, add the line
ENABLE_SPREADER=2
To disable the spectrum spreader, add the line
ENABLE_SPREADER=0
NOTE: The strong spectrum-spreading setting is unnecessary for the RCM3200.
3. Click OK to save the macro. The spectrum spreader will now be set to the state specified
by the macro value whenever you are in the project file where you defined the macro.
NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information
on the spectrum-spreading setting and the maximum clock speed.
User’s Manual

4.5 Memory
4.5.1 SRAM
The RCM3200 and the RCM3220 have 512K of program execution SRAM installed at U8.
The RCM3200 and RCM3220 data SRAM installed at U6 is 256K, and the RCM3210 has
128K data SRAM installed at U6..
4.5.2 Flash EPROM
The RCM3200 is also designed to accept 256K to 512K of flash EPROM at U7.
NOTE: Rabbit recommends that any customer applications should not be constrained by
the sector size of the flash EPROM since it may be necessary to change the sector size
in the future.
Writing to arbitrary flash memory addresses at run time is also discouraged. Instead,
define a “user block” area to store persistent data. The functions writeUserBlock()
and readUserBlock() are provided for this. Refer to the Rabbit 3000 Microprocessor
Designer’s Handbook and the Dynamic C Function Reference Manual for additional information.
A Flash Memory Bank Select jumper configuration option based on 0 Ω surface-mounted
resistors exists at header JP4 on the RCM3200 RabbitCore modules. This option, used in
conjunction with some configuration macros, allows Dynamic C to compile two different
co-resident programs for the upper and lower halves of a 256K flash in such a way that both
programs start at logical address 0000. This option is not relevant to the RCM3200 RabbitCore modules, which use 512K flash memories.
4.5.3 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.

RabbitCore RCM3200
5. SOFTWARE REFERENCE
Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with Rabbit controllers and other controllers
based on the Rabbit microprocessor. Chapter 4 provides the
libraries and function calls related to the RCM3200.
5.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. It is specially designed for programming embedded systems, and features quick compile and interactive debugging in the real
environment. A complete reference guide to Dynamic C is contained in the Dynamic C
User’s Manual.
You have a choice of doing your software development in the flash memory or in the data
SRAM included on the RCM3200. The flash memory and SRAM options are selected
with the Options > Project Options > Compiler menu.
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
NOTE: An application should be run from the program execution SRAM after the programming cable is disconnected. Your final code must always be stored in flash memory
for reliable operation. For RCM3200 modules running at 44.2 MHz, which have a fast
program execution SRAM that is not battery-backed, you should select Code and
BIOS in Flash, Run in RAM from the Dynamic C Options > Project Options >
Compiler menu to store the code in flash and copy it to the fast program execution
SRAM at run-time to take advantage of the faster clock speed. This option optimizes
the performance of RCM3200 modules running at 44.2 MHz.
NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of
the flash memory market, the RCM3200 and Dynamic C were designed to accommodate flash devices with various sector sizes.
Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows 2000 and
later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®,
User’s Manual
37
for additional information if you are using a Dynamic C release prior to v. 9.60 under
Windows Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the
program compiles.
Dynamic C has a number of standard features.
• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.
• Royalty-free TCP/IP stack with source code and most common protocols.
• Hundreds of functions in source-code libraries and sample programs:
X Exceptionally fast support for floating-point arithmetic and transcendental functions.
X RS-232 and RS-485 serial communication.
X Analog and digital I/O drivers.
X I2C, SPI, GPS, file system.
X LCD display and keypad drivers.
• Powerful language extensions for cooperative or preemptive multitasking
• Loader utility program to load binary images into Rabbit targets in the absence of
Dynamic C.
• Provision for customers to create their own source code libraries and augment on-line
help by creating “function description” block comments using a special format for
library functions.
• Standard debugging features:
X Breakpoints—Set breakpoints that can disable interrupts.
X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware.
X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and
machine cycle times. Switch between debugging at machine-code level and source-code level by
simply opening or closing the disassembly window.
X Watch expressions—Watch expressions are compiled when defined, so complex expressions
including function calls may be placed into watch expressions. Watch expressions can be updated
with or without stopping program execution.
X Register window—All processor registers and flags are displayed. The contents of general registers
may be modified in the window by the user.
X Stack window—shows the contents of the top of the stack.
X Hex memory dump—displays the contents of memory at any address.
X STDIO window—printf outputs to this window and keyboard input on the host PC can be
detected for debugging purposes. printf output may also be sent to a serial port or file.

RabbitCore RCM3200
5.2 Dynamic C Function Calls
5.2.1 Digital I/O
The RCM3200 was designed to interface with other systems, and so there are no drivers
written specifically for the I/O. The general Dynamic C read and write functions allow
you to customize the parallel I/O to meet your specific needs. For example, use
WrPortI(PEDDR, &PEDDRShadow, 0x00);
to set all the Port E bits as inputs, or use
WrPortI(PEDDR, &PEDDRShadow, 0xFF);
to set all the Port E bits as outputs.
When using the external I/O bus on the Rabbit 3000 chip, add the line
#define PORTA_AUX_IO
// required to enable external I/O bus
to the beginning of any programs using the external I/O bus.
The sample programs in the Dynamic C SAMPLES/RCM3200 directory provide further
examples.
5.2.2 SRAM Use
The RCM3200 has a battery-backed data SRAM and a program-execution SRAM.
Dynamic C provides the protected keyword to identify variables that are to be placed
into the battery-backed SRAM. The compiler generates code that creates a backup copy of
a protected variable before the variable is modified. If the system resets while the protected
variable is being modified, the variable's value can be restored when the system restarts.
The sample code below shows how a protected variable is defined and how its value can
be restored.
protected nf_device nandFlash;
int main() {
...
_sysIsSoftReset();
// restore any protected variables
The bbram keyword may also be used instead if there is a need to store a variable in battery-backed SRAM without affecting the performance of the application program. Data
integrity is not assured when a reset or power failure occurs during the update process.
Additional information on bbram and protected variables is available in the Dynamic C
User’s Manual.
User’s Manual
39
5.2.3 Serial Communication Drivers
Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The
PACKET.LIB library provides packet-based serial functions where packets can be delimited by the 9th bit, by transmission gaps, or with user-defined special characters. Both
libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they
are finished. For more information, see the Dynamic C Function Reference Manual and
Technical Note 213, Rabbit 2000 Serial Port Software.
5.2.4 TCP/IP Drivers
The TCP/IP drivers are located in the TCPIP directory.
Complete information on these libraries and the TCP/IP functions is provided in the
Dynamic C TCP/IP User’s Manual.
5.2.5 Prototyping Board Function Calls
The functions described in this section are for use with the Prototyping Board features.
The source code is in the RCM32xx.LIB library in the Dynamic C SAMPLES\RCM3200
folder if you need to modify it for your own board design.
Other generic functions applicable to all devices based on Rabbit microprocessors are
described in the Dynamic C Function Reference Manual.

5.3 Upgrading Dynamic C
Dynamic C patches that focus on bug fixes are available from time to time. Check the Web
site www.rabbit.com/support/ for the latest patches, workarounds, and bug fixes.
The default installation of a patch or bug fix is to install the file in a directory (folder) different from that of the original Dynamic C installation. Rabbit recommends using a different directory so that you can verify the operation of the patch without overwriting the
existing Dynamic C installation. If you have made any changes to the BIOS or to libraries,
or if you have programs in the old directory (folder), make these same changes to the
BIOS or libraries in the new directory containing the patch. Do not simply copy over an
entire file since you may overwrite a bug fix; of course, you may copy over any programs
you have written.
5.3.1 Extras
Dynamic C installations are designed for use with the board they are included with, and
are included at no charge as part of our low-cost kits.
Starting with Dynamic C version 9.60, Dynamic C includes the popular µC/OS-II realtime operating system, point-to-point protocol (PPP), FAT file system, RabbitWeb, and
other select libraries. Rabbit also offers for purchase the Rabbit Embedded Security Pack
featuring the Secure Sockets Layer (SSL) and a specific Advanced Encryption Standard
(AES) library.
In addition to the Web-based technical support included at no extra charge, a one-year
telephone-based technical support subscription is also available for purchase.

6. USING THE TCP/IP FEATURES
6.1 TCP/IP Connections
Programming and development can be done with the RCM3200 RabbitCore modules
without connecting the Ethernet port to a network. However, if you will be running the
sample programs that use the Ethernet capability or will be doing Ethernet-enabled development, you should connect the RCM3200 module’s Ethernet port at this time.
Before proceeding you will need to have the following items.
• If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card
(available from your favorite computer supplier) installed in a PC.
• Two RJ-45 straight through Ethernet cables and a hub, or an RJ-45 crossover Ethernet
cable.
The Ethernet cables and a 10Base-T Ethernet hub are available from Rabbit in a TCP/IP
tool kit. More information is available at www.rabbit.com.
NOTE: Although 10Base-T is the minimum required, 10/100Base-T or 100Base-T is
recommended to allow you to work with the full speed capabilities of the RCM3200.
1. Connect the AC adapter and the programming cable as shown in Section 2.2.2, “Step 2
— Connect Programming Cable.”
2. Ethernet Connections
There are four options for connecting the RCM3200 module to a network for development and runtime purposes. The first two options permit total freedom of action in
selecting network addresses and use of the “network,” as no action can interfere with
other users. We recommend one of these options for initial development.
• No LAN — The simplest alternative for desktop development. Connect the
RCM3200’s Ethernet port directly to the PC’s network interface card using an RJ-45
crossover cable. A crossover cable is a special cable that flips some connections
between the two connectors and permits direct connection of two client systems. A
standard RJ-45 network cable will not work for this purpose.
• Micro-LAN — Another simple alternative for desktop development. Use a small Ethernet 10Base-T hub and connect both the PC’s network interface card and the
RCM3200’s Ethernet port to it, using standard network cables.
User’s Manual
43
The following options require more care in address selection and testing actions, as
conflicts with other users, servers and systems can occur:
• LAN — Connect the RCM3200’s Ethernet port to an existing LAN, preferably one to
which the development PC is already connected. You will need to obtain IP addressing
information from your network administrator.
• WAN — The RCM3200 is capable of direct connection to the Internet and other Wide
Area Networks, but exceptional care should be used with IP address settings and all
network-related programming and development. We recommend that development and
debugging be done on a local network before connecting a RabbitCore system to the
Internet.
TIP: Checking and debugging the initial setup on a micro-LAN is recommended before
connecting the system to a LAN or WAN.
The PC running Dynamic C through the serial port on the RCM3200 does not need to
be the PC with the Ethernet card.
3. Apply Power
Plug in the AC adapter. The RCM3200 module is now ready to be used.

RabbitCore RCM3200
6.2 TCP/IP Primer on IP Addresses
Obtaining IP addresses to interact over an existing, operating, network can involve a number of complications, and must usually be done with cooperation from your ISP and/or
network systems administrator. For this reason, it is suggested that the user begin instead
by using a direct connection between a PC and the RCM3200 board using an Ethernet
crossover cable or a simple arrangement with a hub. (A crossover cable should not be confused with regular straight through cables.)
In order to set up this direct connection, the user will have to use a PC without networking,
or disconnect a PC from the corporate network, or install a second Ethernet adapter and set
up a separate private network attached to the second Ethernet adapter. Disconnecting your
PC from the corporate network may be easy or nearly impossible, depending on how it is
set up. If your PC boots from the network or is dependent on the network for some or all
of its disks, then it probably should not be disconnected. If a second Ethernet adapter is
used, be aware that Windows TCP/IP will send messages to one adapter or the other,
depending on the IP address and the binding order in Microsoft products. Thus you should
have different ranges of IP addresses on your private network from those used on the corporate network. If both networks service the same IP address, then Windows may send a
packet intended for your private network to the corporate network. A similar situation will
take place if you use a dial-up line to send a packet to the Internet. Windows may try to
send it via the local Ethernet network if it is also valid for that network.
The following IP addresses are set aside for local networks and are not allowed on the
Internet: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to
192.168.255.255.
The RCM3200 board uses a 10/100Base-T type of Ethernet connection, which is the most
common scheme. The RJ-45 connectors are similar to U.S. style telephone connectors, are
except larger and have 8 contacts.
An alternative to the direct connection using a crossover cable is a direct connection using
a hub. The hub relays packets received on any port to all of the ports on the hub. Hubs are
low in cost and are readily available. The RCM3200 board uses 10 Mbps or 100 Mbps
Ethernet, so the hub or Ethernet adapter must be either a 10 Mbps unit or a 10/100 unit that
adapts to either 10 or 100 Mbps.
In a corporate setting where the Internet is brought in via a high-speed line, there are typically machines between the outside Internet and the internal network. These machines
include a combination of proxy servers and firewalls that filter and multiplex Internet traffic. In the configuration below, the RCM3200 board could be given a fixed address so any
of the computers on the local network would be able to contact it. It may be possible to
configure the firewall or proxy server to allow hosts on the Internet to directly contact the
controller, but it would probably be easier to place the controller directly on the external
network outside of the firewall. This avoids some of the configuration complications by
sacrificing some security.

If your system administrator can give you an Ethernet cable along with its IP address, the
netmask and the gateway address, then you may be able to run the sample programs without having to setup a direct connection between your computer and the RCM3200 board.
You will also need the IP address of the nameserver, the name or IP address of your mail
server, and your domain name for some of the sample programs.

RabbitCore RCM3200
6.2.1 IP Addresses Explained
IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods,
for example:
216.103.126.155
10.1.1.6
Each decimal number must be between 0 and 255. The total IP address is a 32-bit number
consisting of the 4 bytes expressed as shown above. A local network uses a group of adjacent IP addresses. There are always 2N IP addresses in a local network. The netmask (also
called subnet mask) determines how many IP addresses belong to the local network. The
netmask is also a 32-bit address expressed in the same form as the IP address. An example
netmask is:
255.255.255.0
This netmask has 8 zero bits in the least significant portion, and this means that 28
addresses are a part of the local network. Applied to the IP address above
(216.103.126.155), this netmask would indicate that the following IP addresses belong to
the local network:
216.103.126.0
216.103.126.1
216.103.126.2
etc.
216.103.126.254
216.103.126.255
The lowest and highest address are reserved for special purposes. The lowest address
(216.102.126.0) is used to identify the local network. The highest address
(216.102.126.255) is used as a broadcast address. Usually one other address is used for the
address of the gateway out of the network. This leaves 256 - 3 = 253 available IP
addresses for the example given.
User’s Manual
47
6.2.2 How IP Addresses are Used
The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also
called MAC addresses). These are 48-bit addresses and are unique for every Ethernet
adapter manufactured. In order to send a packet to another computer, given the IP address
of the other computer, it is first determined if the packet needs to be sent directly to the
other computer or to the gateway. In either case, there is an IP address on the local network to which the packet must be sent. A table is maintained to allow the protocol driver
to determine the MAC address corresponding to a particular IP address. If the table is
empty, the MAC address is determined by sending an Ethernet broadcast packet to all
devices on the local network asking the device with the desired IP address to answer with
its MAC address. In this way, the table entry can be filled in. If no device answers, then
the device is nonexistent or inoperative, and the packet cannot be sent.
IP addresses are arbitrary and can be allocated as desired provided that they don’t conflict
with other IP addresses. However, if they are to be used with the Internet, then they must
be numbers that are assigned to your connection by proper authorities, generally by delegation via your service provider.
Each RCM3200 RabbitCore module has its own unique MAC address, which consists of
the prefix 0090C2 followed by the code that appears on the label affixed to the RCM3200
module. For example, a MAC address might be 0090C2C002C0.
TIP: You can always verify the MAC address on your board by running the sample program DISPLAY_MAC.C from the SAMPLES\TCPIP folder.
48
RabbitCore RCM3200
6.2.3 Dynamically Assigned Internet Addresses
In many instances, there are no fixed IP addresses. This is the case when, for example, you
are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or
when you have a device that provides your IP addresses using the Dynamic Host Configuration Protocol (DHCP). The RCM3200 RabbitCore modules can use such IP addresses to
send and receive packets on the Internet, but you must take into account that this IP
address may only be valid for the duration of the call or for a period of time, and could be
a private IP address that is not directly accessible to others on the Internet. These private
address can be used to perform some Internet tasks such as sending e-mail or browsing the
Web, but usually cannot be used to participate in conversations that originate elsewhere on
the Internet. If you want to find out this dynamically assigned IP address, under Windows
XP you can run the ipconfig program while you are connected and look at the interface
used to connect to the Internet.
Many networks use private IP addresses that are assigned using DHCP. When your computer comes up, and periodically after that, it requests its networking information from a
DHCP server. The DHCP server may try to give you the same address each time, but a
fixed IP address is usually not guaranteed.
If you are not concerned about accessing the RCM3200 from the Internet, you can place
the RCM3200 on the internal network using a private address assigned either statically or
through DHCP.
User’s Manual
49
6.3 Placing Your Device on the Network
In many corporate settings, users are isolated from the Internet by a firewall and/or a
proxy server. These devices attempt to secure the company from unauthorized network
traffic, and usually work by disallowing traffic that did not originate from inside the network. If you want users on the Internet to communicate with your RCM3200, you have
several options. You can either place the RCM3200 directly on the Internet with a real
Internet address or place it behind the firewall. If you place the RCM3200 behind the firewall, you need to configure the firewall to translate and forward packets from the Internet
to the RCM3200.

6.4 Running TCP/IP Sample Programs
We have provided a number of sample programs demonstrating various uses of TCP/IP for
networking embedded systems. These programs require you to connect your PC and the
RCM3200 board together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet.

6.4.1 How to Set IP Addresses in the Sample Programs
With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. Instead of the MY_IP_ADDRESS and other macros, you will
see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a
list of default configurations. You will have three choices when you encounter a sample
program with the TCPCONFIG macro.
1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS,
MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program.
2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations
to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway
to 10.10.6.1. If you would like to change the default values, for example, to use an IP
address of 10.1.1.2 for the RCM3200 board, and 10.1.1.1 for your PC, you can edit
the values in the section that directly follows the “General Configuration” comment in
the TCP_CONFIG.LIB library. You will find this library in the LIB/TCPIP directory.
3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater
than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB file.
There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the
TCP_CONFIG.LIB library. More information is available in the Dynamic C TCP/IP
User’s Manual.
IP Addresses Before Dynamic C 7.30
Most of the sample programs such as shown in the example below use macros to define the
IP address assigned to the board and the IP address of the gateway, if there is a gateway.
#define
#define
#define
#define
MY_IP_ADDRESS "10.10.6.170"
MY_NETMASK "255.255.255.0"
MY_GATEWAY "10.10.6.1"
MY_NAMESERVER "10.10.6.1"
In order to do a direct connection, the following IP addresses can be used for the RCM3200:
#define MY_IP_ADDRESS "10.1.1.2"
#define MY_NETMASK "255.255.255.0"
// #define MY_GATEWAY "10.10.6.1"
// #define MY_NAMESERVER "10.10.6.1"
In this case, the gateway and nameserver are not used, and are commented out. The IP
address of the board is defined to be 10.1.1.2. The IP address of your PC can be defined
as 10.1.1.1.
52
RabbitCore RCM3200
6.4.2 How to Set Up your Computer’s IP Address for Direct Connect
When your computer is connected directly to the RCM3200 board via an Ethernet connection, you need to assign an IP address to your computer. To assign the PC the address
10.10.6.101 with the netmask 255.255.255.0, do the following.
Click on Start > Settings > Control Panel to bring up the Control Panel, and then double-click the Network icon. Depending on which version of Windows you are using, look
for the TCP/IP Protocol/Network > Dial-Up Connections/Network line or tab. Doubleclick on this line or select Properties or Local Area Connection > Properties to bring
up the TCP/IP properties dialog box. You can edit the IP address and the subnet mask
directly. (Disable “obtain an IP address automatically.”) You may want to write down the
existing values in case you have to restore them later. It is not necessary to edit the gateway address since the gateway is not used with direct connect.

6.5 Run the PINGME.C Sample Program
Connect the crossover cable from your computer’s Ethernet port to the RCM3200 board’s
RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP
folder, compile the program, and start it running under Dynamic C. When the program
starts running, the green LNK light on the RCM3200 board should be on to indicate an
Ethernet connection is made. (Note: If the LNK light does not light, you may not have a
crossover cable, or if you are using a hub perhaps the power is off on the hub.)
The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the pingme program:
ping 10.10.6.100
or by Start > Run
and typing the entry
ping 10.10.6.100
Notice that the red ACT light flashes on the RCM3200 board while the ping is taking
place, and indicates the transfer of data. The ping routine will ping the board four times
and write a summary message on the screen describing the operation.
6.6 Running More Sample Programs With Direct Connect
The sample programs discussed here are in the Dynamic C SAMPLES\RCM3200\TCPIP\
folder.
• BROWSELED.C—This program demonstrates a basic controller running a Web page.
Two “LEDs” are created on the Web page, and two buttons on the Prototyping Board
then toggle them. Users can change the status of the lights from the Web browser. The
LEDs on the Prototyping Board match the ones on the Web page. As long as you have
not modified the TCPCONFIG 1 macro in the sample program, enter the following server
address in your Web browser to bring up the Web page served by the sample program.
http://10.10.6.100.
Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.
• ECHOCLIENT.C—This program demonstrates a basic client that will send a packet and
wait for the connected server to echo it back. After every number of sends and receives,
transfer times are shown in the STDIO window.
Use ECHO_SERVER.C to program a server controller.
• ECHOSERVER.C—This program demonstrates a basic server that will echo back any
data sent from a connected client.
Use ECHO_CLIENT.C to program a client controller.
• ENET_AD.C—This program demonstrates Ethernet communication between two
single-board computers. The program sends an A/D voltage value to the second singleboard computer via Ethernet for display.
Use ENET_MENU.C to program the other single-board computer.
54
RabbitCore RCM3200
• ENET_MENU.C—This program demonstrates how to implement a menu system using a
highlight bar on a graphic LCD display and to communicate it to another single-board
computer via Ethernet.
Use ENET_AD.C to program the other single-board computer with analog inputs and
outputs.
• MBOXDEMO.C—Implements a Web server that allows e-mail messages to be entered
and then shown on the LCD/keypad module.
• SMTP.C—This program allows you to send an E-mail when a switch on the Prototyping Board is pressed. Follow the instructions included with the sample program.
• PINGLED.C—This program demonstrates ICMP by pinging a remote host. It will flash
LEDs DS1 and DS2 on the Prototyping Board when a ping is sent and received.
6.7 Where Do I Go From Here?

It is recommended that you allow for an “exclusion zone” of 0.04" (1 mm) around the
RCM3200 in all directions (except above the RJ-45 plug) when the RCM3200 is incorporated into an assembly that includes other printed circuit boards. This “exclusion zone”
that you keep free of other components and boards will allow for sufficient air flow, and
will help to minimize any electrical or electromagnetic interference between adjacent
boards. An “exclusion zone” of 0.08" (2 mm) is recommended below the RCM3200
when the RCM3200 is plugged into another assembly using the shortest connectors for
headers J1 and J2. Figure A-2 shows this “exclusion zone.”

The measurements are taken at the 50% points under the following conditions.
• T = -40°C to 85°C, V = VDD ±10%
• Internal clock to nonloaded CLK pin delay ≤ 1 ns @ 85°C/3.0 V
The clock to address output delays are similar, and apply to the following delays.
• Tadr, the clock to address delay
• TCSx, the clock to memory chip select delay
• TIOCSx, the clock to I/O chip select delay
• TIORD, the clock to I/O read strobe delay
• TIOWR, the clock to I/O write strobe delay
• TBUFEN, the clock to I/O buffer enable delay
The data setup time delays are similar for both Tsetup and Thold.
When the spectrum spreader is enabled with the clock doubler, every other clock cycle is
shortened (sometimes lengthened) by a maximum amount given in the table above. The
shortening takes place by shortening the high part of the clock. If the doubler is not
enabled, then every clock is shortened during the low part of the clock period. The maximum shortening for a pair of clocks combined is shown in the table.

A.4 I/O Buffer Sourcing and Sinking Limit
Unless otherwise specified, the Rabbit I/O buffers are capable of sourcing and sinking
6.8 mA of current per pin at full AC switching speed. Full AC switching assumes a
29.4 MHz CPU clock and capacitive loading on address and data lines of less than 70 pF
per pin. The absolute maximum operating voltage on all I/O is 5.5 V.
Table A-6 shows the AC and DC output drive limits of the parallel I/O buffers when the
Rabbit 3000 is used in the RCM3200.

APPENDIX B. PROTOTYPING BOARD
Appendix B describes the features and accessories of the Prototyping Board, and explains the use of the Prototyping Board to
demonstrate the RCM3200 and to build prototypes of your own
circuits.
User’s Manual
71
B.1 Introduction
The Prototyping Board included in the Development Kit makes it easy to connect an
RCM3200 module to a power supply and a PC workstation for development. It also provides some basic I/O peripherals (switches and LEDs), as well as a prototyping area for
more advanced hardware development.
For the most basic level of evaluation and development, the Prototyping Board can be
used without modification.
As you progress to more sophisticated experimentation and hardware development, modifications and additions can be made to the board without modifying or damaging the
RCM3200 module itself.
The Prototyping Board is shown below in Figure B-1, with its main features identified.

RabbitCore RCM3200
B.1.1 Prototyping Board Features
• Power Connection—A power-supply jack and a 3-pin header are provided for connection to the power supply. Note that the 3-pin header is symmetrical, with both outer
pins connected to ground and the center pin connected to the raw V+ input. The cable
of the AC adapter provided with the North American version of the Development Kit
ends in a plug that connects to the power-supply jack. The header plug leading to bare
leads provided for overseas customers can be connected to the 3-pin header in either
orientation.
Users providing their own power supply should ensure that it delivers 8–24 V DC at
8 W. The voltage regulators will get warm while in use.
• Regulated Power Supply—The raw DC voltage provided at the POWER IN jack is
routed to a 5 V switching voltage regulator, then to a separate 3.3 V linear regulator.
The regulators provide stable power to the RCM3200 module and the Prototyping
Board.
• Power LED—The power LED lights whenever power is connected to the Prototyping
Board.
• Reset Switch—A momentary-contact, normally open switch is connected directly to the
RCM3200’s /RESET_IN pin. Pressing the switch forces a hardware reset of the system.
• I/O Switches and LEDs—Two momentary-contact, normally open switches are connected to the PG0 and PG1 pins of the master RCM3200 module and may be read as
inputs by sample applications.
Two LEDs are connected to the PG6 and PG7 pins of the master module, and may be
driven as output indicators by sample applications.
• Prototyping Area—A generous prototyping area has been provided for the installation
of through-hole components. +3.3 V, +5 V, and Ground buses run around the edge of
this area. Several areas for surface-mount devices are also available. (Note that there
are SMT device pads on both top and bottom of the Prototyping Board.) Each SMT pad
is connected to a hole designed to accept a 30 AWG solid wire.
• Master Module Connectors—A set of connectors is pre-wired to permit installation
of the first RCM3000, RCM3100, or RCM3200 module that serves as the primary or
“master module.”
• Slave Module Connectors—A second set of connectors is pre-wired to permit installation of a second, slave RCM3200, RCM3100, or RCM3000 module. This capability
is reserved for future use, although the schematics in this manual contain all of the
details an experienced developer will need to implement a master-slave system.
• Module Extension Headers—The complete pin sets of both the MASTER and
SLAVE RabbitCore modules are duplicated at these two sets of headers. Developers
can solder wires directly into the appropriate holes, or, for more flexible development,
26-pin header strips can be soldered into place. See Figure B-4 for the header pinouts.
User’s Manual
73
• RS-232—Two 3-wire or one 5-wire RS-232 serial port are available on the Prototyping
Board. Refer to the Prototyping Board schematic (090-0137) for additional details.
A 10-pin 0.1-inch spacing header strip is installed at J5 to permit connection of a ribbon
cable leading to a standard DE-9 serial connector.
• Current Measurement Option—Jumpers across pins 1–2 and 5–6 on header JP1 can
be removed and replaced with an ammeter across the pins to measure the current drawn
from the +5 V or the +3.3 V supplies, respectively.
• Motor Encoder—A motor/encoder header is provided at header J6 for future use.
• LCD/Keypad Module—Rabbit’s LCD/keypad module may be plugged in directly to
headers J7, J8, and J10.

The RCM3200 requires a regulated 3.3 V ± 0.15 V DC power source to operate. Depending on the amount of current required by the application, different regulators can be used
to supply this voltage.
The Prototyping Board has an onboard +5 V switching power regulator from which a
+3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the
Prototyping Board.
The Prototyping Board itself is protected against reverse polarity by a Shottky diode at D2
as shown in Figure B-3.

B.4 Using the Prototyping Board
The Prototyping Board is actually both a demonstration board and a prototyping board. As
a demonstration board, it can be used to demonstrate the functionality of the RCM3200
right out of the box without any modifications to either board. There are no jumpers or dip
switches to configure or misconfigure on the Prototyping Board so that the initial setup is
very straightforward.
The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM3200. Two LEDs (DS1 and DS2) are connected to PG6 and PG7,
and two switches (S2 and S3) are connected to PG1 and PG0 to demonstrate the interface
to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the
RCM3200.
The Prototyping Board provides the user with RCM3200 connection points brought out conveniently to labeled points at headers J2 and J4 on the Prototyping Board. Small to medium
circuits can be prototyped using point-to-point wiring with 20 to 30 AWG wire between the
prototyping area and the holes at locations J2 and J4. The holes are spaced at 0.1" (2.5 mm),
and 40-pin headers or sockets may be installed at J2 and J4. The pinouts for locations J2 and
J4, which correspond to headers J1 and J2, are shown in Figure B-4.

(Top View)
The small holes are also provided for surface-mounted components that may be installed
around the prototyping area.
There is a 2.0" × 3.5" through-hole prototyping space available on the Prototyping Board.
+3.3 V, +5 V, and GND traces run along the edge of the Prototyping Board for easy access.
User’s Manual
77
B.4.1 Adding Other Components
There are pads that can be used for surface-mount prototyping involving SOIC devices.
There is provision for seven 16-pin devices (six on one side, one on the other side). There
are 10 sets of pads that can be used for 3- to 6-pin SOT23 packages. There are also pads
that can be used for SMT resistors and capacitors in an 0805 SMT package. Each component has every one of its pin pads connected to a hole in which a 30 AWG wire can be soldered (standard wire wrap wire can be soldered in for point-to-point wiring on the
Prototyping Board). Because the traces are very thin, carefully determine which set of
holes is connected to which surface-mount pad.
B.4.2 Measuring Current Draw
The Prototyping Board has a current-measurement feature available on header JP1. Normally, a jumper connects pins 1–2 and pins 5–6 on header JP1, which provide jumper connections for the +5 V and the +3.3 V regulated voltages respectively. You may remove a
jumper and place an ammeter across the pins instead, as shown in the example in
Figure B-5, to measure the current being drawn.

B.4.3 Other Prototyping Board Modules and Options
With the RCM3200 plugged into the MASTER slots, it has full access to the RS-232 transceiver, and can act as the “master” relative to another RabbitCore RCM3000, RCM3100,
or RCM3200 plugged into the SLAVE slots, which acts as the “slave.”
An optional LCD/keypad module is available that can be mounted on the Prototyping
Board. Refer to Appendix C, “LCD/Keypad Module,” for complete information.
The RCM3200 has a 2-channel quadrature decoder and a 10-bit free-running PWM
counter with four pulse-width registers. These features allow the RCM3200 to be used in a
motor control application, although Rabbit does not offer the drivers or a compatible stepper motor control board at this time.
The Prototyping Board has a header at J6 to which a customer-developed motor encoder
may be connected. Figure B-6 shows the motor encoder pinout at header J6.

C.2 Contrast Adjustments for All Boards
Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast
based on the voltage of the system they would be used in. Be sure to select a KDU5V
LCD/keypad module for use with the RCM3000/3100/3200 Prototyping Board — these
modules operate at 5 V. You may adjust the contrast using the potentiometer at R2 as
shown in Figure C-3. LCD/keypad modules configured for 3.3 V should not be used with
the 5 V RCM3000/3100/3200 Prototyping Board because the higher voltage will reduce
the backlight service life dramatically.

C.8 Sample Programs
Sample programs illustrating the use of the LCD/keypad module with the Prototyping
Board are provided in the SAMPLES\RCM3200 directory.
These sample programs use the external I/O bus on the Rabbit 3000 chip, and so the
#define PORTA_AUX_IO line is already included in the sample programs.
Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program. To run a sample
program, open it with the File menu (if it is not still open), compile it using the Compile
menu, and then run it by selecting Run in the Run menu. The RCM3200 must be in
Program mode (see Section 4.3, “Serial Programming Cable”), and must be connected to
a PC using the programming cable as described in the RCM3200 Getting Started Manual.
More complete information on Dynamic C is provided in the Dynamic C User’s Manual.
The following sample programs are found in the SAMPLES\RCM3200\LCD_KEYPAD folder.
• KEYPADTOLED.C—This program demonstrates the use of the external I/O bus. The
program will light up an LED on the LCD/keypad module and will display a message
on the LCD when a key press is detected. The DS1 and DS2 LEDs on the Prototyping
Board will also light up.
• LCDKEYFUN.C—This program demonstrates how to draw primitive features from the
graphic library (lines, circles, polygons), and also demonstrates the keypad with the key
release option.
• SWITCHTOLED.C—This program demonstrates the use of the external I/O bus. The
program will light up an LED on the LCD/keypad module and will display a message
on the LCD when a switch press is detected. The DS1 and DS2 LEDs on the Prototyping Board will also light up.

APPENDIX D. POWER SUPPLY
Appendix D provides information on the current requirements
of the RCM3200, and includes some background on the chip
select circuit used in power management.
D.1 Power Supplies
The RCM3200 requires a regulated 3.3 V ± 0.15 V DC power source. The RabbitCore
design presumes that the voltage regulator is on the user board, and that the power is made
available to the RCM3200 board through header J2.
An RCM3200 with no loading at the outputs operating at 29.4 MHz typically draws 145 mA.
The RCM3200 will consume an additional 10 mA when the programming cable is used to
connect the programming header, J3, to a PC.
D.1.1 Battery Backup
The RCM3200 does not have a battery, but there is provision for a customer-supplied battery to back up the data SRAM and keep the internal Rabbit 3000 real-time clock running.
Header J2, shown in Figure D-1, allows access to the external battery. This header makes
it possible to connect an external 3 V power supply. This allows the SRAM and the internal Rabbit 3000 real-time clock to retain data with the RCM3200 powered down.

Figure D-1. External Battery Connections
at Header J2
A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA·h is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
User’s Manual
113
The drain on the battery by the RCM3200 is typically 12 µA when no other power is supplied. If a 165 mA·h battery is used, the battery can last almost 2 years:
165 mA·h
------------------------ = 1.6 years.
12 µA
The actual life in your application will depend on the current drawn by components, not
on the RCM3200 and the storage capacity of the battery. The RCM3200 does not drain the
battery while it is powered up normally.
Cycle the main power off/on on the RCM3200 after you install a backup battery for the
first time, and whenever you replace the battery. This step will minimize the current drawn
by the real-time clock oscillator circuit from the backup battery should the RCM3200
experience a loss of main power.
NOTE: Remember to cycle the main power off/on any time the RCM3200 is removed
from the Protoyping Board or motherboard since that is where the backup battery
would be located.
Rabbit’s Technical Note TN235, External 32.768 kHz Oscillator Circuits, provides additional information about the current draw by the the real-time clock oscillator circuit.

Figure D-2. RCM3200 Backup Battery Circuit
The battery-backup circuit serves three purposes:
• It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting
the current consumed by the real-time clock and lengthening the battery life.
• It ensures that current can flow only out of the battery to prevent charging the battery.
• A voltage, VOSC, is supplied to U5, which keeps the 32.768 kHz oscillator working
when the voltage begins to drop.

RabbitCore RCM3200
D.1.3 Reset Generator
The RCM3200 uses a reset generator to reset the Rabbit 3000 microprocessor when the
voltage drops below the voltage necessary for reliable operation. The reset occurs between
2.85 V and 3.00 V, typically 2.93 V. The RCM3200 has a reset output, pin 1 on header J2.
D.2 Optional +5 V Output
The RCM3200 boards have an onboard charge pump that provides the +5 V needed by the
RealTek Ethernet chip.

APPENDIX E. MOTOR CONTROL OPTION
The Prototyping Board has a header at J6 for a motor control option.
While Rabbit does not support this option at this time, this appendix
provides additional information about Parallel Port F on the Rabbit
3000 microprocessor to enable you to use this feature on the Prototyping Board for your needs.
E.1 Overview
The Parallel Port F connector on the Prototyping Board, J6, gives access to all 8 pins of
Parallel Port F, along with +5 V. This appendix describes the function of each pin, and the
ways they may be used for motion-control applications. It should be read in conjunction
with the Rabbit 3000 Microprocessor User’s Manual and the RCM3200 and the Prototyping Board schematics.

All Parallel Port F lines (pins 1 to 8) are pulled up internally to +3.3 V via 100 kΩ resistors. When used as outputs, the port pins will sink up to 6 mA at a VOL of 0.4 V max.
(0.2 V typ), and source up to 6 mA at a VOH of 2.2 V typ. When used as inputs, all pins
are 5 V tolerant.
As the outputs from Parallel Port F are compatible with 3.3 V logic, buffers may be
needed when the external circuit drive requirements exceed the 2.2 V typ logic high and/or
the 6 mA maximum from the Rabbit 3000. The +5 V supply output is provided for supplying interface logic. When used as inputs, the pins on header J6 do not require buffers
unless the input voltage will exceed the 5 V tolerance of the processor pins. Usually, a
simple resistive divider with catching diodes will suffice if higher voltage inputs are
required. If the outputs are configured for open-drain operation, they may be pulled up to
+5 V (while observing the maximum current, of course).
118
RabbitCore RCM3200
E.3 Using Parallel Port F
Parallel Port F is a byte-wide port with each bit programmable for data direction and drive.
These are simple inputs and outputs controlled and reported in the Port F Data Register.
As outputs, the bits of the port are buffered, with the data written to the Port F Data Register transferred to the output pins on a selected timing edge. The outputs of Timer A1,
Timer B1, or Timer B2 can be used for this function, with each nibble of the port having a
separate select field to control this timing. These inputs and outputs are also used for
access to other peripherals on the chip.
As outputs, Parallel Port F can carry the four Pulse Width Modulator outputs on PF4–PF 7
(J6, pins 5–8). As inputs, Parallel Port F can carry the inputs to the Quadrature Decoders
on PF0–PF3 (J6, pins 1–4). When Serial Port C or Serial Port D is used in clocked serial
mode, two pins of Port F (PF0 / J6:1 and PF1 / J6:2) are used to carry the serial clock signals. When the internal clock is selected in these serial ports, the corresponding bit of Parallel Port F is set as an output.
E.3.1 Parallel Port F Registers
Data Direction Register—PFDDR, address 00111111 (0x3F), write-only, default value on
reset 00000000. For each bit position, write a 1 to make the corresponding port line an
output, or 0 to produce an input.
Drive Control Register—PFDCR, address 00111110 (0x3E), Write-only, no default on
reset (port defaults to all inputs). Effective only if the corresponding port bits are set as
outputs, each bit set to 1 configures the corresponding port bit as open drain. Setting the
bit to 0 configures that output as active high or low.
Function Register—PFFR, address 00111101 (0x3D), Write-only, no default on reset.
This register sets the alternate output function assigned to each of the pins of the port.
When set to 0, the corresponding port pin functions normally as an output (if configured to
be an output in PFDDR). When set to 1, each bit sets the corresponding pin to have the
alternate output function as shown in the summary table at the end of this section.
Control Register—PFCR, address 00111100 (0x3C), Write-only, default on reset
xx00xx00. This register sets the transfer clock, which controls the timing of the outputs on
each nibble of the output ports to allow close synchronization with other events. The summary table at the end of this section shows the settings for this register. The default values
on reset transfer the output values on CLK/2.
Data Register—PFDR, address 00111000 (0x38), Read or Write, no default value on
reset. On read, the current state of the pins is reported. On write, the output buffer is written with the value for transfer to the output port register on the next rising edge of the
transfer clock, set in the PFCR.

E.4 PWM Outputs
The Pulse-Width Modulator consists of a 10-bit free-running counter and four width registers. Each PWM output is high for n + 1 counts out of the 1024-clock count cycle, where n
is the value held in the width register. The PWM output high time can optionally be spread
throughout the cycle to reduce ripple on the externally filtered PWM output. The PWM is
clocked by the output of Timer A9. The spreading function is implemented by dividing
each 1024-clock cycle into four quadrants of 256 clocks each. Within each quadrant, the
Pulse-Width Modulator uses the eight MSBs of each pulse-width register to select the base
width in each of the quadrants. This is the equivalent to dividing the contents of the pulsewidth register by four and using this value in each quadrant. To get the exact high time, the
Pulse-Width Modulator uses the two LSBs of the pulse-width register to modify the high
time in each quadrant according to Table E-3 below. The “n/4” term is the base count, and
is formed from the eight MSBs of the pulse-width register.

E.6 Quadrature Decoder
The two-channel Quadrature Decoder accepts inputs via Parallel Port F from two external
optical incremental encoder modules. Each channel of the Quadrature Decoder accepts an
in-phase (I) and a quadrature-phase (Q) signal, and provides 8-bit counters to track shaft
rotation and provide interrupts when the count goes through the zero count in either direction. The Quadrature Decoder contains digital filters on the inputs to prevent false counts
and is clocked by the output of Timer A10. Each Quadrature Decoder channel accepts
inputs from either the upper nibble or lower nibble of Parallel Port F. The I signal is input
on an odd-numbered port bit, while the Q signal is input on an even-numbered port bit.
There is also a disable selection, which is guaranteed not to generate a count increment or
decrement on either entering or exiting the disable state. The operation of the counter as a
function of the I and Q inputs is shown below.

Figure E-2. Operation of Quadrature Decoder Counter
The Quadrature Decoders are clocked by the output of Timer A10, giving a maximum
clock rate of one-half of the peripheral clock rate. The time constant of Timer A10 must be
fast enough to sample the inputs properly. Both the I and Q inputs go through a digital filter that rejects pulses shorter than two clock periods wide. In addition, the clock rate must
be high enough that transitions on the I and Q inputs are sampled in different clock cycles.
The Input Capture (see the Rabbit 3000 Microprocessor Users Manual) may be used to
measure the pulse width on the I inputs because they come from the odd-numbered port
bits. The operation of the digital filter is shown below.
