Notes
1. When using pins 33–34 on header J1 to drive LEDs, you must us e an external buf fer 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 volt-
age 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.

2.1.1 Memory I/O Interface
The Rabbit 3000 address lines (A0–A19) and all the data lines (D0–D7) are routed inter-
nally 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 auxiliary I/O bus, you must add the following line at the beginning of
your program.
#define PORTA_AUX_IO // required to enable auxiliary 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.
2.1.2 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.
12 RabbitCore RCM3200
2.2 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.
2.2.1 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 sup-
ply the clock.
Serial Ports E and F can also be configured as SDLC/HDLC serial ports. The IrDA proto-
col is also supported in SDLC format by these two ports.
2.2.2 Ethernet Port
Figure 4 shows the pinout for the RJ-45 Ethernet port (J4). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
Figure 4. RJ-45 Ethernet Port Pinout
Three LEDs are placed next to the RJ-45 Ethernet
jack, one to indicate an Ethernet link (LNK), one to
indicate Ethernet activity (ACT), and one to indi-
cate when the RCM3200 is connected to a function-
ing 100Base-T network (SPD).
The transformer/conne ctor assembly ground is con-
nected to the RCM3200 printed circuit board digital
ground via a 0 Ω resistor, R42, as shown in Figure 5.
The RJ-45 connector is shielded to minimize EMI
effects to/from the Ethernet signals.

2.2.3 Programming Port
Serial Port A has special features that allow it to cold-boot the system after reset. Serial
Port A is also the port that is used for software development under Dynamic C.
The RCM3200 has a 10-pin program header labeled J3. The Rabbit 3000 startup-mode
pins (SMODE0, SMODE1) are presented to the programming port so that an externally
connected device can force the RCM3200 to start up in an external bootstrap mode. The
Rabbit 3000 Microprocessor User’s Manual provides more information related to the
bootstrap mode.
The programming port is used to start the RCM3200 in a mode where it will download a
program from the port and then execute the program.
The programming port transmits
information to and from a PC while a program is being debugged in-circuit.
The RCM3200 can be reset from the programming port via the /RESET_IN line.
The Rabbit 3000 status pin is also presented to the programming port. The status pin is an
output that can be used to send a general digital signal.
The clock line for Serial Port A is presented to the programming port, which makes syn-
chronous serial communication possible.
Programming may also be initiated through the motherboard to which the RCM3200
series module is pl ugged in to since the Seri al Port A (PC 6 and PC7), S MODE0, SMO DE1,
and /RESET_IN are available on headers J1 and J2 (see Table 1).
2.2.3.1 Alternate Uses of the Programming Port
The programming port may also be used as an application port with the DIAG connector
on the programming cable.
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 input
•two general CMOS inputs and one general CMOS output.
Two startup mode pins, SMODE0 and SMODE1, are available as general CMOS inputs
after they are read during the initial boot-up. The logic state of these two pins is very
important in determining the startup procedure after a reset.
/RES_IN is an external input used to reset the Rabbit 3000 microprocessor.
The status pin may also be used as a general CMOS output.
See Appendix E, “Programming Cable,” for more information.
14 RabbitCore RCM3200
2.3 Programming Cable
The RCM3200 is automatically in program mode when the
PROG connector on the pro-
gramming ca ble is attached, and i s automatically in run mode when no programming cable
is attached.
The DIAG connector of the programming cable may be used on header J3 of the RCM3200
with the board operating in the run mode. This a llows the progr ammin g port to be use d as
an application port. See Appendix E, “Programming Cable,” for more information.
Figure 6. Switching Between Program Mode and Run Mode
2.3.1 Changing from Program Mode to Run Mode
1. Disconnect the programming cable from header J3 of the RCM3200.
2. Reset the RCM3200. You may do this as explained in Figure 6.

2.4 Other Hardware
2.4.1 Clock Doubler
The RCM3200 takes advantage of the Rabbit 3000 microprocessor’s internal clock dou-
bler. 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 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 change
to the BIOS as described below.
2.4.2 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 change to the following BIOS
line in a way that is similar to the clock doubler described above.
#define ENABLE_SPREADER 1 // Set to 0 to disable spectrum spreader.
#define SPREADER_SETTING 0 // 0 = normal spreading, 1 = strong spreading
NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more infor mation
on the spectrum-spreading setting and the maximum clock speed.
1. Open the BIOS source code file, RABBITBIOS.C in the BIOS directory.
2. Change the line
#define CLOCK_DOUBLED 1 // set to 1 to double clock if
// Rabbit 2000: crystal <= 12.9024 MHz,
// Rabbit 3000: crystal <= 26.7264 MHz,
// or to 0 to always disable clock doubler
to read as follows.
#define CLOCK_DOUBLED 0
3. Save the change using File > Save.
16 RabbitCore RCM3200
2.5 Memory
2.5.1 SRAM
The RCM3200 has 512K of program execution SRAM installed at U8 and packaged in a
32-pin TSOP or sTSOP case. The data SRAM installed at U6 is 256K.
2.5.2 Flash EPROM
The RCM3200 is also designed to accept 256K to 512K of flash EPROM packaged in a
32-pin TSOP or sTSOP case. The flash EPROM installed at U7 is 512K
NOTE: Z-World recommends that any cust omer applications should not be constr ain ed
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.
A Flash Memor y Bank Select jum per 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 the 512K flash in such a way that
both programs start at logical address 0000. This is useful for applications that require a
resident download manager and a separate downloaded program. See Technical Note
TN218, Implementing a Serial Download Manager for a 256K Flash, for details.
2.5.3 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.
User’s Manual 17
3. 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 Z-World controllers and other controllers
based on the Rabbit microprocessor. Chapter 3 provides the
libraries, function calls, and sample programs related to the
RCM3200.
3.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. It is specially designed for program-
ming 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 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 can be developed in the data SRAM, but should be run from the
program execution SRAM after the programming cable is disconnected. To run the
application in the fast program execution SRAM, select Code and BIOS in Flash,
Run in RAM from the Dynamic C Options > Compiler menu.
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 accommo-
date flash devices with various sector sizes.
The disadvantage of using flash memory for debug is that interrupts must be disabled for
approximately 5 ms whenever a break point is set in the program. This can crash fast inter-
rupt routines that are running while you stop at a break point or single-step the program.
The flash memory and SRAM options are selected with the Optio n s > Comp ile r menu.
Dynamic C provides a number of debugging features. You can single-step your program,
either in C, statement by statement, or in assembly language, instruction by instruction.
You can set break points, where the program will stop, on any statement. You can evaluate
watch expressions. A watch expression is any C expression that can be evaluated in the
context of the program. If the program is at a break point, a watch expression
can view a ny
expression using local or global va riables. If a periodic call to
runwatch()
is included in
your program, you will be able to evaluate watch expressions by hitting <Ctrl-U> without
stopping the program.

3.2 Dynamic C Functions
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.
3.2.1 Board Initialization
Call this function at the beginning of you r program. This functio n initializes Parallel Ports A through G
for use with the RCM3200 Prototyping Board.
Summary of Initializa tion
1. I/O port pins are configured for Prototyping Board operation.
2. U nused co nfigurab le I/ O are set a s high outp uts.
3. Only one RabbitCore module is p lugged in, and is in the MASTER position on the Prototypin g
Board.
3. The LCD/keypad module is disabled.
4. RS-485 is not enabled.
5. RS-232 is not enabled.
6. The IrDA transceiver is disabled.
7. LEDs are off.
RETURN VALUE
None.
void brdInit (void);
User’s Manual 19
3.2.2 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 auxiliary I/O bus on the Rabbit 3000 chip, add the line
#define PORTA_AUX_IO // required to enable auxiliary I/O bus
to the beginning of any programs using the auxiliary I/O bus.
The sample programs in the Dynamic C
SAMPLES/RCM3200
directory provide further
examples.
3.2. 3 Seri al Communication Dr ivers
Library files included with Dynamic C provide a full range of serial communications sup-
port. 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 delim-
ited 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 transmit-
ting 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.
3.2.4 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.
20 RabbitCore RCM3200
3.3 Sample Programs
Sample programs are provided in the Dynamic C
Samples
folder.
Two subdirectories contain sample programs that illustrate features unique to the
RCM3200.
• RCM3200—Demonstrates the basic operation and the Ethernet functionality of the
RCM3200.
• TCPIP—Demonstrates more advanced TCP/IP programming for Z-World’s Ethernet-
enabled Rabbit-based boards.
Follow the instructions included with the sample program to connect the RCM3200 and
the other hardware identified in the instructions.
Before running any Dynamic C applications, you will need to allow the compiler to run
the application in the fast program execution SRAM by selecting Code and BIOS in
Flash, Ru n in RAM from the Compiler tab in the Dynamic C Options > P roject Opt ions
menu.
To run a sample program, open it with the File menu (if it is not still open), compile it
using the Compile menu (or press F5), and then run it by selecting Run in the Run menu
(or press F9). The RCM3200 must be in Program Mode (see Figure 6) and must be con-
nected to a PC using the programming cable.
More complete information on Dynamic C is provided in the Dynamic C User’s Manual.

User’s Manual 25
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 incorpo-
rated 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.”

A.1.1 Header s
The RCM3200 uses headers at J1 and J2 for physical connection to other boards. J1 and J2
are 2 × 17 SMT headers with a 2 mm pin spacing. J3, the programming port, is a 2 × 5
header with a 1.27 mm pin spacing.
Figure A-3 shows the layout of another board for the RCM3200 to be plugged int o. These
values are relative to the mounting hole.
A.1.2 Physical Mounting
A 9/32” (7 mm) standoff with a 2-56 screw is recommended to attach the RCM3200 to a
user board at the hole position shown in Figure A-3
. Either use plastic hardware, or use
insulating washers to keep any metal hardware from shorting out signals on the RCM3200.

Table A-4 lists the delays in gross memory access time for several values of VDD.
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°V/4.5 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 maxi-
mum 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.
Under certain conditio ns, the maxim um instantaneous AC/ DC sourcing or sinking current
may be greater than the limits outlined in Table A-6. The maximum AC/DC sourcing cur-
rent can be as high as 12.5 mA per buffer as long as the number of sourcing buffers does
not exceed three per VDD or VSS pad, or up to six outputs between pads. Similarly, the
maximum AC/DC sinking current can be as high as 8.5 mA per buffer as long as the num-
ber of sinking buffers does not exceed three per VDD or VSS pad, or up to six outputs
between pads. The VDD bus can handle up to 35 mA, and the VSS bus can handle up to
28 mA. All these analyses were measured at 100°C.

A.5 Conformal Coating
The areas around the 32 kHz real-time clock crystal oscillator has had the Dow Corning
silicone-based 1-2620 conformal coating applied. The conformally coated area is shown
in Figure A-5. The conformal coating protects these high-impedance circuits from the
effects of moisture and contaminants over time.
Figure A-5. RCM3200 Areas Receiving Conformal Coating
Any components in the conformally coated area may be replaced using standard soldering
procedures for surface-mounted components. A new conformal coating should then be
applied to offer continuing protection against the effects of moisture and contaminants.
NOTE: For more information on conformal coatings, refer to Technical Note 303, Con-
formal Coatings.

Table B-1 lists the electrical, mechanical, and environmental specifications for the Proto-
typing Board.
B.2 Power Supply
The RCM3200 requires a regulated 3.3 V ± 0.15 V DC power source to operate. Depend-
ing 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-2.

B.3 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 con-
veniently to labeled points at headers
J2 an d J4 on the Prototyp ing 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-3.
Figure B-3. Prototyping Board Pinout
(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.

B.3.1 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 compo-
nent has every one of its pin pads connected to a hole in which a 30 AWG wire can be sol-
dered (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.3.2 Measuring Current Draw
The Prototyping Board has a current-measurement feature available on header JP1. Nor-
mally, a jumper connects pins 1–2 and pins 5–6 on header JP1, which provide jumper con-
nections 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-4, to measure the current being drawn.
Figure B-4. Prototyping Board Current-Measurement Option
B.3.3 Other Prototyping Board Modules and Options
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.
A motor control option is available for development by the customer. Refer to

C.2 Contrast Adjustments for All Boards
Depending on when you acquired your LCD/keypad module, you will be able to set the
contrast on the LCD display by adjusting the potentiometer at R2 or by setting the voltage
for 5 V by not using the jumper across any pins on header J5 as shown in Figure C-2. Only
one of these two options is available on a given LCD/keypad module.
Figure C-2. LCD/Keypad Module Voltage Settings
NOTE: Older LCD/keypad modules that do not have a header at J5 or a contrast adjust-
ment pot entiometer at R 2 are limited to op erate only at 5 V, and will work with t he
Prototyping Board. The older LCD/keypad modules are no longer being sold.

This section describes and illustrates how to bezel-mount the LCD/keypad module. Fol-
low these steps for bezel-mount installation.
1. Cut mounting holes in the mounting p anel in accordance with the recommended dimen-
sions in Figure C-7, then use the bezel faceplate to mount the LCD/keypad module onto
the panel.

3. Fasten the unit with the four 4-40 screws and washers included with the LCD/keypad
module. If your panel is thick, use a 4-40 screw that is approximately 3/16" (5 mm)
longer than the thickness of the panel.
Figure C-8. LCD/Keypad Module Mounted in Panel (rear view)
Carefully tighten the screws until the gasket is compressed and the plastic bezel face-
plate is touching the panel.
Do not tighten each screw fully before moving on to the next screw. Apply only one or
two turns to each screw in sequence until all are tightened manually as far as they can
be so that the ga sket is c ompre ssed and the plastic bezel faceplate is touching the panel.

User’s Manual 71
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 typ ically draws 14 5 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 Circuits
The RCM3200 does not have a battery, but there is provision for a customer-supplied bat-
tery 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 inter-
nal Rabbit 3000 real-time clock to retain data with the RCM3200 powered down.
Figure D-1. External Battery Connections
at Header J5
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.

72 RabbitCore RCM3200
The drain on the battery by the RCM3200
is typically 12 µA when no other power is sup-
plied. If a 165 mA·h battery is used, the battery can last almost 2 years:
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. Note that the shelf life of a lithium ion
battery is ultimately 10 years. The RCM3200 does not drain the battery while it is powered
up normally.
D.1.2 Reset Generator
The RCM3200 uses a reset generator to reset the Rabbit 3000 microprocessor when the volt-
age drops below the voltage necessary for reliable opera tion . The r eset oc curs betwe e n
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 Outpu t
The RCM3200 boards have an onboard charge pump that provides the +5 V needed by the
RealTek Ethernet chip.

APPENDIX E. PROGRAMMING CABLE
Appendix E provides additiona l informat ion for th e Rabbit 3000®
microprocessor when using the DIAG and PROG connectors on the
programming cable. The PROG connector is used only when the pro-
gramming cable is attached to the programming connector (header J3)
while a new app li cat ion is bei ng de vel ope d. Ot her wis e, th e DIAG con-
nector on the programming cable allows the programming cable to be
used as an RS-232 to CMOS level converter for serial communication,
which is appropriate for monitoring or debugging a RabbitCore system
while it is running.
74 RabbitCore RCM3200
The programming port, which is shown in Figure E-1
, can serve as a convenient communica-
tions port for field setup or other occasional communication need (for example, as a diag-
nostic port). If the port is simply to perform a setup function, that is, write setup
information to flash memory, then the controller can be reset through the programming
port and a cold boot performed to start execution of a special program dedicated to this
functionality.
Figure E-1. Programming Port Pin Assignments
When the PROG connector is used, the /RESET line can be asserted by manipulating
DTR and the STATUS line can be read as DSR on the serial port. The target can be
restarted by pulsing reset and then, after a short delay, sending a special character string at
2400 bps. To simply restart the BIOS, the string 80h, 24h, 80h can be sent. When the
BIOS is started, it can tell whether the programming cable is connected because the
SMODE1 and SMODE0 pins are sensed as being high.
Alternatively, the DIAG connector can be used to connect the programming port. The
/RESET line and the SMODE1 and SMODE0 pins are not connected to this connector.
The programming port is then enabled as a diagnostic port by polling the port periodically
to see if communication needs to begin or to enable the port and wait for interrupts. The
pull-up resistors on RXA and CLKA prevent spurious data reception that might take place
if the pins floated.
If the clocked serial mode is used, the serial port can be driven by having two toggling
lines that can be driven and one line that can be sensed. This allows a conversation with a
device that does not have an asynchronous serial port but that has two output signal lines
and one input signal line.
The line TXA (also called PC6) is zero after reset if the cold-boot mode is not enabled. A
possible way to detect the presence of a cable on the programming port is for the cable to
connect TXA to one of the SMODE pins and then test for the connection by raising PC6
(by configuring it as a general output bit) and reading the SMODE pin after the cold-boot
mode has been disabled. The value of the SMODE pin is read from the SPCR register.

APPENDIX F. MOTOR CONTROL OPTION
The Protot yping Board ha s a hea der at J6 for a motor contro l optio n.
While Z-World and Rabb it Semiconduc tor do not support this opti on
at this time, this appendix provides additional information about Paral-
lel Port F on th e Ra bb it 300 0 m ic rop ro ce ss or to en ab le you to use thi s
feature on the Prototyping Board for your needs.
F.1 Overview
The Parallel Port F connector on the Prototyping Board, J6, gives access to all 8 pins of
Parallel Por t 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 Proto-
typing Board schematics.
78 RabbitCore RCM3200
F.2 Header J6
The connector is a 2 × 5, 0.1" pitch header suitable for connecting to a IDC receptacle,
with the following pin allocations.
All Parallel Port F lines (pins 1 to 8) are pulled up internally to +3.3 V via 100 kΩ resis-
tors. 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 supply-
ing 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).

F.3 Using Parallel Port F
Parallel Por t 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 a re buf fe red, with the data wri tten to the Port F Data Re gis-
ter 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 sig-
nals. When the internal clock is selected in these serial ports, the corresponding bit of Par-
allel Port F is set as an output.
F.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 sum-
mary table at the e nd of this s ection s hows 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 writ-
ten with the value for transfer to the output port register on the next rising edge of the
transfer clock, set in the PFCR.

F.4 PW M Outp uts
The Pulse-W i dth Modulator consists of a 10-bit free-running counter and four width regis-
ters. 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-W idth 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 pulse-
width register by four and using t his 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 F-3 below. The “n/4” term is the base count, and
is formed from the eight MSBs of the pulse-width register.
The diagram below shows a PWM output for several different width values for both
modes of operation. Operation in the spread mode reduces the filtering requirements on
the PWM output in most cases.

F.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 direc-
tion. 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 F-2. Operation of Quadrature Decode r 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 T imer A10 must be
fast enough to sample the inputs properly. Both the I and Q inputs go through a digital fil-
ter 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.

User’s Manual 85
The Quadrature Decoder generates an interrupt when the counter increments from 0x00 to
0x01 or when the counter decrements from 0x00 to 0xFF. Note that the status bits in the
QDCSR are set co incident with the inte rrupt, an d the interrupt (and status bits) are cleared
by reading the QDCSR.
