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 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 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 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.

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 supply the clock. 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. 2.2.2 Ethernet Port Figure 4 shows the pinout for the RJ-45 Ethernet port (J4). Note that some Ethernet connectors are numbered in reverse to the order used here.

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 indicate when the RCM3200 is connected to a functioning 100Base-T network (SPD). The transformer/connector assembly ground is connected to the RCM3200 printed circuit board digital ground via a 0 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 synchronous serial communication possible. Programming may also be initiated through the motherboard to which the RCM3200 series module is plugged in to since the Serial Port A (PC6 and PC7), SMODE0, SMODE1, 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.
User's Manual

2.3 Programming Cable
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. 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 allows the programming port to be used as an application port. See Appendix E, "Programming Cable," for more information.

2.4 Other Hardware
2.4.1 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 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. 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. 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 information on the spectrum-spreading setting and the maximum clock speed.

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 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. A Flash Memory Bank Select jumper configuration option based on 0 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.

RabbitCore RCM3200
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 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 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 accommodate 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 interrupt 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 Options > Compiler 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 any expression using local or global variables. If a periodic call to runwatch() is included in your program, you will be able to evaluate watch expressions by hitting 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
void brdInit (void);
Call this function at the beginning of your program. This function initializes Parallel Ports A through G for use with the RCM3200 Prototyping Board. Summary of Initialization 1. I/O port pins are configured for Prototyping Board operation. 2. Unused configurable I/O are set as high outputs. 3. Only one RabbitCore module is plugged in, and is in the MASTER position on the Prototyping 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.

RabbitCore RCM3200
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 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. 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.

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 Ethernetenabled 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, Run in RAM from the Compiler tab in the Dynamic C Options > Project Options 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 connected to a PC using the programming cable. More complete information on Dynamic C is provided in the Dynamic C User's Manual.

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."

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. Technical Note TN227, Interfacing External I/O with Rabbit 2000/3000 Designs, contains suggestions for interfacing I/O devices to the Rabbit 3000 microprocessors.

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.
Table A-6. I/O Buffer Sourcing and Sinking Capability
Output Drive (Full AC Switching) Pin Name Sourcing/Sinking Limits (mA) Sourcing All data, address, and I/O lines with clock doubler enabled 6.8 Sinking 6.8
Under certain conditions, the maximum instantaneous AC/DC sourcing or sinking current may be greater than the limits outlined in Table A-6. The maximum AC/DC sourcing current 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 number 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 100C.

B.2 Power Supply
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-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 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-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" x 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.
38 RabbitCore RCM3200
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 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.3.2 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-4, to measure the current being drawn.

to the beginning of any programs using the auxiliary I/O bus. C.7.1 LEDs When power is applied to the LCD/keypad module for the first time, the red LED (DS1) will come on, indicating that power is being applied to the LCD/keypad module. The red LED is turned off when the brdInit function executes. One function is available to control the LEDs, and can be found in the RCM3200.LIB library in the SAMPLES\RCM3200 directory.
void ledOut(int led, int value);

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 auxiliary I/O bus on the Rabbit 3000 chip, and so the #define PORTA_AUX_IO line is already included in the sample programs.

RabbitCore RCM3200
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 Circuits 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 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.
User's Manual 71
The drain on the battery by the RCM3200 is typically 12 A 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 A
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 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.

RabbitCore RCM3200
APPENDIX E. PROGRAMMING CABLE
Appendix E provides additional information for the Rabbit 3000(R) microprocessor when using the DIAG and PROG connectors on the programming cable. The PROG connector is used only when the programming cable is attached to the programming connector (header J3) while a new application is being developed. Otherwise, the DIAG connector 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.
User's Manual
73
The programming port, which is shown in Figure E-1, can serve as a convenient communications port for field setup or other occasional communication need (for example, as a diagnostic 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 Prototyping Board has a header at J6 for a motor control option. While Z-World and Rabbit Semiconductor do 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.
F.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 k 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).

F.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. 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 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.

F.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 F-3 below. The "n/4" term is the base count, and is formed from the eight MSBs of the pulse-width register.
Table F-3. PWM Outputs
Pulse Width LSBs 00 01 10 11 1st n/4 + 1 n/4 + 1 n/4 + 1 n/4 + 1 n/4 n/4 n/4 + 1 n/4 + 1 2nd n/4 n/4 + 1 n/4 + 1 n/4 + 1 3rd n/4 n/4 n/4 n/4 + 1 4th
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 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.
I input Q input Counter 00 01 02 03 04 05 06 07 08 07 06 05 04 03 02 01 00 FF Interrupt
Figure F-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.
