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 external address bus.
2.2 Serial Communication The RCM3000 Series 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 RCM3000 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 16.
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 RabbitCore RCM3000 Series 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 RCM3000 to start up in an external bootstrap mode.
2.3 Other Hardware 2.3.1 Clock Doubler The RCM3000 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 29.4 MHz frequency specified for the RCM3000 is generated using a 14.7456 MHz crystal. The clock doubler will not work for crystals with a frequency above 26.7264 MHz. The clock doubler may be disabled if 29.4 MHz clock speeds are not required.
2.4 Memory 2.4.1 SRAM The RCM3000 is designed to accept 128K to 512K of SRAM packaged in a 32-pin TSOP or sTSOP case. 2.4.2 Flash EPROM The RCM3000 is also designed to accept 256K to 512K of flash EPROM packaged in a 32-pin TSOP or sTSOP case. 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.

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 RCM3000. 3.1 More About Dynamic C Dynamic C has been in use worldwide since 1989.
3.2 Programming Cable The RCM3000 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 RCM3000 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.
3.3 Dynamic C Libraries With Dynamic C running, click File > Open, and select Lib. The following list of Dynamic C libraries will be displayed. There is no unique library that is specific to the RCM3000. The functions in the above libraries are described in the Dynamic C Function Reference Manual.
3.3.1 I/O The RCM3000 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.
3.4 Sample Programs Sample programs are provided in the Dynamic C Samples folder, which is shown below. The various folders contain specific sample programs that illustrate the use of the corresponding Dynamic C libraries. For example, the sample program PONG.C demonstrates the output to the Dynamic C STDIO window. Two folders contain sample programs that illustrate features unique to the RCM3000. • RCM3000—Demonstrates the basic operation and the Ethernet functionality of the RCM3000.
3.5 Upgrading Dynamic C Dynamic C patches that focus on bug fixes are available from time to time. Check the Web sites • www.zworld.com/support/ or • www.rabbitsemiconductor.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.

It is recommended that you allow for an “exclusion zone” of 0.04" (1 mm) around the RCM3000 in all directions when the RCM3000 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.
Table A-1 lists the electrical, mechanical, and environmental specifications for the RCM3000. Table A-1. RabbitCore RCM3000 Specifications Feature RCM3000 RCM3010 Microprocessor Rabbit 3000 at 29.

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 RCM3000. Table A-6.
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.

C.8 Sample Programs Sample programs illustrating the use of the LCD/keypad module with the RCM3000 Series Prototyping Board are provided in the SAMPLES\RCM3000 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.
APPENDIX D. POWER SUPPLY Appendix D provides information on the current requirements of the RCM3000, and includes some background on the chip select circuit used in power management. D.1 Power Supplies The RCM3000 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 RCM3000 Series board through header J2. An RCM3000 with no loading at the outputs operating at 29.
The drain on the battery by the RCM3000 is typically 5 µA when no other power is supplied. If a 165 mA·h battery is used, the battery can last more than 3 years: 165 mA·h ------------------------ = 3.7 years. 5 µA The actual life in your application will depend on the current drawn by components not on the RCM3000 and the storage capacity of the battery. Note that the shelf life of a lithium ion battery is ultimately 10 years. The RCM3000 does not drain the battery while it is powered up normally. D.1.
APPENDIX E. PROGRAMMING CABLE Appendix E provides additional theoretical information for the Rabbit 3000™ 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.
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.
Once you establish that the programming port will never again be needed for programming, it is possible to use the programming port for additional I/O lines. Table E-1 lists the pins available for this alternate configuration. Table E-1.

APPENDIX F. MOTOR CONTROL OPTION The RCM3000/RCM3100 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.
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. Table F-1.
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.
Table F-2. Parallel Port F Registers Register Name Port F Data Register Mnemonic PFDR Bits 0:7 Port F Control Register R/W 00111000 (0x38) Value Reset Value R/W xxxxxxxx Description Read Current state of pins Write Port buffer. Value transferred to O/P register on next rising edge of transfer clock.
Table F-2.
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.
F.5 PWM Registers There are no default values on reset for any of the PWM registers. Table F-4. PWM Registers PWM LSBs Register PWL0R 10001000 (0x88) PWL1R 10001010 (0x8A) PWL2R 10001100 (0x8C) PWL3R 10001110 (0x8E) Bit(s) 7:6 Address Value Write 5:1 Description The least significant two bits for the Pulse Width Modulator count are stored These bits are ignored. 0 PWM MSB x Bit(s) 7:0 User’s Manual 0 PWM output High for single block.
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 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 coincident with the interrupt, and the interrupt (and status bits) are cleared by reading the QDCSR. Table F-5. Quadrature Decoder Registers Register Name Quad Decode Control/Status Register Mnemonic QDCSR Bit 7 (rd-only) Value Address 10010000 (0x90) Description 0 Quadrature Decoder 2 did not increment from 0xFF.
Table F-5. Quadrature Decoder Registers (continued) Register Name Quad Decode Control Register Mnemonic QDCR Bit Address = 10010001 (0x91) Description 0x Disable Quadrature Decoder 2 inputs. Writing a new value to these bits will not cause Quadrature Decoder 2 to increment or decrement. 10 Quadrature Decoder 2 inputs from Port F bits 3 and 2. 11 Quadrature Decoder 2 inputs from Port F bits 7 and 6. 5:4 xx These bits are ignored. 3:2 0x Disable Quadrature Decoder 1 inputs.
