4.1.1 Memory I/O Interface
The Rabbit 4000 address lines (A0–A19) and all the data lines (D0–D7) are routed inter-
nally to the onboard SRAM chips. I/0 write (/IOWR) and I/0 read (/IORD) are available
for interfacing to external devices, and are also used by the RCM4300.
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 for any reason, you must add the following line at the
beginning of your program.
#define PORTA_AUX_IO
// required to enable auxiliary I/O bus
Selected pins on Parallel Ports C, D, and E as specified in Table 2 may be used for input
capture, quadrature decoder, DMA, and pulse-width modulator purposes.
4.1.2 Other Inputs and Outputs
The PE5–PE7 pins can be brought out to header J4 instead of the STATUS and the two
SMODE pins, SMODE0 and SMODE1, as explained in Appendix A.5.
/RESET_IN is normally associated with the programming port, but may be used as an
external input to reset the Rabbit 4000 microprocessor and the RCM4300 memory.
/RESET_OUT is an output from the reset circuitry that can be used to reset other
peripheral devices.
