RabbitCore RCM2200
4.1.4 Other Inputs and Outputs
As shown in Table 1, pins PA0–PA7 can be used to allow the Rabbit 2000 to be a slave to
another processor. The slave port also uses PB2–PB5, PB7, and PE7.
PE0, PE1, PE4, and PE5 can be used for up to two external interrupts. PB0 can be used to
access the clock on Serial Port B of the Rabbit microprocessor. PD4 can be programmed
to be a serial output for Serial Port B. PD5 can be used as a serial input by Serial Port B.
PC4, PC5, PD0, PD1, PE2, PE3, and PE6 are used for internal communication with the
RealTek Ethernet interface chip.
