Port 3 (P37–P31)
The CCP wakes up with the 8 bits of Port 2 configured as inputs with open-drain
outputs.
Port 2 also has an 8-bit input OR and an AND gate that can be used to wake up
the part. P20 can be programmed to access the edge-selection circuitry.
Port 3 is a 7-bit, CMOS-compatible port (see
fixed inputs (P33–P31) and four fixed outputs (P37–P34) and can be configured
under software control for Input/Output, Interrupt, Port handshake, Data Memory
functions, and output from the counter/timers. P31, P32, and P33 are standard
CMOS inputs; outputs are push-pull.
Two on-board comparators process analog signals on P31 and P32 with refer-
ence to the voltage on Pref1 and P33. The analog function is enabled by program-
