Description
Legend:
PWR = Power Supply, O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input,
TTL = TTL Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
TTL = TTL Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
Note
1:
Alternate assignment for ECCP2 when CCP2MX Configuration bit is cleared (all devices in Microcontroller mode).
2:
Implemented on 80-pin devices only.
