Legend:
Note 1:
2:
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).
Alternate assignment for ECCP2/P2A when the CCP2MX configuration bit is cleared (Extended Microcontroller mode,
80-pin devices only). Default assignment is RC1.
All other pin functions are disabled when ICSP or ICD are enabled.
