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.
