O = Output, I = Input, 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).
Default assignments for P1B/P1C and P3B/P3C when ECCPMX Configuration bit is set (80-pin devices only).
External Memory Interface I/O takes priority over all other digital and PMP I/O.
Available on 80-pin devices only.
Alternate assignment for ECCP2/P2A when ECCP2MX Configuration bit is cleared (all devices in Microcontroller mode).
Default configuration for PMP (PMPMX Configuration bit = 1).
