Legend: 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).
Note 1: Alternate PMP configuration when the PMPMX Configuration bit = 0; available on 80-pin devices only.
