Legend: 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).
Note 1: External memory interface I/O takes priority over all other digital and PSP I/O.
2: Implemented on 80-pin devices only.
