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).
External memory interface I/O takes priority over all other digital and PSP I/O.
Available on 80-pin devices only.
