Legend:
Note 1:
2:
3:
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).
External Memory Interface I/O takes priority over all other digital and PMP I/O.
These bits are available on 80-pin devices only.
Default configuration for PMP (PMPMX Configuration bit = 1).
