Legend:
Note 1:
O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Trigger Buffer Input, TTL = TTL Buffer Input,
I²C = I²C Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
Default assignment for ECCP2 when the CCP2MX Configuration bit is set.
