Legend:
Note 1:
O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Trigger Buffer Input, TTL = TTL Buffer Input,
I2C = I²C/SMBus Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
Default assignment for CCP2 when CCP2MX Configuration bit is set.
