I = input

O = output

I/O = input/output

P = power

— = Not used

TTL = TTL input

ST = Schmitt Trigger input

This buffer is a Schmitt Trigger input when configured as an external interrupt.

This buffer is a Schmitt Trigger input when used in Serial Programming mode.

This buffer is a Schmitt Trigger input when configured as a general purpose I/O and a TTL input when used in the Parallel

Slave Port mode (for interfacing to a microprocessor bus).

This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.

Pin location of CCP2 is determined by the CCPMX bit in Configuration Word Register 1.
