O = output
TTL = TTL input
I/O = input/output
ST = Schmitt Trigger input
P = power
Note 1: This buffer is a Schmitt Trigger input when configured as an external interrupt.
2: This buffer is a Schmitt Trigger input when used in Serial Programming mode.
3: 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).
4: This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.
5: Pin location of CCP2 is determined by the CCPMX bit in Configuration Word Register 1.
