Legend: TTL = TTL input, ST = Schmitt Trigger input
Note 1:
This buffer is a Schmitt Trigger input when configured as the external interrupt.
2:
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
3:
RC1 is the alternate assignment for CCP2 when CCP2MX is not set (all operating modes except
Microcontroller mode).
4:
This buffer is a Schmitt Trigger input when configured as the CCP2 input.
