This buffer is a Schmitt Trigger input when configured as the external interrupt.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.
PIC16F88 devices only.
The CCP1 pin is determined by the CCPMX bit in Configuration Word 1 register.
