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:
This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.
4:
PIC16F88 devices only.
5:
The CCP1 pin is determined by the CCPMX bit in Configuration Word 1 register.
