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.
Valid for PIC18F8525/8621 devices in all operating modes except Microcontroller mode when CCP2MX is
not set. RC1 is the default assignment for ECCP2/PA2 when CCP2MX is set in all devices; RE7 is the
alternate assignment for PIC18F8525/8621 devices in Microcontroller mode when CCP2MX is clear.
This buffer is a Schmitt Trigger input when configured as the ECCP2 input.
x = unknown, u = unchanged. Shaded cells are not used by PORTB.
