x = unknown, u = unchanged. Shaded cells are not used by PORTB.
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.
RC1 is the alternate assignment for CCP2 when CCP2MX is not set (all operating modes except
Microcontroller mode).
This buffer is a Schmitt Trigger input when configured as the CCP2 input.
