x = unknown, u = unchanged, q = value depends on condition. Shaded cells are not used by PORTB.
This buffer is a TTL input when configured as digital I/O.
This buffer is a Schmitt Trigger input when configured as the external interrupt.
This buffer is a Schmitt Trigger input when configured as the CCP2 input.
A device configuration bit selects which I/O pin the CCP2 pin is multiplexed on.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
