— = unimplemented location, read as ‘0’. Shaded cells are not used by PORTA.
Global WPUEN bit of the OPTION register must be cleared for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in configured as an output.
x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTA.
