Description
Reserved
These bits are read as an undefined value and
cannot be modified.
When a pin is specified as an input port, setting the
corresponding bit to 1 turns on the input pull-up MOS
for that pin.
Description
Reserved
These bits are read as an undefined value and
cannot be modified.
When a pin is specified as an output port, setting the
corresponding bits to 1 specifies pin output to open-
drain and the input pull-up MOS to the off state.
Clearing these bits to 0 specifies that to push-pull
output.
