Description
When a pin is specified as an input port, setting the
corresponding bit to 1 turns on the MOS input pull-
up for that pin.
Description
When a pin function is specified as an output port,
setting the corresponding bit to 1 specifies pin
output as open-drain and the PMOS input pull-up to
the off state. Clearing this bit to 0 specifies push-
pull output.
