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