Description
When a pin function is specified to an input port,
setting the corresponding bit to 1 turns on the input
pull-up MOS for that pin.
Description
Setting the corresponding bit to 1 specifies a pin
output type to NMOS open-drain output, while
clearing this bit to 0 specifies that to CMOS output.
