These bits select reduced drive for the associated port pins. This
gives reduced power consumption and reduced RFI with a slight
increase in transition time (depending on loading). The reduced drive
function is independent of which function is being used on a particular
port. This register is not in the map in peripheral mode.
Normal: write once; Special: write anytime except the first time. Read
anytime.
