RDPH — Reduced Drive of Port H
RDPE — Reduced Drive of Port E
RDPB — Reduced Drive of Port B
RDPA — Reduced Drive of Port A
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.
