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