RDRIV — Reduced Drive of I/O Lines
$000D
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
0 = All port H output pins have full drive enabled.
1 = All port H output pins have reduced drive capability.
RDPG — Reduced Drive of Port G
0 = All port G output pins have full drive enabled.
1 = All port G output pins have reduced drive capability.
RDPE — Reduced Drive of Port E
0 = All port E output pins have full drive enabled.
1 = All port E output pins have reduced drive capability.
RDPB — Reduced Drive of Port B
0 = All port B output pins have full drive enabled.
1 = All port B output pins have reduced drive capability.
RDPA — Reduced Drive of Port A
0 = All port A output pins have full drive enabled.
1 = All port A output pins have reduced drive capability.
