This register is used to select reduced drive for the pins associated with ports A, B, E, and K. If

enabled, the pins drive at about 1/6 of the full drive strength. The reduced drive function is

independent of which function is being used on a particular pin.

The reduced drive functionality does not take effect on the pins in emulation modes.

Reduced Drive of Port K

0 All port K output pins have full drive enabled.

1 All port K output pins have reduced drive enabled.

Reduced Drive of Port E

0 All port E output pins have full drive enabled.

1 All port E output pins have reduced drive enabled.

Reduced Drive of Port B

0 All port B output pins have full drive enabled.

1 All port B output pins have reduced drive enabled.

Reduced Drive of Ports A

0 All Port A output pins have full drive enabled.

1 All port A output pins have reduced drive enabled.
