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.
