Port AD0 reduced drive—Select reduced drive for output pin
This bit configures the drive strength of the associated output pin as either full or reduced. If a pin is used as input
this bit has no effect. The reduced drive function is independent of which function is being used on a particular pin.
1 Reduced drive selected (approx. 1/5 of the full drive strength)
0 Full drive strength enabled
Port AD0 pull device enable—Enable pull-up device on input pin
This bit controls whether a pull device on the associated port input pin is active. If a pin is used as output this bit has
no effect. The polarity is selected by the related polarity select register bit.
1 Pull device enabled
0 Pull device disabled
