Port AD0 reduced drive—Select reduced drive for Port AD0 outputs
This register configures the drive strength of Port AD0 output pins 7 through 0 as either full or reduced independent
of the function used on the pins. If a pin is used as input this bit has no effect.
1 Reduced drive selected (approx. 1/5 of the full drive strength).
0 Full drive strength enabled.
Port AD0 pull device enable—Enable pull devices on input pins
These bits configure whether a pull device is activated, if the associated pin is used as an input. This bit has no effect
if the pin is used as an output. Out of reset no pull device is enabled.
1 Pull device enabled.
0 Pull device disabled.
