Data Direction Port AD — This register configures port pins AD[7:0] as either input or output.
0 Associated pin is configured as input.
1 Associated pin is configured as output.
Note: Due to internal synchronization circuits, it can take up to 2 bus cycles until the correct value is read on
Reduced Drive Port AD — This register configures the drive strength of each port AD output pin as either full
or reduced. If the port is used as input this bit is ignored.
0 Full drive strength at output.
1 Associated pin drives at about 1/3 of the full drive strength.
