Port AD data direction—
This bit determines whether the associated pin is an input or output.
To use the digital input function the ATD Digital Input Enable Register (ATDDIEN) has to be set to logic level “1”.
1 Associated pin is configured as output
0 Associated pin is configured as input
Port AD 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
