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.
Port AD1 general purpose input/output data—Data Register
This register is associated with ATD1 analog inputs AN[15:8] on PAD[31:24], respectively.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
