Port AD1 general purpose input/output data
—Data Register
This register is associated with ATD1 analog inputs AN[7:0] on PAD[23:16], respectively.
When not used with the alternative function, these pins 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.
