Port AD0 general purpose input/output data—Data Register
This register is associated with ATD0 analog inputs AN[15:8] on PAD[15:8], 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.
Port AD0 general purpose input/output data—Data Register
This register is associated with ATD0 analog inputs AN[7:0] on PAD[7:0], 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.
