ANS<7:0>: Analog Select bits
Analog select between analog or digital function on pins AN<7:0>, respectively.
1 = Analog input. Pin is assigned as analog input.
0 = Digital I/O. Pin is assigned to port or special function.
bit 7
Unimplemented: Read as ‘0’
ANS<11:8>: Analog Select bits
Analog select between analog or digital function on pins AN<11:8>, respectively.

must be set to Input mode in order to allow external control of the voltage on the
pin. Port reads of pins configured assigned as analog inputs will read as ‘0’.
