ANSEL — ANALOG SELECT REGISTER (ADRESS: 91h) (PIC16F676 ONLY)
ANS<7:0>: 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.
Note 1: Setting a pin to an analog input automatically disables the digital input circuitry,
