Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups, and
interrupt-on-change if available. The corresponding TRIS bit must be set to Input mode in order to allow
external control of the voltage on the pin.
Unimplemented: Read as ‘0’
ANS<13:8>: Analog Select bits
Analog select between analog or digital function on pins AN<13:8>, respectively.
1 = Analog input. Pin is assigned as analog input
0 = Digital I/O. Pin is assigned to port or special function.
RB<7:0>: PORTB I/O Pin bit
1 = Port pin is > V
0 = Port pin is < V
TRISB<7:0>: PORTB Tri-State Control bit
1 = PORTB pin configured as an input (tri-stated)
0 = PORTB pin configured as an output
