Setting a pin to an analog input automatically disables the digital input circuitry. Weak pull-ups, if
available, are unaffected. The corresponding TRIS bit must be set to Input mode by the user, in order to
allow external control of the voltage on the pin.
Unimplemented: Read as ‘0’
ANSB<5:4>: Analog Select between Analog or Digital Function on Pins RB<5:4>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
Unimplemented: Read as ‘0’
