When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
Global WPUEN bit of the OPTION_REG register must be cleared for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in configured as an output.
Unimplemented: Read as ‘0’
ANSB<5:0>: Analog Select between Analog or Digital Function on Pins RB<5:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
WPUB<7:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
