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.
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.
Unimplemented: Read as ‘0’
ANSA<4:0>: Analog Select between Analog or Digital Function on pins RA<4:0>, 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’
WPUA5: Weak Pull-up RA5 Control bit
If MCLRE in Configuration Word 1 = 0, MCLR is disabled):
If MCLRE in Configuration Word 1 = 1, MCLR is enabled):
Unimplemented: Read as ‘0’

1 = Weak Pull-up enabled
0 = Weak Pull-up disabled
Weak Pull-up is always enabled.
