Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-6
bit 5-0
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⁽¹⁾. Digital input buffer disabled.
Note 1: 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.

WPUB<7:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
Note 1: Global WPUEN bit of the OPTION_REG register must be cleared for individual pull-ups to be enabled.
2: The weak pull-up device is automatically disabled if the pin is in configured as an output.
