Legend:
R = Readable bit
u = Bit is unchanged
â1â = Bit is set
W = Writable bit
x = Bit is unknown
â0â = Bit is cleared
U = Unimplemented bit, read as â0â
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-6
bit 5-4
bit 3-0
ANSC<7:6>: Analog Select between Analog or Digital Function on pins RC<3:0>, respectively(2)
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.
Unimplemented: Read as â0â
ANSC<3:0>: Analog Select between Analog or Digital Function on pins RC<3:0>, 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.
2: ANSELC<7:6> available on PIC16F/LF1829 only. Otherwise, they are unimplemented and read as â0â.

bit 7-0
WPUC<7:0>: Weak Pull-up Register bits(1, 2)
1 = Pull-up enabled
0 = Pull-up disabled
Note 1: Global WPUEN bit of the OPTION 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.
3: WPUC<7:6> available on PIC16F/LF1829 only. Otherwise, they are unimplemented and read as â0â.
