bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-6

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.

bit 5-4

Unimplemented: Read as ‘0’

bit 3-0

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.

ANSELC<7:6> available on PIC16F/LF1829 only. Otherwise, they are unimplemented and read as ‘0’.

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

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.

The weak pull-up device is automatically disabled if the pin is in configured as an output.

WPUC<7:6> available on PIC16F/LF1829 only. Otherwise, they are unimplemented and read as ‘0’.
