ANSC7 ANSC6 — — ANSC3 ANSC2 ANSC1 ANSC0

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

1 = Analog input. Pin is assigned as analog input

(1)

. Digital input buffer disabled.

0 = Digital I/O. Pin is assigned to port or digital special function.

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

1 = Analog input. Pin is assigned as analog input

(1)

. Digital input buffer disabled.

0 = Digital I/O. Pin is assigned to port or digital special function.

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.

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 7-0 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_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.
