bit 0

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 7-4

bit 3-0

Unimplemented: Read as ‘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.

WPUC<5:0>: Weak Pull-up Register bits

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.
