Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 0
Unimplemented: Read as ‘0’
ANS3: Analog Select Between Analog or Digital Function on Pin GP4
1 = Analog input. Pin is assigned as analog input(1).
0 = Digital I/O. Pin is assigned to port or special function.
Unimplemented: Read as ‘0’
ANS1: Analog Select Between Analog or Digital Function on Pin GP1
1 = Analog input. Pin is assigned as analog input.(1)
0 = Digital I/O. Pin is assigned to port or special function.
ANS0: Analog Select Between Analog or Digital Function on Pin GP0
0 = Digital I/O. Pin is assigned to port or special function.
1 = Analog input. Pin is assigned as analog input.(1)
Note 1: Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups, and interrupt-on-
change if available. The corresponding TRIS bit must be set to Input mode in order to allow external control of
the voltage on the pin.

ANS<3:0>: Analog Select Between Analog or Digital Function on Pins GP4, GP2, GP1, GP0, respectively.
1 = Analog input. Pin is assigned as analog input(1).
0 = Digital I/O. Pin is assigned to port or special function.
Note 1: Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups, and interrupt-on-
change if available. The corresponding TRIS bit must be set to Input mode in order to allow external control of
the voltage on the pin.
