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 7-4
bit 3
Unimplemented: Read as ‘0’
ANS3: Analog Select bits
Analog select between analog or digital function on pins AN<7:0>, respectively.
(1)
1= Analog input. Pin is assigned as analog input
.
0= Digital I/O. Pin is assigned to port or special function.
bit 2
bit 1
Unimplemented: Read as ‘0’
ANS1: Analog Select Between Analog or Digital Function on Pins GP1
(1)
1= Analog input. Pin is assigned as analog input.
0= Digital I/O. Pin is assigned to port or special function.
bit 0
ANS0: Analog Select Between Analog or Digital Function on Pins GP0
0= Digital I/O. Pin is assigned to port or special function.
1= Analog input. Pin is assigned as analog input.

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.
