Legend:
R = Readable bit
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 7-5
Unimplemented: Read as ‘0’.
bit 4-1
ANSG<4:1>: Analog Select between Analog or Digital Function on Pins RG<4:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
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 0
Unimplemented: Read as ‘0’.
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.
allow external control of the voltage on the pin.

bit 5
WPUG5: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
1 = Pull-up enabled
0 = Pull-up disabled
bit 4-0
Unimplemented: Read as ‘0’.
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.
