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 7-0

ANS<7:0>: Analog Input Function Select bits

Correspond to pins, AN<7:0>.

1 = Analog input

0 = Digital I/O

Note 1:

2:

Setting a pin to an analog input disables the digital input buffer. The corresponding TRIS bit should be set

for an input and cleared for an output (analog or digital). The ANSx bits directly correspond to the ANx pins

(e.g., ANS0 = AN0, ANS1 = AN1, etc.). Unused ANSx bits are read as ‘0’.

ANS7 through ANS5 are available only on PIC18F4331/4431 devices.

1 = Analog input

0 = Digital I/O

Setting a pin to an analog input disables the digital input buffer. The corresponding TRIS bit should be set

for an input and cleared for an output (analog or digital). The ANSx bits directly correspond to the ANx pins

(e.g., ANS8 = AN8, ANS9 = AN9, etc.). Unused ANSx bits are read as ‘0’.

ANS8 is available only on PIC18F4331/4431 devices.
