bit 7-0:
ANS<7:0>
: Analog Select bits
Analog select between analog or digital function on pins AN<7:0>, 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.
Port reads of pins configured assigned as analog inputs will read as ‘
0
’.
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
