PIC18F87K22 FAMILY
The ANCONx registers are used to configure the
operation of the I/O pin associated with each analog
channel. Clearing an ANSELx bit configures the
corresponding pin (ANx) to operate as a digital only I/O.
Setting a bit configures the pin to operate as an analog
input for either the A/D Converter or the comparator
module, with all digital peripherals disabled and digital
inputs read as ‘ 0 ’.

AN15 through AN12 and AN23 to AN20 are implemented only on 80-pin devices. For 64-pin devices, the
corresponding ANSELx bits are still implemented for these channels, but have no effect.
ANSEL<7:0>: Analog Port Configuration bits (AN7 and AN0)
1 = Pin is configured as an analog channel; digital input is disabled and any inputs read as ‘ 0 ’
0 = Pin is configured as a digital port
ANSEL<15:8>: Analog Port Configuration bits (AN15 through AN8)
1 = Pin is configured as an analog channel; digital input is disabled and any inputs read as ‘ 0 ’
0 = Pin is configured as a digital port

As a rule, I/O pins that are multiplexed with analog
inputs default to analog operation on any device Reset.
