The ANCON0 and ANCON1 registers are used to
configure the operation of the I/O pin associated with
each analog channel. Setting any one of the PCFG bits
configures the corresponding pin to operate as a digital
only I/O. Clearing a bit configures the pin to operate as
an analog input for either the A/D Converter or the com-
parator module; all digital peripherals are disabled, and
digital inputs read as ‘0’. As a rule, I/O pins that are
multiplexed with analog inputs default to analog
operation on device Resets.

ANCON0 and ANCON1 are shared address SFRs, and
use the same addresses as the ADCON1 and
ADCON0 registers. The ANCON registers are
accessed by setting the ADSHR bit (WDTCON<4>).
See Section 5.3.5.1 “Shared Address SFRs” for
more information.
