two additional internal voltage reference selections:
2.048V and 4.096V.
The A/D Converter can uniquely operate while the
device is in Sleep mode. To operate in Sleep, the A/D
conversion clock must be derived from the A/D’s
internal RC oscillator.
The output of the sample and hold is the input into the
converter, which generates the result via successive
approximation.

AN15 through AN12 and AN 20 through AN23 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.

Each port pin associated with the A/D Converter can be
configured as an analog input or a digital I/O. The
ADRESH and ADRESL registers contain the result of
the A/D conversion. When the A/D conversion is com-
plete, the result is loaded into the ADRESH:ADRESL
register pair, the GO/DONE bit (ADCON0<1>) is
cleared and the A/D Interrupt Flag bit, ADIF (PIR1<6>),
is set.
A device Reset forces all registers to their Reset state.
This forces the A/D module to be turned off and any
conversion in progress is aborted. The value in the
ADRESH:ADRESL register pair is not modified for a
Power-on Reset. These registers will contain unknown
data after a Power-on Reset.
The block diagram of the A/D module is shown in
Figure 23-4.
