The A/D Converter has a unique feature of being able
to operate while the device is in Sleep mode. To oper-
ate 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.

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.
Each port pin associated with the A/D Converter can be
configured as an analog input, or as a digital I/O. The
ADRESH and ADRESL registers contain the result of the
A/D conversion. When the A/D conversion is complete,
the result is loaded into the ADRESH:ADRESL register
pair, the GO/DONE bit (ADCON0 register) is cleared and
the A/D Interrupt Flag bit, ADIF, is set. The block diagram
of the A/D module is shown in Figure 19-1.
