22.7
The A/D Converter in the PIC18F47J53 family of
devices includes a self-calibration feature, which com-
pensates for any offset generated within the module.
The calibration process is automated and is initiated by
setting the ADCAL bit (ADCON1<6>). The next time
the GO/DONE bit is set, the module will perform an off-
set calibration and store the result internally. Thus,
subsequent offsets will be compensated.
Example 22-1 provides an example of a calibration
routine.

The calibration process assumes that the device is in a
relatively steady-state operating condition. If A/D
calibration is used, it should be performed after each
device Reset or if there are other major changes in
operating conditions.
