Interrupt when multi calibration factor occurs
The calibration of the four factors to carry out the calibration is different respectively. Therefore, state the calibration
of another is started during the conduct of certain calibration, the conflict occurs.
If the calibration different conditions occur in the middle of the calibration, calibration being performed to stop, a new
calibration is carried out from the beginning.
The interrupt by finishing the first factor’s calibration is set, and the interrupt by the new factor’s calibration is set
too.
Calibration factor α occurs.
Calibration factor β occurs.
ADC value
Start calibration by factor α.
Start calibration by factor β.
Interrupt calibration finish of factor α.
Interrupt calibration finish of factor β.
