Bits 22:16 CALFACT_D[6:0]: Calibration Factors in differential mode
These bits are written by hardware or by software.
Once a differential inputs calibration is complete, they are updated by hardware with the calibration
factors.
Software can write these bits with a new calibration factor. If the new calibration factor is different
from the current one stored into the analog ADC, it will then be applied once a new differential
calibration is launched.
Note: Software is allowed to write these bits only when ADEN=1, ADSTART=0 and JADSTART=0
(ADC is enabled and no calibration is ongoing and no conversion is ongoing).
Bits 15:7 Reserved, must be kept at reset value.
Bits 6:0 CALFACT_S[6:0]: Calibration Factors In Single-Ended mode
These bits are written by hardware or by software.
Once a single-ended inputs calibration is complete, they are updated by hardware with the
calibration factors.
Software can write these bits with a new calibration factor. If the new calibration factor is different
from the current one stored into the analog ADC, it will then be applied once a new single-ended
calibration is launched.
Note: Software is allowed to write these bits only when ADEN=1, ADSTART=0 and JADSTART=0
(ADC is enabled and no calibration is ongoing and no conversion is ongoing).
