Bits 31:7 Reserved, must be kept at reset value.
Bits 6:0 CALFACT[6:0]: Calibration factor
These bits are written by hardware or by software.
– Once a 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 is then applied once a new conversion is
launched.
– Just after a calibration is complete, DATA[6:0] contains the calibration factor.
Note: Software can write these bits only when ADEN=1 (ADC is enabled and no calibration is ongoing
and no conversion is ongoing).
