Power Management Controller (PMC)
ADC12B: Saturation
PMC: Main Oscillator Frequency selection if the Main On-chip RC Oscillator is OFF
When the ADC12B works in saturation (measurements below 0V or above ADREF) the results
may be erratic, the value deviation can be around 30 LSB to the expected data.
None.
When the 4/8/12 MHz RC Oscillator is off, the frequency selection (MOSCRCF bitfield in
CKGR_MOR) can not be changed. The register can be written but the modification to
MOSCRCF will not be taken into account.
Modify MOSCRCF while 4/8/12 MHz RC Oscillator is on (MOSCREN = 1).
4. Use wait mode instead of Backup mode.
