2.4.5 Changing ADC Control Bits During Free-Running Mode not Working

If the control signals are changed during Free-Running mode, the new configuration is not ensured in the next measurement. This is valid for the ADCn.CTRLB, ADCn.CTRLC, ADCn.SAMPCTRL, ADCn.MUXPOS, ADCn.WINLT or ADCn.WINHT registers.

Work Around

Disable ADC Free-Running mode before updating the ADCn.CTRLB, ADCn.CTRLC, ADCn.SAMPCTRL, ADCn.MUXPOS, ADCn.WINLT or ADCn.WINHT registers.
