Low Latency Mode Must Be Set Before Changing ADC Configuration

If using the low latency mode in the ADC, the initialization delay does not start for settings configured before the Low Latency (LOWLAT) bit in the Control A (ADCn.CTRLA) register. This may result in a conversion starting before the initialization time has ended and give a corrupt result.

Work Around

Enable the low latency bit (LOWLAT) in the Control A (ADCn.CTRLA) register at the start of ADC initialization before configuring any other register in the ADC.
