31.3.3.1 Operation Modes

The ADC supports differential and single-ended conversions. This is configured in the CONVMODE bit in the ADCn.CTRLA register.

The operation modes can be split into two groups:

Single conversion of one sample per trigger
Accumulated conversion of n conventions per trigger, the result is accumulated

The accumulated conversion utilizes 12-bit conversions and can be configured with or without truncation of the accumulated result. The accumulator is always reset to zero when a new accumulated conversion is started.
