When Auto Triggering is used, the prescaler is reset when the trigger event occurs, as shown in
Figure 16-6
this mode, the sample-and-hold takes place two ADC clock cycles after the rising edge on the
trigger source signal. Three additional CPU clock cycles are used for synchronization logic.

In Free Running mode, a new conversion will be started immediately after the conversion com-
pletes, while ADSC remains high. See
