Figure 15-5. ADC Timing Diagram, Single Conversion
When Auto Triggering is used, the prescaler is reset when the trigger event occurs. See
15-6. This assures a fixed delay from the trigger event to the start of conversion. In 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.
