ATtiny13A
When Auto Triggering is used, the prescaler is reset when the trigger event occurs, as shown in
Figure 14-6
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.
Figure 14-6. ADC Timing Diagram, Auto Triggered Conversion
In Free Running mode, a new conversion will be started immediately after the conversion com-
pletes, while ADSC remains high.
