8183D–AVR–04/11
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 16-6.
In Free Running mode, a new conversion will be started immediately after the conversion com-
pletes, while ADSC remains high. See
Figure 16-7.
