Operation example 2: Group A trigger input during group B rescan, with rescan setting
Figure 26.17 shows an example when a group A trigger is input during rescan operation on group B.
If a group A trigger is input, scan for group A starts even while rescan operation is in progress. Scan for group B starts
after scan for group A is completed.
Operations of the ADCSR.ADST bit, storing to the A/D conversion result in the A/D data register (ADDRy), and
interrupt requests are the same as example 1.
