Section 15 A/D Converter
3. When A/D conversion of all selected channels is completed, the ADF bit in ADCSR is set to 1.
4. The ADST bit is not cleared automatically, and steps [2] to [3] are repeated as long as the

If the ADIE bit is set to 1 at this time, an ADI interrupt request is generated. A/D conversion of
the first channel in the group starts again.
ADST bit remains set to 1. When the ADST bit is cleared to 0, A/D conversion stops and the
A/D converter enters wait state. If the ADST bit is later set to 1, A/D conversion starts again
from the first channel in the group.
