21.4 Interrupt and DMAC Transfer Request
The A/D converter generates an interrupt (ADI0 and ADI1) or DMAC activation signal at the end
of A/D conversion. These requests are enabled or disabled by the ADIE bit or the DMASL bit in
ADCSR.
When the DMAC is activated by an ADI interrupt, the ADF bit in the A/D control/status register
(ADCSR0 and ADCSR1) is automatically cleared to 0 when an A/D register is accessed.
