17.5
The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion.
Setting the ADIE bit to 1 when the ADF bit in ADCSR is set to 1 after A/D conversion is
completed enables ADI interrupt requests. The data transfer controller (DTC)* and DMA
controller (DMAC) can be activated by an ADI interrupt. Having the converted data read by the
DTC* or DMAC in response to an ADI interrupt enables continuous conversion to be achieved
without imposing a load on software.
Note: * Only possible in unit 0.
