The A/D converter generates an A/D conversion end interrupt (ADI) upon the completion of A/D
conversion. ADI interrupt requests are enabled when the ADIE bit is set to 1 while the ADF bit in
ADCSR is set to 1 after A/D conversion is completed. The data transfer controller (DTC) or the
direct memory access controller (DMAC) can be activated by an ADI interrupt. Having the
converted data read by the DTC or the DMAC in response to an ADI interrupt enables continuous
conversion to be achieved without imposing a load on software.
When the DTC or the DMAC is activated by an ADI interrupt, the ADF bit in ADCSR is
automatically cleared when data is transferred by the DTC or the DMAC.
