16.5
The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion.
ADI interrupt requests can be enabled or disabled by means of the ADIE bit in ADCSR.
The DTC or 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.
The A/D converter interrupt source is shown in table 16.6.
Note: * The DMAC is not supported in the H8S/2321.
