19.5 Interrupts
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
*
and 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 19.6.
Note: * This function is not available in the H8S/2695.
