14.5 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 can be activated by an ADI interrupt. Having the converted data read by the DTC 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 14.6.
