13. High Speed A/D Converter

Interrupts
The high speed A/D converter generates an A/D conversion end interrupt (ADI) upon completion
of A/D conversions. The ADI interrupt request can be enabled or disabled by the ADIE bit of the
ADCSR.
The DMAC can be activated by ADI interrupts. When converted data is read by the DMAC upon
an ADI interrupt, consecutive conversions can be done without software responsibility.
Table 13.9 lists the high speed A/D converter interrupt sources.
During scan mode, if the ADIE bit is set to 1, A/D conversion is temporarily suspended
immediately when the ADF flag is set to 1. A/D conversion is restarted when the ADF flag is
cleared to 0.
When the DMAC is activated by an ADI interrupt, the ADF flag is cleared to 0 when the final
specified data register is read.
