14. Mid-Speed A/D Converter ⎯ SH7016, SH7017 ⎯
14.5 Interrupt
The mid-speed A/D converter generates an A/D conversion end interrupt (ADI) on completion of
A/D conversion. ADI interrupt requests can be enabled or disabled by means of the ADIE bit in
ADCSR.
The DMAC can be activated by an ADI interrupt. Having converted data read by the DMAC by
means of ADI interrupts allows continuous conversion to be carried out without imposing a load
on the software.
The mid-speed A/D converter's interrupt source is summarized in table 14.5.
When the DMAC are activated by an ADI interrupt, the ADF flag of ADCSR is cleared to 0 by
register access of A/D.
