Section 19 ∆Σ A/D Converter
19.5
The ∆Σ A/D converter can generate an A/D conversion end interrupt request (DSADI) at the end
of A/D conversion. The ADF bit in DSADCSR is set to 1 on completion of A/D conversion, and if
the setting of the ADIE bit is 1 at this time, a DSADI interrupt request is also generated.
The DSADI interrupt can be used to activate the DMA controller (DMAC). Using the DMAC to
read the converted data in response to DSADI interrupts allows continuous conversion without
software overhead.
When performing DMA transfer in response to DSADI interrupts, setting the DTA bit in the
DMDR register of the DMA channel to 1 and placing the address of DSADDRn in DSAR enables
clearing of the ADF bit when DMA transfer is executed.
