FAQ
How to read ADC conversion results using PDMA? Issue Date:2015-04-23
When A/D conversion is finished, the converted result is loaded into ADDR register and the VALID bit is set to ‘1’. If the PTEN bit in ACDR is set to ‘1’, the ADC controller will generate PDMA request (P_nDRQ) for data transfer. Having the converted result read by PDMA in response to P_nDRQ enables continuous A/D conversion to be achieved without CPU intervention.
