SDK15.2 Operational issues between FDS and PPI ADC

Hi Nordic,

    Does FDS affect PPI ADC acquisition when writing data? The test found that once the FDS is written to the data, the ADC data returned by the PPI ADC is fixed.

1.The acquired AD data is correct before the FDS write operation.

2.After the FDS write operation, the acquired AD data will have a fixed interval.

I am using SDK15.2 and PPI to trigger the ADC to collect data. Is there a conflict with FDS writing data?Please help answer, thank you!
