    ADC Performance During Flash Write

    BrCo_4643431

      Hello,

       

      I have noticed a problem with ADC accuracy during a write to flash. I have the CM0+ executing a partially-blocking flash write. The CM4, meanwhile, is sampling an input signal at a constant rate. During the flash write the sampling seems to have one or two incorrect samples. I suspect it could be a power supply problem, as the ADC is referenced to the 3V3 VDD rail. Has anyone had issues with using these two features at the same time?
