Hi, [quote userid="315989" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1418819/tms320f28379d-soc0-and-soc1-issue-on-adc-a/5440536#5440536"]In that case, how does the first code above, which only uses SOC0, work, even though I'm not restarting a conversion using the ADCSOCFRC1 register?[/quote] This is a good point, I cannot see from your code how the SOCs are being triggered again. How did you configure the SOCs to be triggered? With your code it cannot be only software triggered.

Could this create a conflict since ADCINT1 is set to 1 at the end of the conversion?[/quote] Oh ok, this explains the above.

Your problem is likely caused by the timing of setting and clearing the ADCINT flag, and this example will show you how to handle that by setting up the ADC in continuous conversion mode.
