Hi，

Configure the three soc respectively want to collect three sets of data to the same trigger source, according to the round robin rules should not be the first conversion SOC0, then SOC1, the last SOC2, why I debug found SOC0, SOC1, can normally enter, SOC2 can enter but after several cycles before entering it, rather than in accordance with the trigger conversion can go in once?

thank you！

    Seven,

    I'm having trouble understanding how you want the SOCs to execute.  Can you list out your desired sequence of events?  For example, the controlSUITE "adc_soc" example does:

    1. EPWM1 generates SOCA trigger
    2. ADC SOC0 -> SOC1 -> SOC2 are activated by EPWM1 SOCA trigger
    3. EOC2 generates ADC INT
    4. ADC INT activates adc_isr()
