Part Number: TMS320F28335

Tool/software: Code Composer Studio

The AD module is in dual-sequencer mode ，SEQ1 and SEQ2 operate as two 8-state sequencers，

I cannot trigger seq2 to start the conversion when SEQ1 starts the conversion, or I cannot trigger SEQ1 to start the conversion when seq2 has already started the conversion

user6083218,

Can you provide some more information about how you expect the system to behave? For example, what triggers are you trying to use?

How do you determine if the SEQn is triggered or not? Are the interrupts serviced independently?

SEQ1 and SEQ2 are triggered by software（software SOC），

user6083218,

I suspect that CONT_RUN=1 might be contributing to your issue. In that mode, the first ADC sequencer is configured to convert continuously as soon as its SOC trigger is asserted, which may block the second SOC trigger to the other sequencer.
