TMS320F280049: Questions regarding DMA's trigger signal

Hi expert,

From our TRM, there are two signals "Peripheral DMA Trigger" and "Software Trigger" input to an and gate. My question is how long will these signals last once being triggered?

Thanks

    Sheldon,

    CONTROL.PERINTFRC always reads 0 and will never read as '1'. PERINTFLG gets cleared when DMA burst starts (or) when PERINTCLR bit is set.

    Peripheral DMA trigger events doesn't have a corresponding flag bit. So, your question doesn't apply here.

    Regards,
