iMX7D SDMA data transfer stop immediately?

Hi,

 

I want to transfer the output result converted by ADC to the memory by SDMA.
Set the Channel Stop / Channel Status (SDMAARM_STOP_STAT) bit to stop data transfer
The ADC peripheral clock has stopped.
Then, in rare cases, it seems that an abort exception occurs when transferring data.
I think this is because the ADC was accessed because the SDMA data transfer did not stop immediately.
Is it necessary to stop the data transfer and then wait?
