TMS320F280049: CLA: How to using software to trigger Background task one time and background task will operate continuously ?

Hi experts, 

According to the MCTLBGRND Register Field Descriptions: 

The MSTOP instruction will clear the BGSTART bit. On the other hand, the following figs show the background task's assembly codes, it can be found that MSTOP instruction will be added in the end of the background task. 

So we need to trigger the CLA background task again via API of CLA_startBackgroundTask(CLA1_BASE);

I want to know if there is a way to avoid the MSTOP instruction in the end of the background task so that the SW can trigger background task just one time and background task will operate continuously. 

Best Regards, 

Will
