TMS320F280039C: CLA task1 to trigger CLA task2 without CPU during runtime?

Part Number: TMS320F280039C

Dear Champs,

I am asking this for our customer.

Is it possible to trigger a CLA task from another CLA task directly without interrupting CPU?

1) Is it possible to use CLA task1 completion to trigger CLA task2 by hardware?

2) Is it possible to use CLA task1 to trigger CLA task2 by software?

If yes, how to do that?

3) What if CLA task1 writes to a peripheral that CLA can access and then use it to trigger CLA task2? Do you think it makes sense?

For example, 

CLA task1 to set EPWMx.ETFRC and then use EPWMx to trigger task2?

Any concern here?
