How to use SVENABLE bit in F2812 chip

Dear HiSupport:

          I would like to set SVENABLE = 1 in COMCONA, 

          I would like to use chip build-in function as much as it's provided. 

         but I find less useful material to let me understand how to use such function.

         more cases which i could find are set SVENABLE =0.

Best Regards

Fred
