TMS320F28335: EPWM

Part Number: TMS320F28335

How can I disable and enable the EPWM modules with some high-low logic?

Is there any single sentence instruction for it?

Well I am using Dead-band generator so I also wanted to disable PWMxB(LOW).

I have a predefined register which gives me the command to start or to stop the EPWMs but I didn't find the proper method to do it, Can you suggest any?

Hi Kaushik,

One way to implement something like this would be to use the trip zone submodule. There is the TZFRC register which allows you to force a trip zone event (one-shot). You can configure TZA and TZB bits to make EPWMxA and EPWMxB go low upon the trip. When you are ready to re-enable the output you can remove the forced trip event and clear the one-shot flag.

Best Regards,

Marlyn
