TMS320F280025C: TMS320F280025C, EPWM, Only use A side

Hello.
Please forgive my poor English notation.

I am using the ePWM function of the TMS320F280025C to generate PWM waves with variable duty ratio.
So, is it possible to disable the B side (EPWMxB) when all I want to use is the A side (EPWMxA)?
If it is possible, how do I set it up using the .syscfg file?

    Hi,

    Thanks for contacting the E2E forums!

    Yes, definitely you can do that. Please don't configure the action qualifier for EPWMxB. You won't see any output on the B terminal. Also, make sure that the dead band is disabled.

    This should give you the desired output waveform.

    Thanks,

    Aditya
