TMS320F28075: High Resolution Period with Deadband on up-count mode

Part Number: TMS320F28075

Hello,

Can the latest HRPWM like F2807x generate complementary high resolution PFM with deadband on up-count mode?
I tested it few years ago, but I don't remember the conclusion well. Then I want to confirm again.

Regards,
Oba

    Hi Oba,

    Yes, it is able to do that. For more information you can see the section titled "High-Resolution Period Configuration" in the device TRM. Deadband is also compatible with this mode.

    Regards,
    Kris

    Hello Kris,

    Have you tested it?
    As far as I tested, it is possible for up-down count. But it can't for up-count.
    Do you have any sample code?

    Regards,
    Oba

    Hi Oba,

    I do not have any example code for this. Which portion of the implementation seems to not be working? Do you have any waveforms you can share?

    Regards,
    Kris

    Hello Kris,

    I'm sorry that I couln't reply after that.
    This problem has not been solved yet, but unfortunately, because I'm very busy for other task now, I can't take a time to this issue.
    So I agree to close once. I may open again later.

    Thanks for your help.
