TMS320F280049: PWM1A/1B asynchronized output

Hitoshi Sugawara

Hi Champs,

Could you please give ideas to create the PWM1A/1B outputs which are shown in the attached file?

A customer would like to set Toff_A, Ton_A, Toff_B and Ton_B Individually.
I was not able to find any method for the configuration in AQ nor ET.

Thank you for your kind help.
Best regards,
Hitoshi

The attachment didn't go through for some reason. I'm attaching a .doc file.

You can use combination of deadband and CMPA/B values to achieve the above configuration. Please have a look and let me know if you have any additional questions.
