TI F28379D Error on event filter of ePWM

Hi！

I am trying to set the blank width register of event filter in the ePWM to about 20000. But the error occurs as shown in the picture. But according to the user manual form TI, the corresponding register is 16 bits, so it can be set to the the desired value. So is this a bug or am I not using this ePWM correctly?

Thanks a lot!

Thank you very much for pointing this out to us. It is a bug. For ePWM Type4, which is the case for the processor TI F28379D, the blanking width is 16-bit long.

We will be fixing this bug in the future release. Apologies for the inconvenience caused.

Could you let us know the MATLAB release you got this error in? If possible we will try to backport the fix to older releases as well.

Hi,

Thank you for your reply. We are currently using MATLAB 2020a and 2020b, and we have found this error in both releases at least, look forward to a further fix!
