Hi May,

I took a look at the doc attached and have some questions below.

1. Could you ask customer to draw a pic with the expected waveform he would like to see? for example, the current, epwm counter, epwm comparator(CMPA/Zero etc).

2. I can not see where exactly the zero point of EPWM so I can not tell what happens then.

3. Also the comparator output does not seems correct. Once the current decreases, why the CMPSS output is still high? Is there another threshold?

Regards,

Chen
