Hello, I'm struggling with the analog comparator module in 28069.
I want to make ePWM output high for constant time, at the rising edge of the analog comparator output like UCC28061.
However, if the output of analog comparator remained high, DCxEVT is produced continuously and ePWM output also remained high.
So, in ISR of DCxEVT, I tried to disable DCAH event (comparator high) when DCAH flag is 1, and then enalbe DCAH event when DCAL event occurs (comparator low).
However, ISR takes too long time to get proper result, since the system is required to operate as fast as up to 100kHz.
In this case, could you tell me how I can solve this problem?
Is it possible to get DCxEVT at the rising edge of analog comparator output without using additional ISRs??
Actually, I would like to implement CRM boost PFC converter with 28069.
Best regards,
