reenable EPWM after a trip zone event

I am using the TMS320F28069. I have configured one shot trip event for EPWM1 via TZFRC . That is working fine.

The problem is I want to reenable PWM later when timer1 expired.

I cleared TZCLR OST bit to restart PWM after one shot trip.

EALLOW

EPWM1.TZCLR.bit.OST = 1;

EDIS

but not working. Is there a way to reenable the PWM ?

Thanks,

Hi Gautam,
I did look at it , I have the same problem but I don't know how solve it yet.
Defining TZCLR in the ISR and not in main works but the even clear immediately .

Any idea to clear the even later ?

Thanks
Hamid
