Other Parts Discussed in Thread: TMS320F28377D

Team,

I am wondering if a CLATask can be triggered by multiple interrupts.

For my application, i am planning to trigger CLATask1 by EPWM period and zero interrupt . Is this possible?

Thanks

Rambabu,

Which device/part no. are you using?
It is possible trigger EPWM interrupt on both period and zero events.
EPWM interrupt can in turn be used as CLA trigger.
Please refer to Event Trigger Selection Register (ETSEL) to check if your device supports this feature.

Hi Bharathi

Thanks for your reply.
The device I am using is TMS320F28377D.

On CLA trigger table, i can see only EPWMxINT but there is no EPWMx_TZ.

Thanks

Ram,
That's correct. Please use EPWMxINT.
This interrupt can be generated on both period and zero events (refer ETSEL in EPWM module).
