TMS320F28379D: CLA Trigger by PWM interrupt

Jay

Part Number: TMS320F28379D


Hello,

I need one clarification regarding CLA task trigger by PWM interrupt.

Requirement: I want to trigger CLA task by PWM interrupt but don't want to map any ISR to it.

1) Can we do CLA triggering by PWM interrupt and not map it to any ISR in PIetable. 

2) As Pietable filled with some garbage address and if we enabling interrupt only and not mapping it to any valid ISR in pietable, will it create any impact on the entire software? 

Regards,

    Hi Jay,

    To clarify, are you asking if you can have a CLA task without CLA ISR? Or are you asking if you can have an EPWM interrupt without an EPWM ISR? Can you explain why you are trying to develop without an interrupt ISR? Keep in mind if you are using an EPWM interrupt to trigger a CLA task, the EPWM interrupt flag will need to be cleared to allow for repeated EPWM interrupts to be triggered (the clearing of the EPWM interrupt flag is usually done in the respective PWM ISR). Are you only needing to trigger the CLA task once?

    Best Regards,

    Allison
