TMS320F280049: Can we modify EPWM action when ITRAP happens?

Part Number: TMS320F280049

Dear Experts,

I ask this for our customer.

Now customer want to know if we can do some code processing in ITRAP. Customer testing found that if ITRAP occurs, one of EPWM channel will be pulled low and another EPWM channel will be pulled high, which will damage the customer's board. They want to know whether the action of the device pin can be modified in the code when ITRAP occurs?

In addition, the customer also wants to know how the CPU behaves when ITRAP occurs?

Thank you for your support.

Best regards,

Julia

    Hi Julia,

    ITRAP is like any other interrupt handler and user should be able to write any code inside it.

    As mentioned in last point, it's like any other interrupt handler so it'll execute the ITRAP handler code. You can find additional detail about ITRAP here.
