TMS320F280025: CMPSS interrupt

Part Number: TMS320F280025

Dear C2000 expert,

I couldn't find any example of how to configure CMPSS to generate interrupt, can you share some suggestions? Thanks...

    Hi,

    There is no interrupt assigned to CMPSS. It has two oututs wherein one is routed to external pin and another is routed to EPWM XBAR which can be used to trip a PWM signal. Can you share more details on the usecase and then we can see if this can be supported through CMPSS?

    Thanks

    Dear Vasudha,

    Thanks for supporting on this.

    What I want is that using a CMPSS to get the compare results of 2 external analog signals. When one signal less than/ above another signal, then trip a interrupt, and turn on a IO in a specific time (5us) in ISR.

    As you mentioned the output of CMPSS can be routed to external pin, can I connect it to XIN1/2/3/4 through INPUT X-Bar to assert a interrupt?
