LAUNCHXL-F28379D: Identification of an OST interrupt

Part Number: LAUNCHXL-F28379D


Tool/software:

Hello,

I use 3 CMPSS to generate 3 TRIP signals through EPWM XBAR: TRIP4, TRIP5 and TRIP7.

These 3 TRIP signals enter into the Digital Compare Submodule of an EPWM module, which generates DCAEVT1.

DCAEVT1 is one of the sources of the One Shot Trip Zone, and I use the EPWM TZ interrupt.

In the TZ ISR, I can identify:

- the  event (OST) that caused the interrupt thanks to EPWM_getTripZoneFlagStatus function

- the source (AEVT1) that caused the OST thanks to the EPWM_getOneShotTripZoneFlagStatus function

But, what is the right way to identify the TRIP signal that caused the DCAEVT1 event ?

Thank you
