Hello, Your configuration of CMPSS and XBAR seem correct. Could you share your configuration of Digital Compare Event submodule, please? Please refer to Figure 17-50 in TRM for block diagram of Digital Compare Event submodule to see how EPWM X-BAR is connected to TripZone submodule. A digital compare DCAEVT1/2 or DCBEVT1/2 event is generated based on a combination of the DCAH/ DCAL and DCBH/DCBL signals as selected by the TZDCSEL register. The signals which source the DCAH/ DCAL and DCBH/DCBL signals are selected using the DCTRIPSEL register and can be either trip zone input pins or analog comparator CMPSSx signals like in your case.
