With the exception of the CMPSS signals, the ePWM X-BAR and the Output X-BAR have all of the same input signals. Due to the inputs being similar between the ePWM X-BAR, CLB X-BAR, and Output X-BAR, all X-BAR modules leverage a single set of input flags to indicate which input signals have been triggered. This allows software to check the input flags when an event occurs. See Figure 9-6 for more information. There is a bit allocated for each input signal in one of the XBARFLGx registers. The flag remains set until cleared through the appropriate XBARCLRx register.
