There are two trip zone configuration dialogs: one for older TI parts; the other for newer TI parts:
•ePWM TRIPSEL Config: For older TI parts. This dialog uses only GPIO inputs to turn off the PWM. See Texas Instruments documentation for more information.
•EPWM XBAR Mux Config: For newer TI parts. This dialog uses a variety of internal and external signals to trip PWM output into fault mode. The EPWMXBAR is an OR gate with up to 31 possible and configurable inputs. When using this newer TI parts configuration, INPUTXBARs can be routed into the EPWMXBAR, and if selected, a GPIO must be allocated for each INPUTXBAR selected. The GPIOs will be configured as inputs. See Texas Instruments documentation for more information.
