Figure 12-303 shows how the trip-zone (TZ) submodule fits within the EPWM module. Each EPWM module is connected to six TZ signals ( TZ0 to TZ5) that are sourced from the GPIO MUX. These signals indicates external fault or trip conditions, and the EPWM outputs can be programmed to respond accordingly when faults occur. See EPWM Integration to determine the number of trip-zone pins available for the device.
The key functions of the trip-zone submodule are:
For each EPWMx module, 6 tripzone input events are supported ( EPWMx_TRIP_TZ[5:0]). Each tripzone input for all EPWMx modules are tied to a common tripzone input pin, so that any EPWMx can be triggered by any of the six tripzone inputs.
