Hello All,

Can the ePWM be triggered (synchronized) from the FSI_RX module without a CLB block?

    Hello Zoltan,

    There is no direct connection for FSI RX/TX signals to trigger EPWM although alterative way is to use GPIO and Input X-Bar and EPWM X-Bar to trigger epwm modules.

    GPIO pins can be flexibly mapped to be the trip-zone input and trip inputs to the trip-zone submodule and digital compare submodule. The Input X-BAR Input Select (INPUTxSELECT) register defines which GPIO pins gets assigned to be the trip-zone inputs / trip inputs.


    For more details refer to sections Digital Compare Submodule 17.11 and Configuring Device Pins 17.2 of Technical Reference Manual (TRM).
