F29H850TU: Pin issue for EPWM6 - Sysconfig

Part Number: F29H850TU

Hi, I'm trying to use several EPWM instances together. However, when I initialise EPWM6 it throws an error of pin conflict X1,X2. The other pin it shows is already in use for GPIO input. However, my application only needs an internal input from EPWM to the CLB and the output is taken from an OUTPUTXBAR initlialised pin. Could you please assist on this on an urgent basis?

Thank you

    Hi Syed,

    Can you try to Configure the CLB input via EPWMXBAR (not via a physical pin), since you only need the internal input?

    So for example -> EPWMXBAR_configureInput(EPWMXBAR_INPUT_EPWM6, EPWMXBAR_SOURCE_EPWM6_A);

    This routes the internal EPWM‑6 event into the CLB without touching any external pin.

    Thanks,

    Ira
