    Yes, why not. You can capture the external pwm using eCAP peripheral and trigger the internal ePwms. Go through the eCAP peripheral and example code for detailed info.

    Hi Dharmendra,

    What you are wanting to do is possible.

    In your post, you attached Figure 7 of the current "F2802x ePWM User's Guide".  The other helpful figure is Figure 5.  This figure shows the logic that exists for synchronization in each ePWM module (and see how SYNCI and SYNCO are defined).

    Note that for ePWM1 the synchronization input comes from the GPIO mux (specifically the IO pins that have the EPWMSYNCI capability).


    Thank you,
    Brett
