I  am  designing    a  controler   with   epwm   ,  when   controler   begains   to   work,    there  are     four     couples    epwms   (EPWM1-EPWM8),  start   to   work  alternately,   I   have    two   questions   to    ask:   one    

for     please   tell  me     how  to    interruppt    pwm    signals   output      anytime   when   it  works ?        another  for       how  to    achieve       synchro?     it   normal   works  to  use   two   channals     PWM  signals   at    any   

moment.      whole   system   have   eight     channals        PWM     signals.

    For synchronizing the F28379D ePWM modules please see the Figure 14-7 (Time-Base Counter Synchronization Scheme) on page 1689 in the F28379D Technical Reference Manual:

    www.ti.com/lit/SPRUHM8

    Also, I would like to reference two additional resource that you might find helpful. First, please review the video "Getting Started with the C2000 ePWM Module" at:

    training.ti.com/getting-started-c2000-epwm-module

    Second, then review the F28379D multi-day workshop materials at:

    processors.wiki.ti.com/.../C2000_Multi-Day_Workshop

    See module 7 for the ePWM. Here you will find information on interrupts, too.

    I hope this helps. If this answers your question, please click the green "Verified Answer" button. Thanks.
