Hi Experts,

Could you explain us RAMPMAXREFS load condition? When comparator does not occurs, COMPHSTS rising edge also does not occurs,  do we have any method to generate RAMPMAXREFS load event here? Thanks.

    Shaoxing,

    RAMPSTS is loaded when the EPWM Sync signal is received, like shown in your attached diagram. 

    Are you asking if there are any other triggers for loading RAMPSTS beyond the EPWM Sync and the COMPHSTS? 

    Best Regards,
