9 Global Load Differences

The global load feature allows for simultaneous loading of several shadow to active registers triggered by hardware or software events. The MCPWM global load feature differences when compared to EPWM are as follows:

  • SYNCIN signal cannot be used to trigger global load
  • Global load prescaler counter removed from MCPWM
  • Global load for action qualifier continuous software force removed
  • Global load for CMPC / CMPD removed
  • Global load for DBCTL removed
