      2. Configure the output PWM frequency through the API EPWM_tbPwmFreqCfg
      3. If synchronization is enable, then configure the synchronization through the API EPWM_tbSyncEnable else disable synchronization through the API EPWM_tbSyncDisable

      5. Set the emulation mode through the API EPWM_tbSetEmulationMode
   2. Counter comparator

   4. Chopper
      1. If chopper is enabled
         1. Configure chopper through the API EPWM_chopperCfg
