TMS320F28035: Adding PWM_C to HRPWM example

Part Number:TMS320F28035

I am currently using the example project "Example_2803xHRPWM_Symmetric_Duty_Cycle_SFO_V6" from the "controlSUITE\device_support" folder as a template to implement HRPWM. I would like to add a third PWM output to drive a 3 phase load. I added ePWM3 to the HRPWM_Config() function. However, I haven't been able to synchronize the third output to the first two.

What are the correct register settings, and where should they be placed in the code, to ensure this synchronization occurs properly?

Thank you!
