epwm modules synchronization and phase shift

Hi, I want to synchronize the epwm 1-2, epwm 3-4, and epwm 5-6 modules with each other and apply a phase shift in the f28335 DSP. How can I achieve this?

The link provided below shows an example, but it is not specific to f28335, and the mentioned settings are not available. I hope you can assist me in this matter.
