How to insert deatime in PWM by eTPU of MPC5554

Hello,

I am looking for document which explains how to insert deadtime of PWM by eTPU of MPC5554. I did read some documents, like "PMSM Vector Control, Driven by eTPU on MPC5500",but all these documents use MC33937 to generate deadtime. So I want to ask how can I generate deadtime for PWM by setting  up eTPU without using any pre-driver to generate deadtime? Is there any demo for me to study? Thank you very much!

Emily

Dead time is a parameter of PWMMAC function. It is generated by eTPU module.

Pay attention to AN2969 - Using the AC Motor Control PWM eTPU Functions
