TMS320F28035: synchronize 2 phase shift full bridges

Hi,

I wonder how to configure my PWM channels for 2 phase shift full bridges. 

I'm using the  F28035

What I want:

PWM1 and PWM2 is my phase shift full bridge and PWM3 and PWM4 are the synchronous rectifier.

PWM1 -> phase shift -> PWM2

PWM1-> (5 ) -> PWM3

PWM3-> (phase shift - 5) -> PWM4

I looked at the documentation and I don't think  this is possible. Is that correct?

I think I need to change it to this:

PWM1 and PWM3 is my phase shift full bridge and PWM2 and PWM4 are the synchronous rectifier.

PWM1-> 5 -> PWM2 -> phase shift - 5 -> PWM3 ->  -> PWM4

Any better ideas?

Thanks!
