LAUNCHXL-F28379D: wrong Phase shift at ePWM1, and hence wrong phase-shift at consecutive blocks ePWM2, ePWM3, ePWM4 etc...

Hi, 

I would like to have a phase shift of X (say 90) degrees, at the first ePWM1 block. 

With respect to ePWM1, I would like to configure other ePWM blocks(ePWM2, ePWM3, etc...).

My model works till there is 0 phase shift at the ePWM1, the moment I try some phase shift at ePWM1..the whole configuration collapses. 

I get wrong duty cycle, wrong phaseshift with other blocks,..etc..
