Hi Champ,

I am asking for my customer about the EPWM configuration in PMP41017.

(1). For PWM setup, why the initial CMPA value and CMPB value are given by following in phase 1 sec. side and phase 2 sec. side? How does the minus 11 and 10 come from, why it is needed?

(2). To do the phase shift, it's not seeing any configuration with filling TBPHS value in code. How does the design do for the phase shift? 

(3). Continue #2, why not using TBPHS to give degree phase shift between the two interleaved phases? 

Thanks for the input.

Regards,

Johnny
