synchronising 2 dsps through epwmsynci

I need to synchronise two DSos -28335.  i want the carrier signals (counter) of the two DSPs  to be out of phase. At the zero of carrier in DSP-1, a signal is sent to DSP-2 for trigerring epwmsynci and its counter will load TBPHS=PWM PERIOD of the DSP-2. But I always find that the carriers are in phase. The value on TBPHS seems to have no effect on the carriers, they always remain in phase

Can you suggest any probable mistake I am doing?
