EPwm1Regs.TBPRD = MPeriod; \
EPwm2Regs.TBPRD = MPeriod; \
EPwm3Regs.TBPRD = MPeriod;

The cycle should be fixed.Is that so?Why is it changing now.

The final TBPRD is equal to PeriodMax or PeriodMax-1, and keep no change as set PeriodMax to TBPRD directly. This macro function is enable to change MfuncPeriod for variable pwm period to support synchronous mode.

The duty ratio of PWM is changed, but the basic period is fixed, isn't it?
