Way to set all ePWM registers TBCTR to zero

Hello,

I'm using C28X part of Concerto,

I have the need to change "run time" the period of more ePWM registers and restart sincronously.

I read on datasheet that TBCLKSYNC can stop/start all ePWM in a singol instruction

SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1 or 0;

but I have to write 0 to all EPwmXRegs.TBCTR registers ...

is there a way to set all in a singol instruction or special syncronizing register ??
