两路pwm输出移相，但是我配置了还是两路一模一样

我这样配置
EPwm1Regs.TBCTL.bit.PHSEN = TB_ENABLE;
EPwm1Regs.TBPHS.half.TBPHS = 0;
EPwm2Regs.TBCTL.bit.PHSEN = TB_ENABLE ;
EPwm2Regs.TBPHS.half.TBPHS =100;
下面是我的初始化：
main里面：
EALLOW;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0;
EDIS;
InitEPwm1Example();
InitEPwm2Example();
EALLOW;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1;
EDIS;
void InitEPwm1Example()
[
EPwm1Regs.TBPRD = 600;

EPwm1Regs.TBCTR = 0x0000;
EPwm1Regs.CMPA.half.CMPA = 300;
EPwm1Regs.CMPB = 300;
EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
EPwm1Regs.TBCTL.bit.PHSEN = TB_ENABLE ;
EPwm1Regs.TBPHS.half.TBPHS = 0;
EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1;
EPwm1Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.LOADAMODE = CC_CTR_ZERO_PRD;
EPwm1Regs.CMPCTL.bit.LOADBMODE = CC_CTR_ZERO_PRD;
EPwm1Regs.AQCTLA.bit.CAU = AQ_CLEAR;
EPwm1Regs.AQCTLA.bit.CAD = AQ_SET;
EPwm1Regs.AQCTLB.bit.CAU = AQ_SET;
EPwm1Regs.AQCTLB.bit.CAD = AQ_CLEAR;
EPwm1Regs.ETSEL.bit.INTSEL = ET_CTR_ZERO;
EPwm1Regs.ETSEL.bit.INTEN = 1;
EPwm1Regs.ETPS.bit.INTPRD = ET_1ST;
