我想得到一个EPWM1A、EPWM1B之间相差一个占空比相位的波形，为什么我初始化完成之后连波形都没有了，希望各位帮我找一下问题
初始化程序如下
void InitEPwm1Example()
{
EPwm1Regs.CMPA.half.CMPA = 2500;
EPwm1Regs.CMPB = 5000;
EPwm1Regs.TBPRD = 10000;
EPwm1Regs.TBPHS.half.TBPHS = 0x0000; // Phase is 0
EPwm1Regs.TBCTR = 0x0000; // Clear counter
// Setup counter mode
//EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN; // Count up
EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UP;
EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1; // Clock ratio to SYSCLKOUT
EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1;//0x0-1分频,TBCLK = SYSCLKOUT / (HSPCLKDIV × CLKDIV)
EPwm1Regs.TBCTL.bit.PHSEN = TB_DISABLE; // Master module
EPwm1Regs.TBCTL.bit.PRDLD = TB_SHADOW;
EPwm1Regs.TBCTL.bit.SYNCOSEL = TB_CTR_ZERO; // Sync down-stream module
// Setup shadowing
EPwm1Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.LOADAMODE = CC_CTR_zero; // Load on Zero时间基准计数器等于周期
EPwm1Regs.CMPCTL.bit.LOADBMODE = CC_CTR_zero;
// Action Qualifier SubModule Registers
EPwm1Regs.AQCTLA.bit.ZRO = AQ_SET;//AQ_CLEAR;
EPwm1Regs.AQCTLA.bit.CAD = AQ_CLEAR;//AQ_SET达到CMPA的值变为低电平;
EPwm1Regs.AQCTLB.bit.CAU = AQ_SET;//达到CMPB的值变为低电平
EPwm1Regs.AQCTLB.bit.CBD = AQ_CLEAR;
//EPwm1Regs.AQCTLB.bit.PRD = AQ_CLEAR;
}
void InitEPwm2Example()
{
EPwm2Regs.CMPA.half.CMPA = 2500;
EPwm2Regs.CMPB = 5000;
EPwm2Regs.TBPRD = 10000;
// Setup TBCLK
EPwm2Regs.TBPHS.half.TBPHS = 0x0000; // Phase is 0
EPwm2Regs.TBCTR = 0x0000; // Clear counter
// Setup counter mode
EPwm2Regs.TBCTL.bit.CTRMODE = TB_COUNT_UP; // Count up

EPwm2Regs.TBCTL.bit.CLKDIV = TB_DIV1;//0x0-1分频,TBCLK = SYSCLKOUT / (HSPCLKDIV × CLKDIV)
EPwm2Regs.TBCTL.bit.PHSEN = TB_ENABLE; // Slave module
EPwm2Regs.TBCTL.bit.PRDLD = TB_SHADOW;
EPwm2Regs.TBCTL.bit.SYNCOSEL = TB_SYNC_IN;//TB_SYNC_DISABLE; // sync flow-through
// Setup shadowing
EPwm2Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm2Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm2Regs.CMPCTL.bit.LOADAMODE = CC_CTR_zero; // Load on Zero
EPwm2Regs.CMPCTL.bit.LOADBMODE = CC_CTR_zero;
// Action Qualifier SubModule Registers
EPwm2Regs.AQCTLA.bit.ZRO = AQ_SET;//AQ_CLEAR;
