如题，想通过输入类型的GPIO88，然后经过InputXbar然后到EpwmXbar然后通过Trip4到ePwmModules,发现怎么都触发不了：
CPU1配置Xbar:
EALLOW;
InputXbarRegs.INPUT12SELECT = 88;
EPwmXbarRegs.TRIP4MUXENABLE.BIT.MUX27 = 1;
EPwmXbarRegs.TRIP4MUX16TO31CFG.BIT.MUX27 = 1;
EPwmXbarRegs.TRIPOUTINV.BIT.TRIP4 = 1;
EDIS;
cpu2配置触发信号:
EALLOW;
EPwm1Regs.TZSEL.BIT.DCAEVTA =1;
EPwm1Regs.DCTRIPSEL.BIT.DCALCOMPSEL = 4;
EPwm1Regs.TZDCSEL.BIT.DCAEVT1 = 3;//GPIO低电平触发
EPwm1Regs.DCACTL.BIT.EVT1SRCSEL = 0;
EPwm1Regs.DCACTL.BIT.EVT1FRCSYNCSEL = 1;
EPwm1Regs.DCACTL.BIT.EVT1LATSEL = 0;
EPwm1Regs.TZCTL.BIT.DCAEVT1 = 1;
EPwm1Regs.TZCTL2.BIT.ETZE= 0;
EPwm1Regs.TZCTL.BIT.TZA = 1;
EPwm1Regs.TZCTL.BIT.TZB = 1;
EDIS;
gpio88已经配置好上拉，在仿真上可以看到信号正常翻转了，但是在EPwm1Regs.TZOSTFLG.BIT.DCAEVT1一直是0，也就是说没有触发到事件。我想问一下我上面的配置有问题吗？我用TZ3直接触发OST1是没有问题的，现在用上epwmXbar做转接不知道那出错了，也没能找到相关例程，希望大神门指教一下
