大佬们，我配置了TZ中断，外部TZ1由高变低进不去中断，使用软件触发也进不去，配置如下：
//错误联防TZ
EPwm1Regs.TZSEL.bit.OSHT1=1;//使能TZ1（低）联防、
EPwm1Regs.TZCTL.bit.TZB=2;//联防使PWM为低
EPwm1Regs.TZCTL.bit.TZA=2;
EPwm1Regs.TZCLR.bit.INT = 1;
EPwm1Regs.TZCLR.bit.INT = 1;
EPwm1Regs.TZEINT.bit.OST=1;//使能中断
EALLOW;
PieVectTable.EPWM1_TZINT=&PWM1_TZ;//TZ
EDIS;
PieCtrlRegs.PIEIER2.bit.INTx1=1;//TZ
IER |=M_INT2;//TZ
EINT;
//中断服务程序
TZ=1;
PieCtrlRegs.PIEACK.all=PIEACK_GROUP2;
EPwm1Regs.TZCLR.bit.OST=1;
EPwm1Regs.TZCLR.bit.INT=1;
在主程序使用EPwm1Regs.TZFRC.bit.OST=1;触发不了TZ中断，变量TZ一直都是0
