你好，请问怎样设置才能使正在工作的某个PWM停下来？谢谢
楼主参考以下：
初始化配置：
EALLOW;
EPwm1Regs.TZSEL.bit.OSHT1 = 1; //enable TZ1 for OSHT
EPwm2Regs.TZSEL.bit.OSHT1 = 1; //enable TZ1 for OSHT
EPwm3Regs.TZSEL.bit.OSHT1 = 1; //enable TZ1 for OSHT
// What do we want the OST/CBC events to do?
// TZA events can force EPWMxA
// TZB events can force EPWMxB
EPwm1Regs.TZCTL.bit.TZA = TZ_FORCE_LO; // EPWMxA will go low 根据需要设置停止输出时的PWM电平。
EPwm1Regs.TZCTL.bit.TZB = TZ_FORCE_LO; // EPWMxB will go low
EPwm2Regs.TZCTL.bit.TZA = TZ_FORCE_LO; // EPWMxA will go low
EPwm2Regs.TZCTL.bit.TZB = TZ_FORCE_LO; // EPWMxB will go low
EPwm3Regs.TZCTL.bit.TZA = TZ_FORCE_LO; // EPWMxA will go low
EPwm3Regs.TZCTL.bit.TZB = TZ_FORCE_LO; // EPWMxB will go low
EDIS;
以下为停止PWM输出：
// Stop PWM output
//===========================================================================
//Force trip EPwm1,2,3
EPwm1Regs.TZFRC.bit.OST = 0x1; //disabPWMl
EPwm2Regs.TZFRC.bit.OST = 0x1; //disabPWM2
EPwm3Regs.TZFRC.bit.OST = 0x1; //disabPWM3
以下为使能PWM输出：
// Enable PWM output
//EnablePWM EPwm1,2,3
EPwm1Regs.TZCLR.bit.OST = 1; //EnablePWM1
EPwm2Regs.TZCLR.bit.OST = 1; //EnablePWM2
EPwm3Regs.TZCLR.bit.OST = 1; //EnablePWM3
请问这个地方
是否是应该改成OSHT2 OSHT3。如果你这样设置道理是什么样子的？是否是只用1个OSHT1就可以完成6路pwm的封锁呢？
OSHT1为1代表允许TZ1 为OSHT保护模式，任何一个TZ信号都可以配置为保护一个或者多个PWM模块的PWM输出。因此下面的配置，可以实现6路PWM的封锁。
那么TZ信号触发之后是否立即实现6路PWM的封锁，如果使能TZ中断，则TZ的中断优先级对PWM的封锁有没有影响？
