TMS320F280049C的epwm模块是否支持Burst mode?

即通过确定epwm的on周期,off周期决定epwm的输出或不输出,类似下图STM32的相关示意图。之前看280049的指南没有相关功能描述,若280049没有burst mode  是否有相关功能替代???

  • 控制使能或关闭的寄存器结合TZ 应该能满足你的需求
  • 同意楼上的看法,您可以尝试以下代码

    //Disable the PWM 
    
    
    EALLOW;
    EpwmxRegs.TZFRC.bit.OST = 1;
    EpwmxRegs.TZCTL.bit.TZA = 0x02; // fOR FORCE low 
    EpwmxRegs.TZCTL.bit.TZB = 0x02; //fOR fORCE loW
    EDIS;
    
    
    //Enable the PWM
    
    
    EALLOW;
    EpwmxRegs.TZCTL.bit.OST = 0x01; // fOR FORCE low 
    EpwmxRegs.TZCTL.bit.OST = 0x01; //fOR fORCE loW
    EDIS;
