【STM32F334】HRTIM出现异常波形

Zinnia

通过改变HRTIM中Master的MCMP2实现移相出现异常波形：
初始化中配置Master、TimerB和TimerC，均为50%占空比，
TimerB和TimerC各自生成互补波形，TimerB由Master的MCMP1触发复位，TimerC由Master的MCMP2触发复位。
改变Master的MCMP2，使得TimerB和TimerC的波形呈现移相波形。
现在减小MCMP2的值的时候，出现异常波形。
波形如图(通过按键直接改变了两次MCMP2的值，出现了两次异常波形)：


主函数里部分代码：
[mw_shl_code=c,true]for(uint16_t i=0;i<600;i++)
{

}

HRTIM_SetCompare(&hhrtim1,0x500);
for(uint16_t i=0;i<600;i++)
{       
}
HRTIM_SetCompare(&hhrtim1,0x200);
for(uint16_t i=0;i<600;i++)
{       
}[/mw_shl_code]


[mw_shl_code=c,true]void HRTIM_SetCompare(HRTIM_HandleTypeDef * hhrtim, uint16_t Compare1)
{
                hhrtim->Instance->sMasterRegs.MCMP2R = Compare1;

楼主问题解决了吗？有没有keil C的寄存器操作的版本参考下！谢谢！
