SMT32高精度定时器HRTIM，要配成一路：180的推挽PWM,分别是占空比0-48%，通道A上下互补通道B上下互补共四个脚输出，运行中切换成，配成另一路180的推挽PWM,分别是占空比50-98%，通道A上下互补通道，B通道关闭。现在是能分别配出，但是在切换过中就不对，。是哪里不对，求各位指点。

占空比50-98%通道A上下互补通道，B通道关闭，二个脚输出

以下是占空比0-48%通道A上下互补通道B上下互补共四个脚输出，

从你给出的信息来看，好像在说，使用TIMA和 TIMB各输出一对互补pwm信号。


希望中途调整TIMA的PWM输出的占空比，同时关闭TIMB的输出。是这个意思吗？


另外，你目前基于什么时机或事件来做调整切换？
