     我想知道上面五个配置情况下，六路比较输出通道输的的PWM以及相应引脚的电平状态，谢谢

1.TIM_SelectOCxM():    Selects the TIM Output Compare Mode   选择定时器的输出比较模式
2.TIM_CCxCmd（）：使能或者失能定时器的捕获比较通道   列出来的函数在库中都有注释的，去翻译和理解函数@！

能不能请您花一点时间帮我翻译出来，我现在急切的希望知道意思好去做后面的事情，多谢

谁能告诉我，上面这两个设置输出的电平是否相同？

第一种，输出比较主动模式，只有通道1的反向通道工作，匹配时设置输出引脚为有效电平，当计数值为比较/捕获寄存器值相同时，强制输出为高电平)  。第二种，输出比较非主动模式 ，只有通道1工作，(匹配时设置输出引脚为无效电平，当计数值为比较/捕获寄存器值相同时，强制输出为低电平)

第一种通道1输出高还是低？
