M451提供了两路PWM发生器。每路PWM支持6通道PWM输出或输入捕捉。有一个12位的预分频器把时钟源分频后输入给16位的计数器，另外还有一个16位的比较器。PWM计数器支持向上，向下，上下计数方式。PWM用比较器和计数器的比较来产生事件，这些事件用来产生PWM脉冲，中断，EADC/DAC转换触发信号。
PWM发生器支持两种标准PWM输出模式：独立模式和互补模式，它们的架构不同。标准输出模式又有两种输出功能：组功能和同步功能。组功能可以在独立模式和互补模式下使能。同步功能只有在互补模式下才可以被使能。互补模式，有两个比较器产生各种带12位死区时间的PWM脉宽，另外还有一个自由触发比较器来产生给EADC的触发信号。PWM输出控制单元，它支持极性输出，独立管脚屏蔽和刹车功能。
PWM也支持输入捕捉功能，当输入通道有向上跳变、向下跳变、或者两者都有的跳变时，锁存PWM计数器的值到相应的寄存器中。捕捉功能也支持通过PDMA把捕捉到的数据搬移到内存。
捕捉功能特性
支持12个16位解析度的输入捕捉通道
支持上升/下降沿捕捉条件
支持输入上升/下降沿 捕捉中断
支持计数器重载选项的上升/下降沿 捕捉
支持PWM 的所有通道PDMA数据搬移功能
据此可直接观察寄存器
