说说M451例程之PWM的寄存器讲解

[db:关键字] 作者: 来源: 发布时间:2019-05-22 23:33:10   浏览:24

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
