说明：  计算机编程手册（CPM）提供程序员理解如何编程给定计算机所需的信息。 本手册主要关注计算机本身，而不是计算机上运行的特定软件。(The Computer Programming Manual (CPM) provides information needed by a programmer to understand how to program a given computer. This manual focuses on the computer itself, not on particular software that will run on the computer.)

说明：  使用定时器TIM3输出四路的SPWM波，其中一二路、三四路波形一致，一二路与三四路波形相差180°(Timer TIM3 is used to output four SPWM waveforms, of which one, two, three and four waveforms are identical, and one, two and three and four waveforms are 180 degrees different.)
