样例使用说明
Sample Description
================================================================================
功能描述：
此样例是对高级定时器功能“六步PWM的产生”的演示，通过systick中断作为COM commutation
事件的触发源，实现（无刷电机的）换向,下表是换向步骤，比如第一步中的CH1和CH3N为1，
即设置打开这两个通道的PWM输出。
Function descriptions:
This sample demonstrates advanced timer function 'six-step PWM generation',
systick interrupt as COM commutation event trigger source to achieve commutation
(brushless motor).
The following table shows the commutating steps. For example, CH1 and CH3N in
the first step are set to 1, that mean the PWM output of these two channels is
set to start
