1、功能说明
    1、systick 100ms触发TIM1输出6步换相波形
2、使用环境
    软件开发环境：KEIL MDK-ARM V5.34.0.0
    硬件开发环境： 
        N32G05x系列：
            基于评估板N32G05xRBQ7_STB V1.0开发
        N32G05x系列：
            基于评估板N32G05xRBL7_STB V1.0开发
3、使用说明
    系统配置:
        1、时钟源：
                    HSI=8M,SYS CLK=64M,TIM1 CLK=64M
        2、中断：
                    TIM1 COM事件中断打开，优先级1
                    Systick 100ms中断，优先级0
        3、端口配置：
                    PA4选择为TIM1 CH1输出
                    PA6选择为TIM1 CH2输出
                    PA11选择为TIM1 CH3输出
                    PA5选择为TIM1 CH1N输出
                    PB14选择为TIM1 CH2N输出
                    PB15选择为TIM1 CH3N输出
        4、TIM：
                    TIM1 6路互补冻结输出模式，无刹车，开COM中断
    使用方法：
        1、编译后打开调试模式，用示波器或者逻辑分析仪观察TIM1的输出波形
        2、每隔100ms systick触发COM中断，在TIM的COM中断里面输出AB AC BC BA CA CB的6步换相波形

1. Function description
    1. systick triggers TIM1 for 100ms to output 6-step commutation waveform
2. Use environment
	Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware development environment:
         N32G05x series:
            Developed based on the evaluation board N32G05xRBQ7_STB V1.0
         N32G05x series:
            Developed based on the evaluation board N32G05xRBL7_STB V1.0
3. Instructions for use
    System Configuration;
        1. Clock source:
                    HSI=8M,SYS CLK=64M,TIM1 CLK=64M
        2. Interrupt:
                    TIM1 COM event interrupt on, priority 1
                    Systick 100ms interrupt, priority 0
        3. Port configuration:
                    PA4 is selected as TIM1 CH1 output
                    PA6 is selected as TIM1 CH2 output
                    PA11 is selected as TIM1 CH3 output
                    PA5 is selected as TIM1 CH1N output
                    PB14 is selected as TIM1 CH2N output
                    PB15 is selected as TIM1 CH3N output
        4. TIM:
                    TIM1 6-channel complementary freeze output mode, no brake, open COM interrupt
    Instructions:
        1. Open the debug mode after compiling, and observe the output waveform of TIM1 with an oscilloscope or logic analyzer
        2. The systick triggers the COM interrupt every 100ms, and outputs the 6-step commutation waveform of AB AC BC BA CA CB in the COM interrupt of the TIM
4. Matters needing attention
