3、使用说明
    系统配置；
        1、时钟源：HSI+PLL
        2、系统时钟频率：
            M7核: 600MHz
        3、中断：
			GTIMA1 比较中断打开
        4、端口配置：
			PA1选择为IO 输出
			PA2选择为IO 输出
			PA3选择为IO 输出
			PA4选择为IO 输出
        5、TIM：
			GTIMA1 配置好CH1 CH2 CH3 CH4的比较值，并打开比较中断
    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PA1 PA2 PA3 PA4的波形
        2、定时器运进入CC1 CC2 CC3 CC4中断后,对应拉低PA1 PA2 PA3 PA4的IO

4、注意事项
    无
    
1. Function description
    1. After GTIMA1 CH1 CH2 CH3 CH4 reaches the CC value, correspondingly pull down the IO level of PA1, PA2, PA3, and PA4

2. Development environment
    Software development environment: KEIL MDK-ARM V5.34
    Software development environment: IAR EWARM 8.50.1

    Supported chips:
        N32H730  
        N32H735   
        N32H735EC
        N32H760
        N32H762
        N32H765
        N32H765EC
        N32H785
        N32H785EC
        N32H787

3. How to use
   System Configuration:
        1. Clock source: HSI+PLL
        2. System Clock frequency: 
            M7 Core:     600MHz
        3. Interruption:
			GTIMA1 compare interrupt is turned on
        4. Port configuration:
			PA1 is selected as IO output
			PA2 is selected as IO output
			PA3 is selected as IO output
			PA4 is selected as IO output
        5. TIM:
			GTIMA1 configures the comparison value of CH1, CH2, CH3, CH4, and turns on the comparison interrupt
    Instructions:
        1. After compiling, turn on the debug mode, and use an oscilloscope or logic analyzer to observe the waveforms of PA1, PA2, PA3, and PA4
        2. After the timer enters the CC1 CC2 CC3 CC4 interrupt, it will correspondingly pull down the IO of PA1 PA2 PA3 PA4
4. Attention
    None
