1、功能说明
    此例程展示了CM4内核下的IWDG复位功能。

2、使用环境

    软件开发环境：KEIL MDK-ARM V5.34
    		     IAR EWARM 8.50.1
         
    芯片支持：  
        N32H785
        N32H785xxxEC
        N32H787

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  M4核 300MHz

      3、指示灯：PA1(LED1)   PA2(LED2)  

    测试步骤及现象：

        1、编译后将CM7和CM4的工程程序分别下载到开发板并复位运行
		2、指示灯LED2不停的闪烁。说明窗口值刷新正常，代码正常运行。
        3、把SysTick_Delay_Ms( )函数参数改成250以上，整个系统将一直处于复位状态，LED1亮。

1. Function description

    IWDG reset function.
    

2. Development environment

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

    Supported chips:
        N32H785
        N32H785xxxEC
        N32H787		  

3. How to use

    System Configuration:
        1. Clock source: HSI+PLL
        2. System Clock frequency: 
             M7 Core：600MHz  M4 Core：300MHz

     3、PA1(LED1)   PA2(LED2)  

    Test steps and phenomenon：
	   1. After compiling, download the program of CM7 and CM4 projects respectively and reset, the program start running
       2. The indicator LED2 keeps flashing,It means that the window value is refreshed normally and the code is running normally
       3. Change the SysTick_Delay_Ms() function parameter to above 250. the entire system will always be in the reset state. LED1 is on.
