1. Function description

    IWDG reset function.
    

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. IWDG clock source: LSI/128
       2. Timeout value: 250ms
       3. light Indicator: LED1(PB0) LED2(PC12)

    Test steps and phenomenon
       1. Compile and download the code to reset and run.The indicator LED2 
          keeps flashing. It means that IWDG feeds the dog normally and the code runs normally.
       2. Change the parameter of the SysTick_Delay_Ms() function from 249 to 251 or more, the whole system
          will always be in the reset state, and LED1 will be on.
