1. Function description
    1. IWDG reset function.
	
2. Use environment
    Software development environment: KEIL MDK-ARM V5.25.0.0
	
    Hardware environment: 
		1.Developed based on the evaluation board N32L43XML-STB V1.0
		2.MCUN32L436MBL7
	
3. Instructions for use
    System Configuration;
        1. IWDG clock source: LSI/32

		2. Timeout value: 250ms

		3. Indicator light: LED1(PA8) LED3(PB5)

    Instructions:
        1. After compiling in KEIL, it was burned to the evaluation board. After powering on,the indicator controled by PB5 pin kept flashing. The IWDG feeds the dog properly and the code runs properly.
		2. When the parameter of Delay(249) function is changed to more than 250, the entire system will always be reset. LED1,LED3 are always on.
		
4. Matters needing attention
    If you simulate through the burner, you need to turn on DBG_ ConfigPeriph(DBG_IWDG_STOP,ENABLE).
