1、功能说明
    1、SLEEP模式的进入和退出。


2、使用环境

    软件开发环境：KEIL MDK-ARM V5.25

    硬件环境：
        1、基于评估板N32G43XRL-STB V1.0开发
        2、MCU：N32G435RBL7


3、使用说明
    
    系统配置；
        1、时钟源：HSE+PLL
        2、时钟频率：108MHz
        3、唤醒源：PA0
        4、串口配置：
            - 串口为USART1（TX：PA9  RX：PA10）:
            - 数据位：8
            - 停止位：1
            - 奇偶校验：无
            - 波特率： 115200 

    使用方法：
        在KEIL下编译后烧录到评估板，串接电流表后，上电后过以一会，电流明显变小。按下唤醒按键PA0,LED1闪烁，
        电流又明显变大,过一会又变小。


4、注意事项
    无



1. Function description
    1. Enter and exit the SLEEP mode.

2. Use environment
    Software development environment: KEIL MDK-ARM V5.25
    Hardware environment:
	1. based on the evaluation board N32G43XRL-STB V1.0 development
	2. MCU: N32G435RBL7

3. Instructions for use    
    System configuration;
	1. Clock source: HSE+PLL
	2. Clock frequency: 108MHz
	3. Wake up source: PA0
	4. Serial port configuration:
	    - Serial port: USART1 (TX: PA9 RX: PA10) :
	    - Data bit: 8
	    - Stop bit: 1
	    - Parity check: None
	    - Baud rate: 115200
    Instructions:
	After compiling under KEIL, it was burned to the evaluation board, connected to the ammeter in series, and after powering on for a while, the current decreased significantly. Press the wake up button PA0,LED1 flashes,
	The current increases significantly, and then decreases again.

4. Attention
    None
