1、功能说明
    1、PD模式的进入和唤醒退出。


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N32G030C8L7-STB V1.0开发
	2、MCU：N32G030C8L7

3、使用说明

    系统配置；
        1、时钟源：HSE+PLL
        2、时钟频率：48M

    使用方法：
        在KEIL下编译后烧录到评估板，串接电流表，上电后过一会，电流明显变小。按下WAKEUP按键，电流回到了mA级别。过了一会又降到uA。
        如果开启打印输出，可以看到串口输出“Lower Power Entry”，唤醒后输出“PWR_PD INTI”，说明PD唤醒后从0地址开始执行。
            

4、注意事项
    无


1. Function description
    1. Entry and wake-up exit of PD mode.


2. Use environment

    Software development environment: 
        IDE tool: KEIL MDK-ARM V5.25
      
    Hardware environment: 
        Development board: N32G030C8L7-STB V1.0
	MCU：N32G030C8L7

3. Instructions for use

    System Configuration;
        1. Clock source: HSE+PLL
        2. Clock frequency: 48M

    Instructions:
        After compiling under KEIL, it is burned to the evaluation board, and the ammeter is connected in series. After a while, the current becomes significantly smaller. Press the WAKEUP button and the current returns to mA level. After a while it drops to uA again.
        If you turn on the print output, you can see that the serial port outputs "Lower Power Entry", and after waking up, it outputs "PWR_PD INTI", indicating that the PD starts to execute from address 0 after waking up.
