1、功能说明
    1、STANDBY模式的进入和退出。

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：
          N32H760 系列
          N32H762 系列
          N32H765 系列
          N32H765EC 系列
          
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
    3、唤醒源：
        WAKEUP按键-PA0
    4、打印：PA9 - baud rate 115200

    使用方法：
        在KEIL下编译后烧录到评估板，串接电流表，上电后一段时间进入STANDBY模式，电流明显变小。按下WAKEUP按键，退出STANDBY模式，电流变大。
        如果开启打印输出，可以看到串口输出“Entry STANDBY mode”，唤醒后输出“--- Reset ---”，说明STANDBY唤醒后从0地址开始执行。

4、注意事项
    在评估功耗的时候，要注意去掉打印

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34
                                      IAR EWARM 8.50.1 
    Supported chips:
          N32H760 series
          N32H762 series
          N32H765 series
          N32H765EC series
          
3. How to use

    System Configuration:
    1. Clock source: HSI+PLL
    2. System Clock frequency:
       M7 core :  600MHz

    3. Wake-up source: 
        WAKEUP button-PA0
    4. printf: PA9 - baud rate 115200

     Instructions:
        Compiled under KEIL and burned to the evaluation board, connected an ammeter in series, powered up and went into STANDBY mode for a while and the current became significantly lower. Press the WAKEUP button to exit STANDBY mode, and the current is back.
        If you turn on the printout, you can see that the serial port outputs "Enter STANDBY mode" and "---- Reset ----" after waking up, which means that STANDBY wakes up and starts executing from address 0..

4. Attention
    When evaluating power consumption, pay attention to removing the printf
