1、功能说明
    1、PVD配置电压产生对应的中断。

2、使用环境

    软件开发环境：KEIL MDK-ARM Professional Version 5.34

    硬件环境：最小系统板N32G003F5S7-STB_V1.0 

3、使用说明

    系统配置；
        - 系统时钟 = 48MHz

    使用方法：
        在KEIL下编译后烧录到评估板，通过仿真器进入调试模式，在PVD_IRQHandler()中设置断点。
        全速运行。然后再把电压调到PVD设置电压附近，此时程序会停在断点处。

4、注意事项
    无


1. Function description
    1. The PVD configuration voltage generates a corresponding interrupt.


2. Use environment

    Software development environment: KEIL MDK-ARM Professional Version 5.34

    Hardware environment: minimum system board N32G003F5S7-STB_V1.0


3. Instructions for use

    System Configuration;
        -System clock = 48MHz

    Instructions:
        After compiling under KEIL, burn it to the evaluation board, enter the debug mode through the emulator, and set a breakpoint in PVD_IRQHandler().
        Running at full speed. Then adjust the voltage to the vicinity of the PVD setting voltage, and the program will stop at the breakpoint at this time.


4. Matters needing attention
    none
