1、功能说明

    /* 简单描述工程功能 */
        这个例程配置并演示如何修改线程模式特权访问及堆栈


2、使用环境

        软件开发环境：KEIL MDK-ARM V5.34.0.0
                      IAR EWARM 8.50.1
    
        硬件环境：基于评估板N32G430C8L7-STB V1.0开发


3、使用说明

    /* 描述相关模块配置方法；例如:时钟，I/O等 */
        SystemClock：128MHz

        USART：TX - PA9，RX - PA10，波特率115200

    /* 描述Demo的测试步骤和现象 */
        1.编译后下载程序复位运行；
        2.可使用编译器的“Cortex寄存器”窗口查看线程模式下，使用的堆栈及代码的访问级别（特权级/非特权级）；


4、注意事项
    无


1. Function description
    /* A brief description of the engineering function */
    This routine configudes and demonstrates how to modify thread mode privileged access and stack

2. Use environment

    Software development environment: KEIL MDK-ARM V5.34.0.0
                                      IAR EWARM 8.50.1
                                      
    Hardware environment: Developed based on the evaluation board N32G430C8L7-STB V1.0

3. Instructions for use

    /* Describe the related module configuration method; For example: clock, I/O, etc. */
    SystemClock: 128 MHZ
    USART: TX-PA9, RX-PA10, baud rate 115200
    /* Describes the test steps and symptoms of Demo */
    1. Reset and run the downloaded program after compilation;
    2. Use the Compiler's Cortex Register window to view the stack and code access level (privileged/non-privileged) in thread mode.

4. Precautions
    None
