3、使用说明
	
	/* 描述相关模块配置方法；例如:时钟，I/O等 */
    系统时钟配置：
        N32H475/N32H482/N32H487:
            SystemClock：240MHz
        N32H474/N32H473:
            SystemClock：240MHz
            
    打印串口配置：
        N32H474/N32H473/N32H482/N32H487:
            USART：TX - PA9，RX - PA10，波特率115200
        N32H475：
            USART：TX - PA9，RX - PA15，波特率115200

	/* 描述Demo的测试步骤和现象 */
        1.分别编译N32H4xx_BOOT0工程和N32H4xx_BOOT1工程并下载；下载完程序后复位运行；
        2.查看串口打印信息，刚上电时从0x8000000启动运行代码；
        3.通过串口下发0x55指令，系统复位并从0x8040000启动运行代码；
        4.通过串口下发0xAA指令，系统复位并从0x8000000启动运行代码。
