/**************************************************************************//**
STM32的内核是ARM CORTEX-M3，这个core_cm3.h包含的是一些内核相关的函数和宏定义，例如核内寄存器定义、部分核内外设的地址等等，其对应的是core_cm3.c文件。
* @file    core_cm3.h
* @brief CMSIS Cortex-M3 Core Peripheral Access Layer Header File 外设接口进入头文件
微控制器软件接口标准(CMSIS：Cortex Microcontroller Software Interface Standard) 是 Cortex-M 处理器系列的与供应商无关的硬件抽象层。
使用CMSIS，可以为处理器和外设实现一致且简单的软件接口，从而简化软件的重用、缩短微控制器新开发人员的学习过程，并缩短新设备的上市时间。

#ifndef __CM3_CORE_H__
条件编译语句，语句1 #ifndef 标识1
语句2 #define 标识1
语句3 #endif
语句4 ……
语句5 ……
该段代码意思是：如果标识1没有被定义，则重定义标识1，即执行语句2、语句3;如果标识1已经被定义，则直接跳过语句2、语句3，直接执行语句4、语句5、……
/***********************************/
备注：#ifndef 和 #endif 要一起使用，如果丢失#endif，可能会报错。
千万不要忽略了头文件中的#ifndef，这是一个很关键的东西。比如你有两个C文件，这两个C文件都include了同一个头文件。而编译时，这两个C文件要一同编译成一个可运行文件，于是问题来了，大量的声明冲突。
例如要编写头文件test.h
在头文件开头写上两行：
#ifndef _TEST_H
#define _TEST_H//一般是文件名的大写头文件结尾写上一行：
#endif
这样一个工程文件里同时包含两个test.h时，就不会出现重定义的错误了。
