- ;* Description : STM32F10x High Density Devices vector table for MDK-ARM
- ;* toolchain.
- ;* This module performs:
- ;* - Set the initial SP
- ;* - Set the initial PC == Reset_Handler
- ;* - Set the vector table entries with the exceptions ISR address
- ;* - Configure the clock system and also configure the external
- ;* SRAM mounted on STM3210E-EVAL board to be used as data
- ;* memory (optional, to be enabled by user)
- ;* - Branches to __main in the C library (which eventually
- ;* calls main()).
- ;* After Reset the CortexM3 processor is in Thread mode,
- ;* priority is Privileged, and the Stack is set to Main.

- ; INITIALIZE EXCEPTION VECTORS
- ; 首先对栈和堆的大小进行定义,并在代码区的起始处建立中断向量表,其第一个表项是栈
- ; 顶地址,第二个表项是复位中断服务入口地址。然后在复位中断服务程序中跳转??C/C++标
- ; 准实时库的__main函数。假设STM32被设置为从内部FLASH启动中断向量表起始地位为0x8000000,
- ; 则栈顶地址存放于0x8000000处,而复位中断服务入口地址存放于0x8000004处。当STM32遇
- ; 到复位信号后,则从0x80000004处取出复位中断服务入口地址继而执行复位中断服务程序,
- ; 然后跳转__main函数,最后来到C的世界。
-
- ; DCD指令:作用是开辟一段空间,其意义等价于C语言中的地址符“&”。开始建立的中断向量
- ; 表则类似于使用C语.其每一个成员都是一个函数指针,分别指向各个中断服务函数
-
- ;伪指令AREA,表示开辟一段大小为Stack_Size的内存空间作为栈,段名是STACK,可读可写。
- ;NOINIT:指定此数据段仅仅保留了内存单元,而没有将各初始值写入内存单元,或者将各个内存单元值初始化为0
- ; Amount of memory (in bytes) allocated for Stack
- ; Tailor this value to your application needs
- ; Stack Configuration
- ; Stack Size (in Bytes) <0x0-0xFFFFFFFF:8>
- ;
-
- Stack_Size EQU 0x0000200
-
- AREA STACK, NOINIT, READWRITE, ALIGN=3 ;解释在上面有说明
- Stack_Mem SPACE Stack_Size ;分配连续 Stack_Size 字节的存储单元并初始化为 0。
- __initial_sp ;标号__initial_sp,表示栈空间顶地址。
-
- ; Heap Configuration
- ; Heap Size (in Bytes) <0x0-0xFFFFFFFF:8>
- ;
-
- Heap_Size EQU 0x0000200
-
- AREA HEAP, NOINIT, READWRITE, ALIGN=3 ;ALIGN用来指定对齐方式, 8字节对齐
- __heap_base ;表示堆空间起始地址
- Heap_Mem SPACE Heap_Size
- __heap_limit ;表示堆空间结束地址
-
- PRESERVE8 ;PRESERVE8 指令指定当前文件保持堆栈八字节对齐
- THUMB ;THUMB指令
-
-
- ; Vector Table Mapped to Address 0 at Reset ;实际上是在CODE区(假设STM32从FLASH启动,则此中断向量表起始地址即为0x8000000)
- AREA RESET, DATA, READONLY ;定义一块数据段,只可读,段名字是RESET
- EXPORT __Vectors ;EXPORT:在程序中声明一个全局的标号__Vectors,该标号可在其他的文件中引用
- EXPORT __Vectors_End ;在程序中声明一个全局的标号__Vectors_End
- EXPORT __Vectors_Size ;在程序中声明一个全局的标号__Vectors_Size
