;* File Name          : startup_stm32f10x_hd.s

;* Author             : MCD Application Team

;* Version            : V3.4.0

;* Date               : 10/15/2010

;* 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.

描述:STM 32 f 10 x MDK ARM高密度器件向量表；*工具链。；*此模块执行:；* -设置初始SP；* -设置初始PC = = Reset _ Handler* -用异常ISR地址设置向量表项；* -配置时钟系统并配置外部；*安装在STM3210E-EVAL板上的SRAM用作数据；*内存(可选，由用户启用)；* -分支到C库中的__main(最终；*调用main())。；*复位后CortexM3处理器处于线程模式；*优先级是有特权的，堆栈设置为Main。；* < < <在上下文菜单中使用配置向导>>>
