;* 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>>>
