;* File Name : stm32f10x_vector.s
;* Author : MCD Application Team
;* Version : V1.1.2
;* Date : 09/22/2008
;* Description : STM32F10x vector table for RVMDK 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 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.
;* <<< Use Configuration Wizard in Context Menu >>>
