* @version V4.2.0
* @date 31-March-2017
* @brief STM32F103xE Devices vector table for Atollic 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
* - 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 Cortex-M3 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.
