  * @version   V1.1.3 
  * @date      05-March-2012 
  * @brief     STM32F2xx Devices vector table for RIDE7 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 system clock and the external SRAM mounted on  
  *                  STM322xG-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.
