  * @author    MCD Application Team 
  * @version   V1.0.1 
  * @date      20-April-2012 
  * @brief     STM32F0xx 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 
  *                - Branches to main in the C library (which eventually 
  *                  calls main()). 
  *            After Reset the Cortex-M0 processor is in Thread mode, 
  *            priority is Privileged, and the Stack is set to Main.
