  * @brief     STM32F105xC Devices vector table for Atollic toolchain.
8
  *            This module performs:
9
  *                - Set the initial SP
10
  *                - Set the initial PC == Reset_Handler,
11
  *                - Set the vector table entries with the exceptions ISR address
12
  *                - Configure the clock system   
13
  *                - Branches to main in the C library (which eventually
14
  *                  calls main()).
15
  *            After Reset the Cortex-M3 processor is in Thread mode,
16
  *            priority is Privileged, and the Stack is set to Main.
