  * @brief     STM32F107xC 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-M3 processor is in Thread mode,
 | 
						|
  *            priority is Privileged, and the Stack is set to Main.
