   * @brief     STM32F101xG 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.
