-  * @date      31-March-2017

-  * @brief     STM32F103xB 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.
