 * @version   V3.2.0
 * @date      03/01/2010
 * @brief     STM32F10x Medium Density Value Line Devices vector table for RIDE7
 *            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.
