 * @brief     STM32F10x Medium Density 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
 *                - 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.
