* Description        : STM32F10x 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 external SRAM mounted on STM3210E-EVAL board
*                       to be used as data memory (optional, to be enabled by user)
*                      - 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.
