4 * @author MCD Application Team
5 * @version V3.1.2
6 * @date 09/28/2009
7 * @brief STM32F10x High Density Devices vector table for RIDE7 toolchain.
8 * This module performs:
9 * - Set the initial SP
10 * - Set the initial PC == Reset_Handler,
11 * - Set the vector table entries with the exceptions ISR address,
12 * - Configure external SRAM mounted on STM3210E-EVAL board
13 * to be used as data memory (optional, to be enabled by user)
14 * - Branches to main in the C library (which eventually
15 * calls main()).
16 * After Reset the Cortex-M3 processor is in Thread mode,
17 * priority is Privileged, and the Stack is set to Main.
