3 * @file startup_stm32f10x_xl.s
4 * @author MCD Application Team
5 * @version V3.5.0
6 * @date 08-April-2011
7 * @brief STM32F10x XL-Density Devices vector table for TrueSTUDIO 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 the clock system and the external SRAM mounted on
13 * STM3210E-EVAL board to be used as data memory (optional,
14 * to be enabled by user)
15 * - Branches to main in the C library (which eventually
16 * calls main()).
17 * After Reset the Cortex-M3 processor is in Thread mode,
18 * priority is Privileged, and the Stack is set to Main.
