3 * @file startup_stm32f407xx.s
4 * @author MCD Application Team
5 * @brief STM32F407xx Devices vector table for GCC based toolchains.
6 * This module performs:
7 * - Set the initial SP
8 * - Set the initial PC == Reset_Handler,
9 * - Set the vector table entries with the exceptions ISR address
10 * - Branches to main in the C library (which eventually
11 * calls main()).
12 * After Reset the Cortex-M4 processor is in Thread mode,
13 * priority is Privileged, and the Stack is set to Main.
