+  * @file      startup_stm32f401xe.s
+  * @author    MCD Application Team
+  * @version   V2.0.0
+  * @date      18-February-2014 
+  * @brief     STM32F401xExx Devices vector table for Atollic TrueSTUDIO 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-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.
