+;* File Name : startup_stm32f401xe.s
+;* Author : MCD Application Team
+;* Description : STM32F401xExx devices vector table for EWARM toolchain.
+;* This module performs:
+;* - Set the initial SP
+;* - Set the initial PC == _iar_program_start,
+;* - Set the vector table entries with the exceptions ISR
+;* address.
+;* - Configure the system clock
+;* - 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.
