;*******************************************************************************
;* File Name : startup_stm32f401xe.s
;* Author : MCD Application Team
;* Description : STM32F401xe devices vector table for MDK-ARM 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 CortexM4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

* (*) HSI_VALUE is a constant defined in stm32f4xx_hal_conf.h file (default value
* 16 MHz) but the real value may vary depending on the variations
* in voltage and temperature.

* (**) HSE_VALUE is a constant defined in stm32f4xx_hal_conf.h file (its value
