******************************************************************************
* @file startup_stm32.S
* @file startup_stm32l496xx.s
* @author MCD Application Team
* @version V2.0.0
* @date 18-February-2014
* @brief STM32Fxxxxx Devices vector table for Atollic TrueSTUDIO toolchain.
* @brief STM32L496xx devices vector table GCC toolchain.
* This module performs:
* - Set the initial SP
* - Set the initial PC == Reset_Handler,
* - Set the vector table entries with the exceptions ISR address
* - 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/M7 processor is in Thread mode,
* After Reset the Cortex-M4 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.
* Taken from STM32L4 template code for stm32l496 in STM32Cube_FW_L4_V1.11.0
