+;* File Name : startup_stm32l431xx.s
+;* Author : MCD Application Team
+;* Description : STM32L431xx Ultra Low Power 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 Cortex-M4 processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.
+;* <<< Use Configuration Wizard in Context Menu >>>
