+;********************************************************************************
+;* File Name : startup_stm32u083xx.s
+;* Author : MCD Application Team
+;* Description : STM32U083xx Ultra Low Power Devices vector
+;* This module performs:
+;* - Set the initial SP
+;* - Set the initial PC == _iar_program_start,
+;* - 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-M0+ processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.
