;* Description : STM32l071xx 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-M0+ processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.
