6 ;* Description : STM32l053xx Devices vector table for MDK-ARM toolchain.
7 ;* This module performs:
8 ;* - Set the initial SP
9 ;* - Set the initial PC == Reset_Handler
10 ;* - Set the vector table entries with the exceptions ISR address
11 ;* - Branches to __main in the C library (which eventually
13 ;* After Reset the Cortex-M0+ processor is in Thread mode,
14 ;* priority is Privileged, and the Stack is set to Main.
