bogdanm 0:9b334a45a8ff 6 ;* Description : STM32l053xx Devices vector table for MDK-ARM toolchain.
bogdanm 0:9b334a45a8ff 7 ;* This module performs:
bogdanm 0:9b334a45a8ff 8 ;* - Set the initial SP
bogdanm 0:9b334a45a8ff 9 ;* - Set the initial PC == Reset_Handler
bogdanm 0:9b334a45a8ff 10 ;* - Set the vector table entries with the exceptions ISR address
bogdanm 0:9b334a45a8ff 11 ;* - Branches to __main in the C library (which eventually
bogdanm 0:9b334a45a8ff 12 ;* calls main()).
bogdanm 0:9b334a45a8ff 13 ;* After Reset the Cortex-M0+ processor is in Thread mode,
bogdanm 0:9b334a45a8ff 14 ;* priority is Privileged, and the Stack is set to Main.
