mbed_official 376:cb4d9db17537 6 ;* Description : STM32l053xx Devices vector table for MDK-ARM toolchain.
mbed_official 376:cb4d9db17537 7 ;* This module performs:
mbed_official 376:cb4d9db17537 8 ;* - Set the initial SP
mbed_official 376:cb4d9db17537 9 ;* - Set the initial PC == Reset_Handler
mbed_official 376:cb4d9db17537 10 ;* - Set the vector table entries with the exceptions ISR address
mbed_official 376:cb4d9db17537 11 ;* - Branches to __main in the C library (which eventually
mbed_official 376:cb4d9db17537 12 ;* calls main()).
mbed_official 376:cb4d9db17537 13 ;* After Reset the Cortex-M0+ processor is in Thread mode,
mbed_official 376:cb4d9db17537 14 ;* priority is Privileged, and the Stack is set to Main.
