;* File Name : startup_stm32f070xb.s
;* Author : MCD Application Team
;* Description : STM32F070x8/STM32F070xB 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 CortexM0 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.
