* @author MCD Application Team
* @version V1.5.0
* @date 05-December-2014
* @brief STM32F072 Devices vector table for RIDE7 toolchain.
* @brief STM32F072x8/STM32F072xB devices vector table for GCC toolchain.
* This module performs:
* - Set the initial SP
* - Set the initial PC == Reset_Handler,
* - Set the vector table entries with the exceptions ISR address
* - Configure the system clock
* - 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.
