+  * @file      startup_stm32f030x6.s
+  * copied from: STM32Cube/Drivers/CMSIS/Device/ST/STM32F0xx/Source/Templates/gcc
+  * @author    MCD Application Team
+  * @version   V2.3.1
+  * @date      04-November-2016
+  * @brief     STM32F030x4/STM32F030x6 devices vector table for Atollic TrueSTUDIO 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 Cortex-M0 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.
