* @brief STM32F030x4/STM32F030x6 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
* - Branches to main in the C library (which eventually

* After Reset the Cortex-M0 processor is in Thread mode,
