  * @brief   CMSIS STM32G0xx Device Peripheral Access Layer Header File.
  *
  *          The file is the unique include file that the application programmer
  *          is using in the C source code, usually in main.c. This file contains:
  *           - Configuration section that allows to select:
  *              - The STM32G0xx device used in the target application
  *              - To use or not the peripherals drivers in application code(i.e.
  *                code will be based on direct access to peripherals registers
  *                rather than drivers API), this option is controlled by
  *                "#define USE_HAL_DRIVER"
