7   *          The file is the unique include file that the application programmer
8   *          is using in the C source code, usually in main.c. This file contains:
9   *           - Configuration section that allows to select:
10   *              - The STM32C0xx device used in the target application
11   *              - To use or not the peripherals drivers in application code(i.e.
12   *                code will be based on direct access to peripherals registers
13   *                rather than drivers API), this option is controlled by
14   *                "#define USE_HAL_DRIVER"
