00007   * @brief   CMSIS STM32L4xx Device Peripheral Access Layer Header File.
00008   *
00009   *          The file is the unique include file that the application programmer
00010   *          is using in the C source code, usually in main.c. This file contains:
00011   *           - Configuration section that allows to select:
00012   *              - The STM32L4xx device used in the target application
00013   *              - To use or not the peripheral�s drivers in application code(i.e.
00014   *                code will be based on direct access to peripheral�s registers
00015   *                rather than drivers API), this option is controlled by
00016   *                "#define USE_HAL_DRIVER"
