  4.   * @author  MCD Application Team
  5.   * @brief   CMSIS STM32L1xx Device Peripheral Access Layer Header File.
  6.   *
  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 STM32L1xx device used in the target application
  11.   *              - To use or not the peripheralÂ’s drivers in application code(i.e.
  12.   *                code will be based on direct access to peripheralÂ’s registers
  13.   *                rather than drivers API), this option is controlled by
  14.   *                "#define USE_HAL_DRIVER"
  15.   *
