EricLew 0:d4e5ad7ad71c 7 * @brief CMSIS STM32L4xx Device Peripheral Access Layer Header File.
EricLew 0:d4e5ad7ad71c 8 *
EricLew 0:d4e5ad7ad71c 9 * The file is the unique include file that the application programmer
EricLew 0:d4e5ad7ad71c 10 * is using in the C source code, usually in main.c. This file contains:
EricLew 0:d4e5ad7ad71c 11 * - Configuration section that allows to select:
EricLew 0:d4e5ad7ad71c 12 * - The STM32L4xx device used in the target application
EricLew 0:d4e5ad7ad71c 13 * - To use or not the peripheral�s drivers in application code(i.e.
EricLew 0:d4e5ad7ad71c 14 * code will be based on direct access to peripheral�s registers
EricLew 0:d4e5ad7ad71c 15 * rather than drivers API), this option is controlled by
EricLew 0:d4e5ad7ad71c 16 * "#define USE_HAL_DRIVER"
