+ * @author MCD Application Team
+ * @version V1.0.0
+ * @date 04-September-2012
+ * @brief CMSIS Cortex-M4 Device Peripheral Access Layer Header File.
+ * This file contains all the peripheral registers definitions, bits
+ * definitions and memory mapping for STM32F30x devices.
+ *
+ * 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 device used in the target application
+ * - To use or not the peripheral’s drivers in application code(i.e.
+ * code will be based on direct access to peripheral’s registers
+ * rather than drivers API), this option is controlled by
+ * "#define USE_STDPERIPH_DRIVER"
+ * - To change few application-specific parameters such as the HSE
+ * crystal frequency
+ * - Data structures and the address mapping for all peripherals
+ * - Peripheral registers declarations and bits definition
+ * - Macros to access peripheral registers hardware
+ *
