+ * @brief CMSIS Cortex-M0 Device Peripheral Access Layer System Source File.
+ *
+ * 1. This file provides two functions and one global variable to be called from
+ * user application:
+ * - SystemInit(): This function is called at startup just after reset and
+ * before branch to main program. This call is made inside
+ * the "startup_stm32f0xx.s" file.
+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+ * by the user application to setup the SysTick
+ * timer or configure other parameters.
+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+ * Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to
+ * configure the system clock before to branch to main program.
+ *
+ * 3. This file configures the system clock as follows:
+ *=============================================================================
+ * Supported STM32F0xx device
+ *-----------------------------------------------------------------------------
+ * System Clock source | HSI
+ *-----------------------------------------------------------------------------
+ * SYSCLK(Hz) | 8000000
+ *-----------------------------------------------------------------------------
+ * HCLK(Hz) | 8000000
+ *-----------------------------------------------------------------------------
+ * AHB Prescaler | 1
+ *-----------------------------------------------------------------------------
+ * APB1 Prescaler | 1

+ * HID Class Description
+ * ===================================================================
+ * This module manages the HID class V1.11 following the "Device Class Definition
+ * for Human Interface Devices (HID) Version 1.11 Jun 27, 2001".
+ * This driver implements the following aspects of the specification:
+ * - The Boot Interface Subclass
+ * - The Mouse protocol
+ * - Usage Page : Generic Desktop
+ * - Usage : Joystick
+ * - Collection : Application
+ *
+ * @note In HS mode and when the DMA is used, all variables and data structures
+ * dealing with the DMA during the transaction process should be 32-bit aligned.
