+// Notes
+//
+// - The pins mentionned Px_y_ALTz are alternative possibilities which use other
+//   HW peripheral instances. You can use them the same way as any other "normal"
+//   pin (i.e. PwmOut pwm(PA_7_ALT0);). These pins are not displayed on the board
+//   pinout image on mbed.org.
+//
+// - The pins which are connected to other components present on the board have
+//   the comment "Connected to xxx". The pin function may not work properly in this
+//   case. These pins may not be displayed on the board pinout image on mbed.org.
+//   Please read the board reference manual and schematic for more information.

+  ******************************************************************************
+  * @file    system_stm32l4xx.c
+  * @author  MCD Application Team
+  * @version V1.3.1
+  * @date    21-April-2017
+  * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File
+  *
+  *   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_stm32l4xx.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.
+  *
+  *   After each device reset the MSI (4 MHz) is used as system clock source.
+  *   Then SystemInit() function is called, in "startup_stm32l4xx.s" file, to
+  *   configure the system clock before to branch to main program.
+  *
+  *   This file configures the system clock as follows:
+  *=============================================================================
+  * System clock source                | 1- PLL_HSE_EXTC        | 3- PLL_HSI
+  *                                    | (external 8 MHz clock) | (internal 16 MHz)
+  *                                    | 2- PLL_HSE_XTAL        | or PLL_MSI
+  *                                    | (external 8 MHz xtal)  | (internal 4 MHz)
+  *-----------------------------------------------------------------------------
+  * SYSCLK(MHz)                        | 48                     | 80
+  *-----------------------------------------------------------------------------
+  * AHBCLK (MHz)                       | 48                     | 80
+  *-----------------------------------------------------------------------------
+  * APB1CLK (MHz)                      | 48                     | 80
+  *-----------------------------------------------------------------------------
+  * APB2CLK (MHz)                      | 48                     | 80
+  *-----------------------------------------------------------------------------
+  * USB capable (48 MHz precise clock) | YES                    | NO
