+ * @brief CMSIS Cortex-M0+ 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_stm32l0xx.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.
+ *
+ * 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 |
+ * | (external 8 MHz xtal) |
+ *-----------------------------------------------------------------------------
+ * SYSCLK(MHz) | 32 | 32
+ *-----------------------------------------------------------------------------
+ * AHBCLK (MHz) | 32 | 32
+ *-----------------------------------------------------------------------------
+ * APB1CLK (MHz) | 32 | 32
+ *-----------------------------------------------------------------------------
+ * APB2CLK (MHz) | 32 | 32
+ *-----------------------------------------------------------------------------
+ * USB capable (48 MHz precise clock) | YES | YES
