  * @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_stm32g0xx.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 HSI （8 MHz then 16 MHz） is used as system clock source.
  *   Then SystemInit（） function is called in “startup_stm32g0xx.s“ file to
  *   configure the system clock before to branch to main program.
  *
  *   This file configures the system clock as follows:
  *=============================================================================
  *-----------------------------------------------------------------------------
  *        System Clock source                    | HSI
  *-----------------------------------------------------------------------------
  *        SYSCLK（Hz）                             | 16000000
  *-----------------------------------------------------------------------------
  *        HCLK（Hz）                               | 16000000
  *-----------------------------------------------------------------------------
  *        AHB Prescaler                          | 1
  *-----------------------------------------------------------------------------
  *        APB Prescaler                          | 1
  *-----------------------------------------------------------------------------
  *        HSI Division factor                    | 1
  *-----------------------------------------------------------------------------
  *        PLL_M                                  | 1
  *-----------------------------------------------------------------------------
  *        PLL_N                                  | 8
  *-----------------------------------------------------------------------------
  *        PLL_P                                  | 7

  *        PLL_Q                                  | 2
  *-----------------------------------------------------------------------------
  *        PLL_R                                  | 2
