+  * @author  MCD Application Team
+  * @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:

+  *         other parameters.

+  * @note   Each time the core clock (HCLK) changes, this function must be called
+  *         to update SystemCoreClock variable value. Otherwise, any configuration
+  *         based on this variable will be incorrect.
+  *
+  * @note   - The system frequency computed by this function is not the real
+  *           frequency in the chip. It is calculated based on the predefined
+  *           constant and the selected clock source:
+  *
+  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(**) / HSI division factor
+  *
+  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(***)
+  *
+  *           - If SYSCLK source is LSI, SystemCoreClock will contain the LSI_VALUE
+  *
+  *           - If SYSCLK source is LSE, SystemCoreClock will contain the LSE_VALUE
+  *
+  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(***)
+  *             or HSI_VALUE(*) multiplied/divided by the PLL factors.
+  *
+  *         (**) HSI_VALUE is a constant defined in stm32g0xx_hal_conf.h file (default value
+  *              16 MHz) but the real value may vary depending on the variations
+  *              in voltage and temperature.
+  *
+  *         (***) HSE_VALUE is a constant defined in stm32g0xx_hal_conf.h file (default value
+  *              8 MHz), user has to ensure that HSE_VALUE is same as the real
+  *              frequency of the crystal used. Otherwise, this function may
+  *              have wrong result.
+  *
+  *         - The result of this function could be not correct when using fractional

+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M0+ processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.
