- ******************************************************************************
- * @file system_stm32l1xx.c
- * @author MCD Application Team
- * @version V1.2.0
- * @date 11-July-2014
- * @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
- * This file contains the system clock configuration for STM32L1xx Ultra
- * Low power devices, and is generated by the clock configuration
- * tool STM32L1xx_Clock_Configuration_V1.2.0.xls
- *
- * 1. This file provides two functions and one global variable to be called from
- * user application:
- * - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
- * and Divider factors, AHB/APBx prescalers and Flash settings),
- * depending on the configuration made in the clock xls tool.
- * This function is called at startup just after reset and
- * before branch to main program. This call is made inside
- * the "startup_stm32l1xx_xx.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 MSI (2.1 MHz Range) is used as system clock source.
- * Then SystemInit() function is called, in "startup_stm32l1xx_xx.s" file, to
- * configure the system clock before to branch to main program.
- *
- * 3. If the system clock source selected by user fails to startup, the SystemInit()
- * function will do nothing and MSI still used as system clock source. User can
- * add some code to deal with this issue inside the SetSysClock() function.
- *
- * 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
- * in "stm32l1xx.h" file. When HSE is used as system clock source, directly or
- * through PLL, and you are using different crystal you have to adapt the HSE
- * value to your own configuration.
- *
- * 5. This file configures the system clock as follows:
- *=============================================================================
- * System Clock Configuration
- *=============================================================================
- * System Clock source | PLL(HSE)
- *-----------------------------------------------------------------------------
- * SYSCLK | 32000000 Hz

- *-----------------------------------------------------------------------------
- * PLL DIV | 3
- *-----------------------------------------------------------------------------
- * PLL MUL | 24
- *-----------------------------------------------------------------------------
