* @brief STM32L151XC Devices vector table for
* Atollic toolchain.
* This module performs:
* - Set the initial SP
* - Set the initial PC == Reset_Handler,
* - Set the vector table entries with the exceptions ISR address
* - Configure the clock system
* - Branches to main in the C library (which eventually
* calls main()).
* After Reset the Cortex-M3 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.

* @file system_stm32l1xx.c
* @author MCD Application Team
* @version V2.2.0
* @date 01-July-2016
* @brief CMSIS Cortex-M3 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_stm32l1xx.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 24 MHz clock) | (internal 16 MHz)
* | 2- PLL_HSE_XTAL |
* | (external 24 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 | NO
*-----------------------------------------------------------------------------

* - If SYSCLK source is MSI, SystemCoreClock will contain the MSI

* - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_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 stm32l1xx.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 stm32l1xx.h file (default value
* 8 MHz), user has to ensure that HSE_VALUE is same as the real
