;* File Name : startup_stm32l152xe.s
;* Author : MCD Application Team
;* Version : V2.0.0
;* Date : 5-September-2014
;* Description : STM32L152XE Devices vector for EWARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == __iar_program_start,
;* - Set the vector table entries with the exceptions ISR
;* address.
;* - Configure the system clock
;* - 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.

; The vector table is normally located at address 0.
; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.
; The name "__vector_table" has special meaning for C-SPY:
; it is where the SP start value is found, and the NVIC vector

* @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 8 MHz clock) | (internal 16 MHz)
* | 2- PLL_HSE_XTAL |
* | (external 8 MHz xtal) |
*-----------------------------------------------------------------------------
* SYSCLK(MHz) | 24 | 32
*-----------------------------------------------------------------------------
* AHBCLK (MHz) | 24 | 32
*-----------------------------------------------------------------------------
* APB1CLK (MHz) | 24 | 32
*-----------------------------------------------------------------------------
* APB2CLK (MHz) | 24 | 32
*-----------------------------------------------------------------------------
* USB capable (48 MHz precise clock) | YES | NO

* @brief Update SystemCoreClock according to Clock Register Values
* The SystemCoreClock variable contains the core clock (HCLK), it can
* be used by the user application to setup the SysTick timer or configure
* 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 MSI, SystemCoreClock will contain the MSI
* value as defined by the MSI range.
*
* - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)
*
* - 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
* frequency of the crystal used. Otherwise, this function may
* have wrong result.
*
* - The result of this function could be not correct when using fractional
* value for HSE crystal.
* @param None
