;* Date : 19-June-2014
|
||||
;* Description : STM32F411xExx devices vector table for MDK-ARM_MICRO toolchain.
|
||||
;* 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 CortexM4 processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

|

;* Description : STM32F411xExx devices vector table for MDK-ARM_STD toolchain.
|
||||
;* 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 CortexM4 processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

;* Date : 19-June-2014
|
||||
;* Description : STM32F411xExx devices vector table 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-M4 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:

* @brief CMSIS STM32F4xx Device Peripheral Access Layer Header File.
|
||||
*
|
||||
* The file is the unique include file that the application programmer
|
||||
* is using in the C source code, usually in main.c. This file contains:
|
||||
* - Configuration section that allows to select:
|
||||
* - The STM32F4xx device used in the target application
|
||||
* - To use or not the peripheral’s drivers in application code(i.e.
|
||||
* code will be based on direct access to peripheral’s registers
|
||||
* rather than drivers API), this option is controlled by
|
||||
* "#define USE_HAL_DRIVER"

|

*
|

* 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_stm32f4xx.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) | 100 | 100
|
||||
*-----------------------------------------------------------------------------
|
||||
* AHBCLK (MHz) | 100 | 100
|
||||
*-----------------------------------------------------------------------------
|
||||
* APB1CLK (MHz) | 50 | 50
|
||||
*-----------------------------------------------------------------------------
|
||||
* APB2CLK (MHz) | 100 | 100
|
||||
*-----------------------------------------------------------------------------
|
||||
* USB capable (48 MHz precise clock) | NO | NO

* (*) HSI_VALUE is a constant defined in stm32f4xx_hal_conf.h file (default value
