* @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) | 84 | 84
|
||||
*-----------------------------------------------------------------------------
|
||||
* AHBCLK (MHz) | 84 | 84
|
||||
*-----------------------------------------------------------------------------
|
||||
* APB1CLK (MHz) | 42 | 42
|
||||
*-----------------------------------------------------------------------------
|
||||
* APB2CLK (MHz) | 84 | 84
|
||||
*-----------------------------------------------------------------------------
|
||||
* USB capable (48 MHz precise clock) | YES | NO
