- * @version V2.1.0
- * @date 19-June-2014
- * @brief STM32F429xx Devices vector table for Atollic TrueSTUDIO 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 Cortex-M4 processor is in Thread mode,
- * priority is Privileged, and the Stack is set to Main.

- * This file provides two functions and one global variable to be called from

- * - 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.

- * @brief Update SystemCoreClock variable 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 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 stm32f4xx_hal_conf.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 stm32f4xx_hal_conf.h file (its value
- * depends on the application requirements), 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.
