After each device reset the HSI (8 MHz) is used as system clock source. + * Then SystemInit() function is called, in "startup_stm32f3xx.s" file, to + * configure the system clock before to branch to main program. + * + * 3. This file configures the system clock as follows: + *============================================================================= + * Supported STM32F3xx device + *----------------------------------------------------------------------------- + * System Clock source | HSI + *----------------------------------------------------------------------------- + * SYSCLK(Hz) | 8000000 + *----------------------------------------------------------------------------- + * HCLK(Hz) | 8000000 + *----------------------------------------------------------------------------- + * AHB Prescaler | 1 + *----------------------------------------------------------------------------- + * APB2 Prescaler | 1 + *----------------------------------------------------------------------------- + * APB1 Prescaler | 1 + *----------------------------------------------------------------------------- + * USB Clock | DISABLE + *----------------------------------------------------------------------------- + *============================================================================= + ****************************************************************************** + * @attention + * + *
