Functions
static void	SetSysClock (void)
	Configures the System clock source, PLL Multiplier and Divider factors, AHB/APBx prescalers and Flash settings This function should be called only once the RCC clock configuration is reset to the default reset state (done in SystemInit() function). More...
void	SystemInit (void)
	Setup the microcontroller system Initialize the Embedded Flash Interface, the PLL and update the SystemFrequency variable. More...
void	SystemCoreClockUpdate (void)
	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. More...
