Functions
static uint32_t	UTILS_GetPLLOutputFrequency (uint32_t PLL_InputFrequency, LL_UTILS_PLLInitTypeDef *UTILS_PLLInitStruct)
	Function to check that PLL can be modified.
static ErrorStatus	UTILS_EnablePLLAndSwitchSystem (uint32_t SYSCLK_Frequency, LL_UTILS_ClkInitTypeDef *UTILS_ClkInitStruct)
	Function to enable PLL and switch system clock to PLL.
static ErrorStatus	UTILS_IsPLLsReady (void)
	Check that all PLLs are ready therefore configuration can be done.
void	LL_Init1msTick (uint32_t CPU_Frequency)
	This function configures the Cortex-M SysTick source to have 1ms time base.
void	LL_mDelay (uint32_t Delay)
	This function provides accurate delay (in milliseconds) based on SysTick counter flag.
void	LL_SetSystemCoreClock (uint32_t CPU_Frequency)
	This function sets directly SystemCoreClock CMSIS variable.
ErrorStatus	LL_PLL_ConfigSystemClock_HSI (LL_UTILS_PLLInitTypeDef *UTILS_PLLInitStruct, LL_UTILS_ClkInitTypeDef *UTILS_ClkInitStruct)
	This function configures system clock at maximum frequency with HSI as clock source of the PLL.
