Functions
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.
ErrorStatus	LL_PLL_ConfigSystemClock_HSE (uint32_t HSEFrequency, uint32_t HSEBypass, LL_UTILS_PLLInitTypeDef *UTILS_PLLInitStruct, LL_UTILS_ClkInitTypeDef *UTILS_ClkInitStruct)
	This function configures system clock with HSE as clock source of the PLL.
ErrorStatus	LL_SetFlashLatency (uint32_t HCLK_Frequency)
	Update number of Flash wait states in line with new frequency and current voltage range.
