* @note After enabling the LSE (RCC_LSE_ON or RCC_LSE_BYPASS), the application
* software should wait on LSERDY flag to be set indicating that LSE clock
* is stable and can be used to clock the RTC.
* @param __STATE__ specifies the new state of the LSE.
* This parameter can be one of the following values:
* @arg RCC_LSE_OFF: turn OFF the LSE oscillator, LSERDY flag goes low after
* 6 LSE oscillator clock cycles.
* @arg RCC_LSE_ON: turn ON the LSE oscillator.
