/** @brief Macro to configure the RTC clock (RTCCLK).

  *         access using the Power Backup Access macro before to configure
  *         the RTC clock source (to be done once after reset).    
  * @note   Once the RTC clock is configured it cannot be changed unless the  
  *         Backup domain is reset using @ref __HAL_RCC_BACKUPRESET_FORCE() macro, or by
  *         a Power On Reset (POR).
  *
  * @param  __RTC_CLKSOURCE__ specifies the RTC clock source.
  *          This parameter can be one of the following values:
  *             @arg @ref RCC_RTCCLKSOURCE_NO_CLK No clock selected as RTC clock
  *             @arg @ref RCC_RTCCLKSOURCE_LSE LSE selected as RTC clock
  *             @arg @ref RCC_RTCCLKSOURCE_LSI LSI selected as RTC clock
  *             @arg @ref RCC_RTCCLKSOURCE_HSE_DIV32 HSE clock divided by 32
  * @note   If the LSE or LSI is used as RTC clock source, the RTC continues to
  *         work in STOP and STANDBY modes, and can be used as wakeup source.
  *         However, when the LSI clock and HSE clock divided by 32 is used as RTC clock source,
  *         the RTC cannot be used in STOP and STANDBY modes.
  * @note   The system must always be configured so as to get a PCLK frequency greater than or
  *             equal to the RTCCLK frequency for a proper operation of the RTC.
