/** @brief Macro to configure the RTC clock (RTCCLK).
* @note As the RTC clock configuration bits are in the Backup domain and write
* access is denied to this domain after reset, you have to enable write
* 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.
