* @note As the RTC clock configuration bits are in the RTC domain and write
* access is denied to this domain after reset, you have to enable write
* access using PWR_RTCAccessCmd(ENABLE) function 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 RTC
* is reset using RCC_RTCResetCmd function, or by a Power On Reset (POR)
* @note The RTC clock (RTCCLK) is used also to clock the LCD (LCDCLK).
*
* @param RCC_RTCCLKSource: specifies the RTC clock source.
* This parameter can be one of the following values:
* @arg RCC_RTCCLKSOURCE_LSE: LSE selected as RTC clock
* @arg RCC_RTCCLKSOURCE_LSI: LSI selected as RTC clock
* @arg RCC_RTCCLKSOURCE_HSE_DIV2: HSE divided by 2 selected as RTC clock
* @arg RCC_RTCCLKSOURCE_HSE_DIV4: HSE divided by 4 selected as RTC clock
* @arg RCC_RTCCLKSOURCE_HSE_DIV8: HSE divided by 8 selected as RTC clock
* @arg RCC_RTCCLKSOURCE_HSE_DIV16: HSE divided by 16 selected as RTC clock
*
* @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 HSE clock is used as RTC clock source, the RTC
* cannot be used in STOP and STANDBY modes.
* @note The maximum input clock frequency for RTC is 1MHz (when using HSE as
* RTC clock source).
