__STATIC_INLINE void LL_RCC_SetRTCClockSource

(

uint32_t

Source

)

Set RTC Clock Source.

Note:

Once the RTC clock source has been selected, it cannot be changed anymore unless the Backup domain is reset, or unless a failure is detected on LSE (LSECSSD is set). The BDRST bit can be used to reset them.

Reference Manual to LL API cross reference:

Parameters:

Source

This parameter can be one of the following values: LL_RCC_RTC_CLKSOURCE_NONE LL_RCC_RTC_CLKSOURCE_LSE LL_RCC_RTC_CLKSOURCE_LSI LL_RCC_RTC_CLKSOURCE_HSE

Return values:

None
