__STATIC_INLINE void LL_RCC_DisableRTC

(

void

)

None

Definition at line 3672 of file stm32l4xx_ll_rcc.h.

__STATIC_INLINE void LL_RCC_ForceBackupDomainReset

(

void

)

Force the Backup domain reset.

Reference Manual to LL API cross reference:

BDCR BDRST LL_RCC_ForceBackupDomainReset

Return values:

None

Definition at line 3702 of file stm32l4xx_ll_rcc.h.

__STATIC_INLINE uint32_t LL_RCC_GetRTCClockSource

(

void

)

Get RTC Clock Source.

Reference Manual to LL API cross reference:

BDCR RTCSEL LL_RCC_GetRTCClockSource

Return values:

Returned

value 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_DIV32

Definition at line 3662 of file stm32l4xx_ll_rcc.h.

__STATIC_INLINE uint32_t LL_RCC_IsEnabledRTC

(

void

)

Check if RTC has been enabled or not.

Reference Manual to LL API cross reference:

BDCR RTCEN LL_RCC_IsEnabledRTC

Return values:

State

of bit (1 or 0).

Definition at line 3692 of file stm32l4xx_ll_rcc.h.

__STATIC_INLINE void LL_RCC_ReleaseBackupDomainReset

(

void

)

Release the Backup domain reset.

Reference Manual to LL API cross reference:

BDCR BDRST LL_RCC_ReleaseBackupDomainReset

Return values:

None

Definition at line 3712 of file stm32l4xx_ll_rcc.h.

__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:

BDCR RTCSEL LL_RCC_SetRTCClockSource

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_DIV32

Return values:

None
