asserted)
RTCx: RTC Instance
Polarity: This parameter can be one of the following values:
LL_RTC_OUTPUTPOLARITY_PIN_HIGH
LL_RTC_OUTPUTPOLARITY_PIN_LOW
None:
Bit is write-protected. LL_RTC_DisableWriteProtection
function should be called before.
CR POL LL_RTC_SetOutputPolarity
__STATIC_INLINE uint32_t LL_RTC_GetOutputPolarity
(RTC_TypeDef * RTCx)
Get Output polarity.
RTCx: RTC Instance
Returned: value can be one of the following values:
LL_RTC_OUTPUTPOLARITY_PIN_HIGH
LL_RTC_OUTPUTPOLARITY_PIN_LOW
CR POL LL_RTC_GetOutputPolarity
__STATIC_INLINE void LL_RTC_EnableRefClock
(RTC_TypeDef * RTCx)
Enable RTC_REFIN reference clock detection (50 or 60 Hz)
RTCx: RTC Instance
None:
Bit is write-protected. LL_RTC_DisableWriteProtection
function should be called before.
It can be written in initialization mode only
(LL_RTC_EnableInitMode function)
CR REFCKON LL_RTC_EnableRefClock
__STATIC_INLINE void LL_RTC_DisableRefClock
(RTC_TypeDef * RTCx)
Disable RTC_REFIN reference clock detection (50 or 60 Hz)
RTCx: RTC Instance
