函数说明

◆ RTC_ClearFlag()

void RTC_ClearFlag ( uint16_t RTC_FLAG )

Clears the RTC's pending flags.

参数

RTC_FLAG

specifies the flag to clear. This parameter can be any combination of the following values:

RTC_FLAG_RSF: Registers Synchronized flag. This flag is cleared only after an APB reset or an APB Clock stop.
RTC_FLAG_OW: Overflow flag
RTC_FLAG_ALR: Alarm flag
RTC_FLAG_SEC: Second flag

返回值

None

◆ RTC_ClearITPendingBit()

void RTC_ClearITPendingBit ( uint16_t RTC_IT )

Clears the RTC's interrupt pending bits.

参数

RTC_IT

specifies the interrupt pending bit to clear. This parameter can be any combination of the following values:

RTC_IT_OW: Overflow interrupt
RTC_IT_ALR: Alarm interrupt
RTC_IT_SEC: Second interrupt

返回值

None

◆ RTC_GetFlagStatus()

FlagStatus RTC_GetFlagStatus ( uint16_t RTC_FLAG )

Checks whether the specified RTC flag is set or not.

参数

RTC_FLAG

specifies the flag to check. This parameter can be one the following values:

RTC_FLAG_RTOFF: RTC Operation OFF flag
RTC_FLAG_RSF: Registers Synchronized flag
RTC_FLAG_OW: Overflow flag
RTC_FLAG_ALR: Alarm flag
RTC_FLAG_SEC: Second flag

返回值

返回值

The	new state of the RTC_IT (SET or RESET).

◆ RTC_ITConfig()

void RTC_ITConfig	(	uint16_t	RTC_IT,
		FunctionalState	NewState
	)

Enables or disables the specified RTC interrupts.

参数

RTC_IT	specifies the RTC interrupts sources to be enabled or disabled. This parameter can be any combination of the following values: RTC_IT_OW: Overflow interrupt RTC_IT_ALR: Alarm interrupt RTC_IT_SEC: Second interrupt
