RTC_TamperSamplingFreq_RTCCLK_Div4096: Each of the tamper inputs are sampled with a frequency = RTCCLK / 4096
RTC_TamperSamplingFreq_RTCCLK_Div2048: Each of the tamper inputs are sampled with a frequency = RTCCLK / 2048
RTC_TamperSamplingFreq_RTCCLK_Div1024: Each of the tamper inputs are sampled with a frequency = RTCCLK / 1024
RTC_TamperSamplingFreq_RTCCLK_Div512: Each of the tamper inputs are sampled with a frequency = RTCCLK / 512
RTC_TamperSamplingFreq_RTCCLK_Div256: Each of the tamper inputs are sampled with a frequency = RTCCLK / 256

Return values

None

Definition at line 2196 of file stm32f4xx_rtc.c.

void RTC_TamperTriggerConfig	(	uint32_t	RTC_Tamper,
		uint32_t	RTC_TamperTrigger
	)

Configures the select Tamper pin edge.

Parameters

RTC_Tamper Selected tamper pin. This parameter can be RTC_Tamper_1.

RTC_TamperTrigger

Specifies the trigger on the tamper pin that stimulates tamper event. This parameter can be one of the following values:
