None.
void RTC_OutputConfig ( uint32_t RTC_Output, uint32_t
RTC_OutputPolarity)
Configures the RTC output source (AFO_ALARM).

RTC_Output : Specifies which signal will be routed to the
RTC output. This parameter can be one of the following
values:

RTC_Output_Disable :

RTC_Output_AlarmA :
output

RTC_Output_AlarmB :
output

RTC_Output_WakeUp :
output

RTC_OutputPolarity : Specifies the polarity of the output
signal. This parameter can be one of the following:

RTC_OutputPolarity_High :
when the ALRAF/ALRBF/WUTF is high (depending on
OSEL)

RTC_OutputPolarity_Low :
the ALRAF/ALRBF/WUTF is high (depending on OSEL)

None.

