ALRAF bit is set in ISR register but doesn,t execute the rtc-irq handler.

i enabled NVIC_RTC.

What's the configuration? MCU? CubeMX and/or LL-drivers in use ?

Did you also enable the EXTI line for RTC alarm?

Chronically vague, provide context.

The bug is obvious: you just need to set the 3rd bit 38th line down on the 2nd page of your 8th function about 2/3 logic high. As now, it is not high enough.

Which IDE are you using ?

can you check the registers with single step ?

You could read the Reference manual to find all the register descriptions.

your problem would be in there, as a guess.

void RTC_ALRMAR_SET()

{

RTC->WPR = 0xCA;

RTC->WPR = 0x53;

RTC->CR &=~ RTC_CR_ALRAE;

while((RTC->ISR & RTC_ISR_ALRAWF) != RTC_ISR_ALRAWF)

{

}

RTC->ALRMAR = RTC_ALRMAR_MSK4 | RTC_ALRMAR_MSK3 | RTC_ALRMAR_MSK2 | 1<<30(Week day selection mask) | 1<<4(set Second tens in BCD format.);

RTC->CR = RTC_CR_ALRAIE | RTC_CR_ALRAE;

RTC->WPR = 0xFE;

RTC->WPR = 0x64;

}

trying to get interrupt at 10 sec but not working
