RTC Interrupt Issue

Hi All,

I am using PCF2127 RTC for my project and I am having issue with interrupt.

Enabling Minute interrupt using MI bit field in Control1 register. But MSF bit filed in Control2 register is always 0.

Interrupt signal is high in normal condition and the signal is going to low when interrupt generated.

But the MSF bit field is 0 and it’s not 1 when interrupt generated.

I am facing same issue with seconds interrupt, alarm interrupt.

Looking forward for your prompt reply

Best Regards,

Yusup Khan

Hi Yusup,

I have never heard of such a problem and if the interrupt is generated the corresponding flag must be set.

Best regards,

Tomas
