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
