PCF8523TK reference circuit connection

[zesun]

I am testing RTC PCF8523TK. This is the first time for me to deal with RTC. Could anyone provide a reference circuit for this module? Basically, I am not sure how to deal with the INT1/CLKOUT pin.

Thanks in advance.

For your question, you could download file UM10760 for the reference design and you also could get the INT1/CLOCL pin application solution.
You could get this file from this link.
