Aman,

I understand that you desperately seek help but please don't post directly to other 8052.com members, it's not too likely anybody who alredy did not answer in the forum can give you relevant help - contrary, this might make some of the members unnecesarily angry.

On the other hand, Andy is right - first, try to ask a specific question. It is unlikely you will get a relevant answer unless you provide details - what is your HW, what have you done already, what are your findings and how they differ from your expectations.

I have no = zero experience with the said timekeeper chip so I cannot help you with the details. However, the first result google gave me was the datasheet and the second was an appnote on interfacing this chip to 8051, including sources. Have you read that?
