I doubt is anyone has that code for you, but you might explain in more detail what you are trying to do.

The RTC chip has a data sheet that describes it operation? Do you have it and do you understand it?

This makes no sense. If your microprocessor has an I2C interface, it also has a data sheet that describes how to pass data through it.

Assembler code is different for every microprocessor and application.

If you are aware of C language and going to write code in C then you may be get some reference code for the I2C.
