in assembly code
@AMJ: you expect an answer to this incomplete question?
The supply:

- For which microcontroller? Each family of microcontrollers has their own assembly language.
- How is the rtc connected to the microcontroller? At least which pins are used, better a schematic.
- Have you searched the relevant internet sources?

- for 8051 microcontroller
- p3.7 SDA and p3.6 SCL
- i would like to knw the exact i2c start,stop,read and write protocols for this pcf8583 rtc to retrieve data (time).
