Stop/Quit a Write Operation to EEPROM

Hi,

How can I stop an operation before it's complete?
Let's say I want to write to EEPROM. It takes x milliseconds to perform the write operation. At t=x/2 I want to stop the operation and read out the memory.

I know how to read and write to EEPROM. But I don't how to stop/quit the operation after it got started.

I appreciate any help!

Thanks!

internal/PSI/I2C EEPROM??

most of the time is a latency (few milliseconds) that is needed to actually write it.
Cant be interrupted, its sort of atomic AFAIK..
