I have been looking at reading and writing from eeprom, it seems quite simple.

It mentions EEPROM write time in the manual for the language I am using, what is the significance of this?

What time should I choose for writing byte values to the eeprom memory?

Thanks

John
 

What EEPROM are you talking about?, the internal data EEPROM?, or an external I2C EEPROM?.
 
You have to set the 'WR' bit to start the write, when the write is complete the bit will be cleared in hardware. So just poll the bit and wait until it is clear.

Yes, there's no need to add a timed delay, the procedure is given in the datasheet - if you're using a high level language to write your code, the compiler should produce the correct code for you.
