Datasheet p3:
Write cycle time: 5ms
Is that the 'dead' time before another write can take place?
I have not included code for checking the flag telling the WRITE is finished but if I take in account the stated 5ms, I should be safe, shouldn't I?

So I do not need to wait after a read? Okay, I gues it is beacause no data is modified but why should it take more time to write than to read?
