Johan,

 Yes, You don't want anything to happen when writing to the EEPROM.
 If an interrupt happened in the middle of the write process, you
 could have scrambled data.  The write is supposed to be (and is)
 controlled by an independent on chip wirte timer.  But better to
 be safe than sorry.

                                            Regards,

                                              Jim
