Initialization the Serial Interface to the EEPROM

To prevent unexpected behavior of he EEPROM and its interface it is good practice to use an

initialization sequence after any reset of the circuit. This is performed by writing:

to the serial interface. If the EEPROM acknowledges this sequence it is in a defined state.

Maybe it is necessary to perform this sequence twice.
