A -> acknowledge, N -> no acknowledge; HB: high byte; LB: low byte, R: row address
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.
