Device Addressing
Following a start condition the master must output the address of
the slave it is accessing. The most significant four bits of the slave
address are those of the device type identifier (see Figure 4) This
is fixed as 1010 for all EEPROM devices.

Data Validity (Figure 1).
Start and Stop Definition (Figure 2).
All IIC EEPROMs use an internal protocol that defines a PAGE
BLOCK size of 2K bits (for Byte addresses 00 through FF).
