The communications protocol is based on the popular two-wire serial interface. Note
that the most significant bit is transmitted first.
Figure 4. Read EEPROM
Note:
The data byte address is internally incremented following the transmission of each data
byte. During a read operation, the address “roll over” is from the last byte of the current
zone to the first byte of the same zone. If the host is not allowed to read at the specified
address, the device will transmit the corresponding data byte with all bits equal to “0”.
