The 2-kbit EEPROM is organized as either 256 bytes of 8 bits each (byte mode), or
16 pages of 16 bytes each (page mode). Accessing the EEPROM in byte mode or page
mode is automatic; partial page write of 2 bytes, 4 bytes, or 8 bytes is also supported.
Communication with the EEPROM is via the 2-wire serial I
