2-Cell, Stand-Alone, Li+ Fuel-Gauge IC with
Protector and Optional SHA-1 Authentication
EEPROM Register
The EEPROM register provides access control of the EEPROM blocks. EEPROM blocks can be locked to prevent
alteration of data within the block. Locking a block disables write access to the block. Once a block is locked, it can-
not be unlocked. Read access to EEPROM blocks is unaffected by the lock/unlock status.

Bit 7: EEPROM Copy Flag (EEC). A 1 in this read-only bit indicates that a Copy Data command is in progress.
While this bit is high, writes to EEPROM addresses are ignored. A 0 value in this bit indicates that data can be written
to unlocked EEPROM.
Bit 6: EEPROM Lock Enable (LOCK). When the LOCK bit is 0, the Lock command is ignored. Writing a 1 to this bit
enables the Lock command. After setting the LOCK bit, the Lock command must be issued as the next command,
else the LOCK bit is reset to 0. After the lock operation is completed, the LOCK bit is reset to 0. The LOCK bit is a
volatile R/ W bit, initialized to 0 upon POR.
Bits 5 to 2: Reserved.
Bit 1: Parameter EEPROM Block 1 Lock Flag (BL1). A 1 in this read-only bit indicates that EEPROM block 1
(addresses 60h to 80h) is locked (read-only), while a 0 indicates block 1 is unlocked (read/write).
Bit 0: User EEPROM Block 0 Lock Flag (BL0). A 1 in this read-only bit indicates that EEPROM block 0 (addresses
20h to 2Fh) is locked (read-only), while a 0 indicates block 0 is unlocked (read/write).
