* Each EEPROM block is read/write until locked by the LOCK command, after which it is read-only.
PROTECTION REGISTER
The protection register consists of flags that indicate protection circuit status and switches that give conditional
control over the charging and discharging paths. Bits OV, UV, COC, and DOC are set when corresponding
protection conditions occur and remain set until cleared by the host system. The default values of the CE and DE
bits of the protection register are stored in lockable EEPROM in the corresponding bits in address 30h. A recall
data command for EEPROM block 1 recalls the default values into CE and DE. Figure 10 shows the format of the
protection register. The function of each bit is described in detail in the following paragraphs.
