The default value for the four Password Value (PWV) is all 1s (FF FF FF FFh). The intent is to provide a manufacturer with a security
feature to protect the Configuration register, Alarm registers, User EEPROM, ETC and Event Counter registers, and the Password
Setting (PWV). The customer is not able to alter the Configuration register, Alarm registers, User EEPROM, ETC or Event Counter
registers, or Password Setting if the password conditions are not met.

Memory Type
EEPROM, Nonvolatile
There are 16 bytes of user-programmable EEPROM memory. User memory is set to read-only if the correct password is not
entered into the Password Entry bytes. If the correct password is entered into the Password Entry bytes, the data can be written
to the User Memory and stored in EEPROM with the correct I2C write command. The User Memory locations can be read regard-
less of the password protection.
