Description
This register contains the 8-bit EEPROM lock password. This password is used to protect the
register contents from being changed. The EEPROM is always locked. When the EEPROM
downloads its contents to the registers, the password is also downloaded. If the user writes the
same password to this register twice, the EEPROM is unlocked and can be updated. To lock the
EEPROM again, the user must write any value other than the password value into this register.
