is defined in the Device Overview chapter and is reflected in the INITEE register contents defined in the
INT block description chapter. Shown within the EEPROM array are: a protection/reserved field and
user-defined EEPROM protected sectors. The 16-byte protection/reserved field is located in the EEPROM
array from address 0x07F0 to 0x07FF. A description of this protection/reserved field is given in
