PRODUCTION DATA.
After power up, the EEPROM is locked for programming by default. When locked, all writes to the EEPROM are ignored. In order to program the EEPROM, first unlock the memory for programming by writing logic 1 to NUS (bit 0 in the temperature register) using a regular write communication. EEPROM locations are readable whether locked or unlocked. Locking the EEPROM by default is a protection provided to prevent unintentional triggering of EEPROM programming during normal device operations.
