< Important Notice > The adjusted data in AKM factory are stored in advance at address location (Device

60h) for the offset voltage of the On-chip temperature sensor. If such excessive
temperature stress is to be applied to the AK2572 which exceeds a guaranteed EEPROM data retention
conditions (for 10 years at 85
℃
), it is important to read the pre-determined data in advance and to re-write the
same data back into EEPROM after an exposure to the excessive temperature environment. Even if the
exposure time is shorter than the retention time, any accelerated temperature stress tests (such as baking) are
performed, it is recommended to read the pre-set data first and to re-write it after the test. Access to unused
address locations is not functionally guaranteed. Please refer to Section 9.4, “EEPROM Configuration”.
