LTC4281 EEPROM problem


we have a problem with LTC4281. In EEPROM stored 0x55, 0xAA, 0x55, 0xAA ..... values, and it can not be changed over i2c.

RAM registers are changing after i2c transactions by MCU just fine, but EEPROM registers ignore it.

We checked WP pin, it is pulled-down.

Could you please explain how to write to EEPROM registers?
