The EEPROM values for registers 0x60h-0x80h must all be programmed by the end user during production programming. Most EEPROM values will have a default value of 0x00h from the Maxim Factory. The RSGain register is calibrated differently for each IC. It can be calibrated by the user when the IC is assembled into the board, but the Factory RSGain value is backed up in register addresses 0xB0h-0B1h in case it needs to be restored.
