This register is used in unmanaged mode only. Before requesting that the ZL50418 updates the EEPROM device,
the correct checksum needs to be calculated and written into this checksum register. The checksum formula is
When the ZL50418 boots from the EEPROM the checksum is calculated and the value must be zero. If the
checksum is not zeroed the ZL50418 does not start and pin CHECKSUM_OK is set to zero.
