4.6.2 EEPROM Memory for Setup
The EEPROM is used for setup and configuration data, stored as an alternative to the CMOS-RTC. Option-
ally, the EEPROM setup driver may update the CMOS RTC, if the battery is running down, the checksum
error would appear and stop the system. The capacity of the EEPROM is 2048 Bytes.
Organisation of the 2048Byte EEPROMs:
