4.6.2 EEPROM Memory for Setup
The EEPROM is used for setup and configuration data, stored as an alternative to the CMOS-RTC.
Optionally, 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:
Address MAP: Function:
0000h CMOS-Setup valid (01=valid)
0001h Keymatrix-Setup valid (01=valid)
0003h Flag for DLAG-Message (FF=no message)
