Ho,

I've implemented an eeprom emulation for a LPC2106 in my "T-Clock"-
project. In the application it's just used to store two bytes for
brightness (backlight LED PWM) and contrast (contrast voltage PWM
AD-converter) values of the GLCD. You may find useful information in
the files iap*.* and the linker-scripts in the archive available from 
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/glcd_dcf77
One 8kByte memory-sector is reserved for "persistent storage" but the
emulation is a "512Byte EEPROM" to minimize sector-erase. Basic
approach: IAP and read-modify-write.
