U2 EEPROM and the U13 Configuration register. The EEPROM pro-
vides 16 KB of memory. The Configuration register provides access to
control the configuration of an application-specific function at the Appli-
cation Module Interface. Neither device is utilized by the eZ80F92 Devel-
opment Kit software. The user is free to develop proprietary software for
these two devices. The addresses for accessing these devices are listed in
