The two I C devices on the eZ80
EEPROM and the U13 Configuration register. The EEPROM provides
16KB of memory. The Configuration register provides access to control
the configuration of an application-specific function at the Application
Module Interface. Neither device is utilized by the eZ80F92 Development
Kit software. The user is free to develop proprietary software for these
two devices. The addresses for accessing these devices are listed in
