27. EEPROM LAYOUT (BASE UNIT)
27.1. Scope
The purpose of this section is to describe the layout of the EEPROM (IC1) for the KX-TCD410 Base
Unit.
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set
during production of the base e.g. crystal frequency adjustment at address 0000 and 0001, some are
set by the user configuration e.g. ringer volume at address 0220, and some are set during normal use
