23 EEPROM LAYOUT (BASE UNIT)

23.1. Scope

The purpose of this section is to describe the layout of the EEPROM (IC1) for the KX-TG1105/1106 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 of the phone.

23.2. Introduction

The base unit uses a 32 K bit serial EEPROM (IC1) for storing volatile parameters. All parameters are set up before the base
leaves the factory. Some of these are vital for the operation of the hardware so a set of default parameters is programmed
before the actual hardware fine-tuning can be initiated. This document lists all default settings with a short description.
In the tables below values in a range that are similar are not repeated; i.e. Address 00 to 01 contains the value 00 simply means
that the value 00 is repeated in all addresses in the range. All values in this document are in hexadecimal notation.

The EEPROM location is preset to the Default value by the eeprom default loader.
The EEPROM location is set during the production test and should not be overwritten. The value is set by the
eeprom default loader only if the location contains all 1's (byte: 0xFF, word FFFFh), i, e. it has never been set.
EEPROM location which is not set at all.
Default - no specific country setting, so revert to default value
