28 EEPROM LAYOUT (HANDSET)

28.1. Scope

The purpose of this section is to describe "the layout of the EEPROM (IC2) for the KX-A144 Handset".
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of the
handset e.g. crystal oscillator adjustment at 0000..01, some are set by the user when configuring the handset e.g. ringer volume
at 0F3E, and some during normal use of the phone.

28.2. Introduction

The handset uses a 32k bit serial EEPROM (IC2) for storing volatile parameters. All parameters are set up before the handset
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.
This document lists all default parameters 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 addressee in the range.

Description
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 0xFF, 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
