16 EEPROM LAYOUT (HANDSET)

16.1. Scope

The purpose of this section is to describe the layout of the EEPROM (IC2) TCD725 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 0F38, and some during normal use of the phone e.g. redial memory at 0311..0392.

16.2. Introduction

The handset uses a 32k bit (4096 x 8) serial EEPROM (IC9) 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.
adjust 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.
