23. EEPROM LAYOUT (HANDSET)
23.1. Scope
The purpose of this section is to describe “layout of the EEPROM (IC10) KX-TCA155 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 0057, some are set by
the user when configuring the handset e.g. ringer volume at 00A1, and some during normal use
of the phone e.g. redial memory at 1EF6..1F77.
23.2. Introduction
The handset uses a 64k bit serial EEPROM (IC10) 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 addresses in the range.
Initial Type Description
F The data initialized by only F command
0 The data initialized by F and 0 command
1 The data initialized by F, 0 and 1 command
2 The data initialized by all command (F,0,1,2)
Country
Setting
Description
x Default - no specific country setting, so revert to default value.
23.3. EEPROM contents
Note:
In some addresses in the lists below, at the item “Description”, setting time can be changed
depending on Default Value.
When increasing this value, setting time can be either longer or shorter.
