28 EEPROM LAYOUT (CORDLESS HANDSET)
28.1. Scope
The purpose of this section is to describe the layout of the EEPROM (IC10) for the KX-TCA151 Cordless Handset.
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of the
cordless handset e.g. crystal oscillator adjustment at 0057, some are set by the user when configuring the cordless handset e.g.
ringer volume at 00A1, and some during normal use of the phone e.g. redial memory at 1EF6..1F77.
28.2. Introduction
The handset uses a 64k bit serial EEPROM (IC10) for storing volatile parameters. All parameters are set up before the cordless
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
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
x Default - no specific country setting, so revert to default value.
