Eeprom Layout (Base Unit) - Panasonic KX-TCD410RUM Service Manual

27 EEPROM LAYOUT (BASE UNIT)

27.1. Scope
The purpose of this section is to describe the layout of the EEPROM (IC1) for the KX-TCD410 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 e.g. meter pulse billing at address 0140..015F.
27.2. Introduction
The base unit uses a 32K 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.
