14.1. Scope14.3.1. General Setup14 EEPROM LAYOUT (BASE UNIT)The purpose of this section is to describe the layout of the EEPROM (IC9) for the TCD705 Base Unit.The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of thebase e.g. crystal frequency adjustment at address 0000 and 0001, some are set by the user configuration e.g. ringer volumeat address 0210, and some are set during normal use of the phone e.g. meter pulse billing at address 1040..015F.14.2. IntroductionThe base unit uses a 32k bit (4096 x 8) serial EEPROM (IC9) for storing volatile parameters. All parameters are set up beforethe base leaves the factory. Some of these are vital for the operation of the hardware so a set of default parameters isprogrammed before the actual hardware fine-tuning can be initiated. This document lists all default settings with a shortdescription.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 meansthat the value 00 is repeated in all addresses in the range. All values in this document are in hexadecimal notation.Type Name DescriptionD default The EEPROM location is preset to the Default value by the eeprom default loader.A adjust The EEPROM location is set during the production test and should not be overwritten. The value is set by theeeprom default loader only if the location contains all 1’s (byte: 0xFF, word FFFFh), i, e. it has never been set.- EEPROM location which is not set at all.d default Same as D but best-guess value and/or not verified.14.3.
