1.2 ORDERING INFORMATION

The following section deals with the procedure for

transfer of customer codes to SGS-THOMSON.

1.2.1 Transfer of Customer Code

Customer code is made up of the ROM contents

and the list of the selected FASTROM options.

The ROM contents are to be sent on diskette, or

by electronic means, with the hexadecimal file

generated by the development tool. All unused

bytes must be set to FFh.

The selected options are communicated to SGS-

THOMSON using the correctly filled OPTION

LIST appended.

1.2.2 Listing Generation and Verification

When SGS-THOMSON receives the user’s ROM

contents, a computer listing is generated from it.

This listing refers exactly to the ROM contents and

options which will be used to produce the speci-

fied MCU. The listing is then returned to the cus-

tomer who must thoroughly check, complete, sign

and return it to SGS-THOMSON. The signed list-

ing forms a part of the contractual agreement for

the production of the specific customer MCU.

The SGS-THOMSON Sales Organization will be

pleased to provide detailed information on con-

tractual points.
