7.2.4 Introduction

The following section describes the approved pro-

cedure for transfer of User Program/Data ROM

Code to SGS-THOMSON Microelectronics as well

as the basis for contractual agreement with re-

spect to mask programmed devices.

7.2.5 Communication of the User ROM Code

To formally communicate the desired Program/

Data ROM contents to SGS-THOMSON Microe-

lectronics, the following must be supplied:

– a file in MOTOROLA S19 FORMAT (on diskette,

via electronic mail or by BBS);

– a correctly completed and signed Option List

form as shown overleaf.

The User Code must respect the ROM Memory

Map for the selected device option.

The User Code must be generated using an ap-

proved ST7 assembler. All unused memory loca-

tions shall be set to FFh.

7.2.6 Verification and Formal Approval

When SGS-THOMSON Microelectronics receives

the User Code file, it will return a copy of the proc-

essed file to the Customer. The Customer will then

send formal notification to SGS-THOMSON Mi-

croelectronics, approving the file contents. This

statement and the file copies to which it refers will

then form the basis of the contractual agreement

between the Customer and SGS-THOMSON Mi-

croelectronics and the agreed file will be used to

produce the mask for the programmed MCU de-

vice.

The SGS-THOMSON Sales Organization will be

pleased to provide detailed information relating to
