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

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.
