The following section deals with the procedure for
transfer of customer codes to STMicroelectronics.
8.3.2 Transfer of Customer Code
Customer code is made up of the ROM contents
and the list of the selected mask options. The
ROM contents are to be sent on diskette, or by
electronic means, with the hexadecimal file gener-
ated by the development tool. All unused bytes
must be set to FFh.
The selected mask options are communicated to
STMicroelectronics using the correctly filled OP-
TION LIST appended. See

8.3.3 Listing Generation and Verification
When STMicroelectronics receives the user’s
ROM contents, a computer listing is generated
from it. This listing refers exactly to the mask which
will be used to produce the specified MCU. The
listing is then returned to the customer who must
thoroughly check, complete, sign and return it to
STMicroelectronics. The signed listing forms a
part of the contractual agreement for the creation
of the specific customer mask.
The STMicroelectronics Sales Organization will be
pleased to provide detailed information on con-
tractual points.
