ST72321B DEVICE CONFIGURATION AND ORDERING INFORMATION (Cont’d)
14.2 DEVICE ORDERING INFORMATION AND TRANSFER OF CUSTOMER CODE
Customer code is made up of the ROM/FAS-
TROM contents and the list of the selected options
(if any). The ROM/FASTROM contents are to be
sent on diskette, or by electronic means, with the
S19 hexadecimal file generated by the develop-
ment tool. All unused bytes must be set to FFh.
The selected options are communicated to
STMicroelectronics using the correctly completed
OPTION LIST appended.
