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

STMicroelectronics using the correctly completed

OPTION LIST appended.

Refer to application note AN1635 for information

on the counter listing returned by ST after code

has been transferred. The STMicroelectronics

Sales Organization will be pleased to provide de-

tailed information on contractual points.

Caution: The Readout Protection binary value is

inverted between ROM and FLASH products. The

option byte checksum will differ between ROM and

FLASH.
