7.3 ORDERING INFORMATION

Each device is available for production in user pro-

grammable version (OTP) as well as in factory

coded version (ROM). OTP devices are shipped to

customer with a default blank content FFh, while

ROM factory coded parts contain the code sent by

customer. There is one common EPROM version

for debugging and prototyping which features the

maximum memory size and peripherals of the sub-

family. Care must be taken to only use resources

available on the target device.

Contact sales office for further ordering informa-

tion and availablity.

7.3.1 Transfer Of Customer Code

Customer code is made up of the ROM contents

and the list of the selected options (if any). 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
