g 1. Confirmation

Specify the name of the product being ordered and the type of EPROMs submitted.

Three EPROMs are required for each pattern.

If at least two of the three sets of EPROMs submitted contain identical data, we will produce ROM programming based on

this data. We shall assume the responsibility for errors only if the ROM programming data on the products we produce

differs from this data. Thus, extreme care must be taken to verify the data in the submitted EPROMs.

In the address space of the microcomputer, the internal ROM area is from address 108016 to FFFD16. The reset vector is

stored in addresses FFFC16 and FFFD16.

(1) Set the data in the unused area (the shaded area of the diagram) to “FF16”.

(2) The ASCII codes of the product name “M38749EFT–” must be entered in addresses 000016 to 000916. And set the data

“FF16” in addresses 000A16 to 000F16. The ASCII codes and addresses are listed to the next page.

(3) Addresses 001016 to 001F16 are ASCII codes reserved area of Sub ROM number for the data link layer communication

control circuit. Write ASCII codes of Sub ROM number for the data link layer communication control circuit, which has been

used at developing the submitted ROM, to addresses 001016 to 001F16 of EPROM certainly. Refer to ASCII codes of the

next page at writing.
