740 FAMILY MASK ROM CONFIRMATION FORM

SINGLE-CHIP MICROCOMPUTER M37640M8-XXXFP

MITSUBISHI ELECTRIC

We recommend the use of the following pseudo-command to set the start address of the assembler source program

because ASCII codes of the product name are written to addresses 000016 to 000816 of EPROM.

EPROM type

The pseudo-command

27512

*= $0000

.BYTE ‘M37640M8-’

Note : If the name of the product written to the EPROMs does not match the name of the mask confirmation

form, the ROM will not be processed.

Ordering by floppy disk

We will produce masks based on the mask file generating utility. We shall assume the responsibility for errors

only if the mask ROM data on the products differs from this mask file. Therefore, extreme care must be taken to

verify the accuracy of the mask file submitted.

The floppy disk must be 3.5-inch 2HD type and DOS/V format. Only one mask file per floppy disk should be

submitted.

File Code

(hexadecimal notation)

Mask file name

.MSK (equal or less than eight characters)

* 1. Mark specification

Mark specification must be submitted using the correct form for the package being ordered. Fill out

the appropriate mark specification form 80P6N and attach it to the mask ROM confirmation form.

* 2. Usage conditions

Please answer the following questions about usade for use in our product inspection.

(1) How will you use the Xin-Xout oscillator?

Quartz crystal

Other (

)

External clock input

At what frequency?

f(Xin) =

MHz

(2) Which function will you use the pins P50/XCin and P51/XCout as P50 and P51, or XCin and XCout ?
