MOTOROLA

Ordering Information

149

NOTE:

Begin the application program at the first user ROM location. Program

addresses must correspond exactly to the available on-chip user ROM

addresses as shown in the memory map. Write $00 in all nonuser ROM

locations or leave all nonuser ROM locations blank. Refer to the current

MCU ordering form for additional requirements. Motorola may request

pattern re-submission if nonuser areas contain any nonzero code.

If the memory map has two user ROM areas with the same address,

then write the two areas in separate files on the diskette. Label the

diskette with both file names.

In addition to the object code, a file containing the source code can be

included. Motorola keeps this code confidential and uses it only to

expedite ROM pattern generation in case of any difficulty with the object

code. Label the diskette with the file name of the source code.

19.5 ROM Program Verification

The primary use for the on-chip ROM is to hold the customer’s

application program. The customer develops and debugs the application

program and then submits the MCU order along with the application

program.

Motorola inputs the customer’s application program code into a

computer program that generates a listing verify file. The listing verify file

represents the memory map of the MCU. The listing verify file contains

the user ROM code and may also contain nonuser ROM code, such as

self-check code. Motorola sends the customer a computer printout of the

listing verify file along with a listing verify form.

To aid the customer in checking the listing verify file, Motorola will

program the listing verify file into customer-supplied blank preformatted

Macintosh or DOS disks. All original pattern media are filed for

contractual purposes and are not returned.

Check the listing verify file thoroughly, then complete and sign the listing

verify form and return it to Motorola. The signed listing verify form

constitutes the contractual agreement for the creation of the custom

mask.
