Freescale Semiconductor, Inc.
GENERAL RELEASE SPECIFICATION
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.
14.3 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 non-user 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 the listing verify form to Motorola. The signed listing verify form
constitutes the contractual agreement for the creation of the custom mask.
14.4 ROM Verification Units (RVUs)
After receiving the signed listing verify form, Motorola manufactures a custom
photographic mask. The mask contains the customer’s application program and is
used to process silicon wafers. The application program cannot be changed after
the manufacture of the mask begins. Motorola then produces 10 MCUs, called
RVUs, and sends the RVUs to the customer. RVUs are usually packaged in
unmarked ceramic and tested to 5 Vdc at room temperature. RVUs are not tested
to environmental extremes because their sole purpose is to demonstrate that the
customer’s user ROM pattern was properly implemented. The 10 RVUs are free
of charge with the minimum order quantity. These units are not to be used for
qualification or production. RVUs are not guaranteed by Motorola Quality
Assurance.
