Freescale Semiconductor
On diskettes, the application program must be in Freescale’s S-record format (S1 and S9 records), a
character-based object file format generated by M6805 cross assemblers and linkers.
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
non-user ROM locations or leave all non-user ROM locations blank. Refer to the current MCU ordering
form for additional requirements. Freescale may request pattern re-submission if non-user areas contain
any non-zero code.
If the memory map has two user ROM areas with the same addresses, then write the two areas in
separate files on the diskette. Label the diskette with both filenames.
In addition to the object code, a file containing the source code can be included. Freescale 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 filename of the source code.
15.4 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.
Freescale 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.
Freescale 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, Freescale 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 Freescale. The signed listing verify form constitutes the contractual agreement for the
creation of the custom mask.
15.5 ROM Verification Units (RVUs)
After receiving the signed listing verify form, Freescale 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. Freescale 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 Freescale Quality Assurance.
