        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.
