ROMWIDTH

  • Article

This configuration option specifies both the number of data bits of each ROM and how Romimage.exe splits the image. ROM can have 8, 16, or 32 data bits. The size determines the format for the way in which the 32-bit addresses from the OS image are mapped to the data bits.

ROMWIDTH = width

Parameters

  • width
    The width, in bits, of the ROM. The following table shows how Romimage.exe splits the image depending on the value of width.
    Value Description
    32 Romimage.exe puts the entire image into one file.
    16 Romimage.exe splits the image into two files of even and odd 16-bit words.
    8 Romimage.exe splits the image into four files of even and odd 8-bit bytes.

Remarks

This configuration option, along with ROMSIZE and ROMSTART, defines the .abx data format.
