This configuration option specifies

  • The number of data bits of each ROM
  • How Romimage.exe splits the run-time 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 run-time image are mapped to the data bits.

    The width, in bits, of the ROM.

    The following table shows how Romimage.exe splits the run-time image depending on the value of width.
