Each shaded square represents the amount of the DS30 bus, and the offset, which the MBM requires.
***If your system is configured with a 3/5 DS30 bus split, DS30 bus 7 is not available to MBM and DS30 bus 6 is not
supported for the 4x16 and DDIM.
Offset 3 is not currently enabled by the system in BCM 3.6 and later.
