With the introduction of this MD it is no longer necessary to define the UMS size in the
configuration file in the MMC master control.
The upper input limit depends on the NCK memory capacity (4 or 8 MB memory).
Zero means no UMS (see functional description of "Flexible memory configuration").

If an area of the memory is reserved for MSD drive software, 194 KB memory is occupied.
Zero means no memory.
The memory is only required for digital drives. The software only loads the MSD software if the
memory has been reserved for it.
