File
The controller has a Memory Module Information (MMI) File which is
updated with data from the attached memory module. At power-up or on
detection of a memory module being inserted, the catalog number, series,

program. If a memory module is not attached, zeros are written to the
MMI file.

The parameters and their valid ranges are shown in the table below.
