The contents of this field are right justified and padded with spaces (20H). The right-most ten bytes are
a SST preset, unique ID. The left-most ten bytes are a user-programmable value with a default value of
spaces.
This field defines the buffer capability:
0002H: a dual ported multi-sector buffer capable of simultaneous data transfers to or from the host and
the ATA Flash Disk Controller.
This field defines the buffer capacity in 512 Byte increments. SST’s ATA Flash Disk Controller has up to
2 sector data buffer for host interface.
This field defines the number of ECC bytes used on each sector in the Read- and Write-Long-Sector
commands.
This field contains the revision of the firmware for this product.
This field is reserved for the model number for this product.
This field contains the maximum number of sectors that can be read or written per interrupt using the
Read-Multiple or Write-Multiple commands.
