Word 6: Default Number of Sectors per Track
This field contains the number of sectors per track in the default translation mode.
Word 7-8: Number of Sectors
This field contains the number of sectors per NAND Controller. This double word value is also the first
invalid address in LBA translation mode. This field is only required by CF feature set support.
Word 10-19: Serial Number
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.
Word 20: Buffer Type
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 NAND Controller.
Word 23-26: Firmware Revision
This field contains the revision of the firmware for this product.
Word 27-46: Model Number
This field is reserved for the model number for this product.
Word 47: Read-/Write-Multiple Sector Count
This field contains the maximum number of sectors that can be read or written per interrupt using the
Read-Multiple or Write-Multiple commands. Only a value of ‘1’ is supported.
Word 49: Capabilities
Bit
Function
13
Standby Timer
0: forces sleep mode when host is inactive.
11
IORDY Support
1: NAND Controller supports PIO Mode-4.
9
LBA support
1: NAND Controller supports LBA mode addressing.
8
DMA Support
1: DMA mode is supported.
Word 51: PIO Data Transfer Cycle Timing Mode
This field defines the mode for PIO data transfer. NAND Controller supports up to PIO Mode-4.
Word 53: Translation Parameters Valid
Bit
Function
0
1: words 54-58 are valid and reflect the current number of cylinders, heads and sectors.
1
1: words 64-70 are valid to support PIO Mode-3 and 4.
2
1: words 88 are valid to support Ultra DMA data transfer.
Word 54-56: Current Number of Cylinders, Heads, Sectors/Track
These fields contains the current number of user addressable Cylinders, Heads, and Sectors/Track in the
current translation mode.
