3.2.1.5.15 Capabilities

Bit 13: Standby Timer

Set to 0, forces sleep mode when host is inactive.

Bit 11: IORDY Support

Set to 0, indicates that this device may support IORDY operation.

Bit 9: LBA support

Set to 1, SST’s CompactFlash supports LBA mode addressing.

Bit 8: DMA Support

This bit is set to 0. DMA mode is not supported.

3.2.1.5.16 PIO Data Transfer Cycle Timing Mode

This field defines the mode for PIO data transfer.

3.2.1.5.17 Translation Parameters Valid

If bit 0 is 1, it indicates that words 54 to 58 are valid and reflect the current number of cylinders, heads

and sectors. If bit 1 is 1, it indicates that words 64 to 70 are valid to support PIO Mode-4.

3.2.1.5.18 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.

3.2.1.5.19 Current Capacity

This field contains the product of the current cylinders times heads times sectors.

3.2.1.5.20 Multiple Sector Setting

This field contains a validity flag in the Odd Byte and the current number of sectors that can be

transferred per interrupt for R/W Multiple in the Even Byte. The Odd Byte is always 01H which indicates

that the Even Byte is always valid.

The Even Byte value depends on the value set by the Set Multiple command. The Even Byte of this

word by default contains a 00H which indicates that R/W Multiple commands are not valid.

3.2.1.5.21 Advanced PIO Data Transfer Mode

CompactFlash supports up to PIO Mode-4.

3.2.1.5.22 Minimum PIO Transfer Cycle Time Without Flow Control

The CompactFlash minimum cycle time is 120 ns.

3.2.1.5.23 Minimum PIO Transfer Cycle Time With IORDY

The CompactFlash minimum cycle time is 120 ns, e.g., PIO Mode-4.

3.2.1.5.24 Total Sectors Addressable in LBA Mode

This field contains the number of sectors addressable for the CompactFlash card in LBA mode only.
