11.2.1.6.17 Word 57-58: Current Capacity
This field contains the product of the current cylinders times heads times sectors.
11.2.1.6.18 Word 59: 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 Read/Write 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 Read/Write Multiple commands are not valid.
11.2.1.6.19 Word 60-61: Total Sectors Addressable in LBA Mode
This field contains the number of sectors addressable for the ATA Flash Disk Controller in LBA mode only.
11.2.1.6.20 Word 63: Multi-word DMA Transfer Mode
This field identifies the multi-word DMA transfer modes supported by the ATA Flash Disk Controller and
indicates the mode that is currently selected. Only one DMA mode can be selected at any given time.

Reserved
10
Multi-word DMA mode 2 selected
1: Multi-word DMA mode 2 is selected and bits 8 and 9 are cleared to 0
0: Multi-word DMA mode 2 is not selected.
9
Multi-word DMA mode 1 selected
1: Multi-word DMA mode 1 is selected and 8 and 10 should be cleared to 0.
0: Multi-word DMA mode 1 is not selected.
8
Multi-word DMA mode 0 selected
1: Multi-word DMA mode 0 is selected and bits 9 and 10 are cleared to 0.
0: Multi-word DMA mode 0 is not selected.
7-3
Reserved
2
Multi-word DMA mode 2 supported
1: Multi-word DMA mode 2 and below are supported and Bits 0 and 1 are set to 1.
1
Multi-word DMA mode 1 supported
1: Multi-word DMA mode 1 and below are supported.
0
Multi-word DMA mode 0 supported
1: Multi-word DMA mode 0 is supported.
11.2.1.6.21 Word 64: Advanced PIO Data Transfer Mode
Bit
Function
0
1: ATA Flash Disk Controller supports PIO Mode-3.
1
1: ATA Flash Disk Controller supports PIO Mode-4.
11.2.1.6.22 Word 65: Minimum Multi-word DMA Transfer Cycle Time Per Word
This field defines the minimum Multi-word DMA transfer cycle time per word. This field defines, in
nanoseconds, the minimum cycle time that the ATA Flash Disk Controller supports when performing
Multi-word DMA transfers on a per word basis. SST’s ATA Flash Disk Controller supports up to Multi-
word DMA Mode-2, so this field is set to 120ns.
