11.2.1.6.23 Word 66: Device Recommended Multi-word DMA Cycle Time
This field defines the ATA Flash Disk Controller recommended Multi-word DMA transfer cycle time. This
field defines, in nanoseconds, the minimum cycle time per word during a single sector host transfer
while performing a multiple sector READ DMA or WRITE DMA command for any location on the media
under nominal conditions. If a host runs at a faster cycle rate by operating at a cycle time of less than
this value, the ATA Flash Disk Controller may negate DMARQ for flow control. The rate at which
DMARQ is negated could result in reduced throughput despite the faster cycle rate. Transfer at this rate
does not ensure that flow control will not be used, but implies that higher performance may result. SST’s
ATA Flash Disk Controller supports up to Multi-word DMA Mode-2, so this field is set to 120 ns.
11.2.1.6.24 Word 67: Minimum PIO Transfer Cycle Time Without Flow Control
The ATA Flash Disk Controller’s minimum cycle time is 120 ns.
11.2.1.6.25 Word 68: Minimum PIO Transfer Cycle Time With IORDY
The ATA Flash Disk Controller’s minimum cycle time is 120 ns, e.g., PIO Mode-4.
11.2.1.6.26 Word 80: Major Version Number
If not 0000H or FFFFH, the device claims compliance with the major version(s) as indicated by bits (6:1)
being set to one. Since ATA standards maintain downward compatibility, a device may set more than
one bit. SST55LD019x supports ATA-1 to ATA-6.
11.2.1.6.27 Word 81: Minor Version Number
If an implementor claims that the revision of the standard they used to guide their implementation does
not need to be reported or if the implementation was based upon a standard prior to the ATA-3
standard, word 81 should be 0000H or FFFFH.
A value of 0019H reported in word 81 indicates ATA/ATAPI-6 T13 1410D revision 3a guided the
implementation.
