Word 66: Device Recommended Multiword DMA Cycle Time
Word 67: Minimum PIO Transfer Cycle Time Without Flow Control
Word 68: Minimum PIO Transfer Cycle Time with IORDY
Word 80: Major Version Number
Word 81: Minor Version Number
This field defines the Device recommended Multiword 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 Device 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. The
Device supports up to Multiword DMA Mode-2, so this field is set to 120ns.
This field defines, in nanoseconds, the minimum cycle time that, if used by the host, the device
guarantees data integrity during the transfer without utilization of IORDY flow control. If this field is
supported, Bit 1 of word 53 shall be set to one. The Device minimum cycle time is 120 ns. A value
of 0078H is reported.
This field defines, in nanoseconds, the minimum cycle time that the device supports while
performing data transfer while utilizing IORDY flow control. If this field is supported, Bit 1 of word 53
shall be set to one. The Device minimum cycle time is 120 ns, e.g., PIO mode 4. A value of 0078H
is reported.
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. The Device supports ATA-1 to ATA-6.
If an implementer 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 shall be 0000H or FFFFH.
A value of 0019H reported in word 81 indicates ATA/ATAPI-6 T13 1410D revision 3a guided the
implementation.
