WORD 66: Manufacturer recommended multiword DMA transfer cycle time
If the data transfer is requested in a shorter cycle time than this definition, the data transfer may be kept
pending with DMARQ low because data is not ready. The value for this WORD is 0078h (120ns).
WORD 67: Minimum PIO transfer cycle time without flow control (ns)
The Drive can guarantee correct data transfer without flow control in this cycle time or longer. If this bit is
supported, word 53 bit 1 is to be set. The drives which support PIO mode 3 or higher shall support this field
too. This figure shall not be less than 120. The value for this WORD is 0078h (120ns).
WORD 68: Minimum PIO transfer cycle time with IORDY flow control (ns)
If this bit is supported, word 53 bit 1 is to be set. The drive that support PIO mode 3 or higher shall support
this field too. This figure shall not be less than 120. The value for this WORD is 0078h (120ns).
WORD 69-79: Reserved
WORD 80: Major version number
If not 0000h or FFFFh, the device claims compliance with the major version(s) as indicated by bits 1 - 6
being equal to one. Values other than 0000h and FFFFh are bit significant. Since the ATA standards
maintain downward compatibility, a device may set more than one bit .
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 this revision of the
standard, Word 81 shall be 0000h or FFFFh.
WORD 82: Command sets supported
bit 15 Reserved
bit 14 NOP command supported
bit 13 READ BUFFER command supported
bit 12 WRITE BUFFER command supported
bit 11 Reserved
bit 10 Host Protected Area feature set supported
bit 9 DEVICE RESET command supported
bit 8 SERVICE interrupt supported
bit 7 Release Interrupt supported
bit 6 Look Ahead supported
bit 5 Write Cache supported
bit 4 PACKET feature set supported
bit 3 The Power Management feature set is supported
bit 2 The Removable feature set is supported
bit 1 The security feature set is supported
bit 0 The SMART feature set is supported
The value for this WORD is 746Bh.
