Multiword DMA modes 1 and 0. Bit 2, if set to one, indicates that the CompactFlash TM Storage Card supports
Multiword DMA modes 2, 1 and 0.
Support for Multiword DMA modes 3 and above are specific to CompactFlash TM are reported in word 163 as
described in Word 163.
10.8.18 Word 64: Advanced PIO transfer modes supported
This field is bit significant. Any number of bits may be set to ‘1’ in this field by the CompactFlash TM Memory Card to
indicate the advanced PIO modes it is capable of supporting.
3 Bits 7-2 are reserved for future advanced PIO modes.
4 Bit 1 is set to ‘1’, indicates that the CompactFlash TM Memory Card supports PIO mode 4.
5 Bit 0 is set to ‘1’ to indicate that the CompactFlash TM Memory Card supports PIO mode 3.
Support for PIO modes 5 and above are specific to CompactFlash TM are reported in word 163 as described in Word
163.
10.8.19 Word 65: Minimum Multi-Word DMA transfer cycle time
Word 65 of the parameter information of the Identify Device command is defined as the minimum Multiword DMA
transfer cycle time. This field defines, in nanoseconds, the minimum cycle time that, if used by the host, the
CompactFlash TM Storage Card guarantees data integrity during the transfer.
If this field is supported, bit 1 of word 53 shall be set to one. The value in word 65 shall not be less than the
minimum cycle time for the fastest DMA mode supported by the device. This field shall be supported by all
CompactFlash TM Storage Cards supporting DMA modes 1 and above. If bit 1 of word 53 is set to one, but this field is
not supported, the Card shall return a value of zero in this field.
10.8.20 Word 66: Recommended Multi-Word DMA transfer cycle time
Word 66 of the parameter information of the Identify Device command is defined as the recommended Multiword
DMA transfer cycle time. This field defines, in nanoseconds, the cycle time that, if used by the host, may optimize
the data transfer from by reducing the probability that the CompactFlash TM Storage Card will need to negate the
DMARQ signal during the transfer of a sector.
If this field is supported, bit 1 of word 53 shall be set to one. The value in word 66 shall not be less than the value
in word 65. This field shall be supported by all CompactFlash TM Storage Cards supporting DMA modes 1 and above.
If bit 1 of word 53 is set to one, but this field is not supported, the Card shall return a value of zero in this field.
10.8.21 Word 67: Minimum PIO transfer cycle time without flow control
Word 67 of the parameter information of the Identify Device command is defined as the minimum PIO transfer
without flow control cycle time. This field defines, in nanoseconds, the minimum cycle time that, if used by the
host, the CompactFlash TM Storage Card guarantees data integrity during the transfer without utilization of flow
control.
If this field is supported, Bit 1 of word 53 shall be set to one.
Any CompactFlash TM Storage Card that supports PIO mode 3 or above shall support this field, and the value in word
67 shall not be less than the value reported in word 68.
If bit 1 of word 53 is set to one because a CompactFlash TM Storage Card supports a field in words 64-70 other than
this field and the CompactFlash TM Storage Card does not support this field, the CompactFlash TM Storage Card shall
return a value of zero in this field.
10.8.22 Word 68: Minimum PIO transfer cycle time with IORDY
Word 68 of the parameter information of the Identify Device command is defined as the minimum PIO transfer
with IORDY flow control cycle time. This field defines, in nanoseconds, the minimum cycle time that the
CompactFlash TM Storage Card supports while performing data transfers while utilizing IORDY flow control.
If this field is supported, Bit 1 of word 53 shall be set to one.
Any CompactFlash TM Storage Card that supports PIO mode 3 or above shall support this field, and the value in word
68 shall be the fastest defined PIO mode supported by the CompactFlash TM Storage Card.
If bit 1 of word 53 is set to one because a CompactFlash TM Storage Card supports a field in words 64-70 other than
this field and the CompactFlash TM Storage Card does not support this field, the CompactFlash TM Storage Card shall
return a value of zero in this field.
10.8.23 Words 82-84: Features/command sets supported
Words 82, 83, and 84 shall indicate features/command sets supported. The value 0000h or FFFFh was placed in
each of these words by CompactFlash TM Storage Cards prior to ATA-3 and shall be interpreted by the host as
meaning that features/command sets supported are not indicated. Bits 1 through 13 of word 83 and bits 0 through
13 of word 84 are reserved. Bit 14 of word 83 and word 84 shall be set to one and bit 15 of word 83 and word 84
