Bit (7:0) is defined as the PIO data and register transfer supported field. If this field is supported, Bit
1of word 53 shall be set to one. This field is bit significant. Any number of bits may be set to one in
this field by the device to indicate the PIO modes the device is capable of supporting. Of these bits,
bit (7:2) are Reserved for future PIO modes.

This field defines the minimum Multiword DMA transfer cycle time per word. This field defines, in
nanoseconds, the minimum cycle time that the compact flash card supports when performing
Multiword DMA transfers on a per word basis. The compact flash card supports up to Multiword
DMA Mode-2, so this field is set to 120ns.
This field defines the compact flash card 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 compact flash card 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 compact flash card 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 compact flash card 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 compact flash card 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 compact flash card 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.
Function
1: PIO Mode-3 is supported.
1: PIO Mode-4 is supported.
