Product Manual
interrupt for R/W Multiple in the even byte. The odd byte is always 01H, which
indicates that the even byte is always valid.
The even byte value depends on the value set by the Set Multiple command.
The even byte of this word by default contains a 00H, which indicates that
R/W Multiple commands are not valid. The only other value returned by the
CompactFlash Memory Card in the even byte is a 01H value, which indicates
that 1 sector per interrupt, can be transferred in R/W Multiple mode.
Words 60-61: Total Sectors Addressable in LBA Mode. This field contains
the number of sectors addressable for the CompactFlash Card in LBA mode
only.
Word 64: Advanced PIO Transfer Modes Supported. Bits 0 and 1 of this
field are set to indicate support for PIO transfer modes 3 and 4, respectively.
Word 65: Minimum Multiword DMA Transfer Cycle Time per Word.
Word 65 of the parameter information of the IDENTIFY DEVICE command is
defined as the Minimum Multiword DMA Transfer Cycle Time per Word. This
field defines the minimum cycle time, in nanoseconds, that the device can
support when performing Multiword DMA transfers on a per word basis.
Word 66: Recommended Multiword DMA 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 the
minimum cycle time, in nanoseconds, per word during a single sector host
transfer while performing a multiple sector READ DMA or WRITE DMA
commands over all locations on the media under minimal 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 cycled rate.
Transfer at this rate does not ensure that flow control will not be used, but
implies that higher performance may result.
Word 67:
Minimum PIO Transfer Cycle Time Without Flow Control.
This field indicates the minimum cycle time, in nanoseconds, that, if used by
the host, the card guarantees data integrity during the cycle without utilization
of flow control.
Word 68: Minimum PIO Transfer Cycle Time With Flow Control. This
field indicates the minimum cycle time, in nanoseconds, that the card supports
while performing data transfers using flow control.
Words 82-84: Features/Command Sets Supported. Words 82, 83, and 84
indicate the features and command sets supported. The value 0000h or FFFFh
was placed in each of these words by CompactFlash cards prior to ATA-3 and
will 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 will be set to "1,"
and bit 15 of Word 83 and Word 84 will be cleared to zero which indicates that
the features and command sets supported words are valid. Host implementers
should not depend upon the values in these words.
