ATA Command Description
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.
5.1.5.23. 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.
5.1.5.24. 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.
5.1.5.25. Word 67: Minimum PIO Transfer Cycle Time Without Flow Control
This field indicates in nanoseconds, the minimum cycle time that, if used by the host, the CompactFlash Card
guarantees data integrity during the cycle without utilization of flow control.
5.1.5.26. Word 68: Minimum PIO Transfer Cycle Time With Flow Control
This field indicates in nanoseconds, the minimum cycle time the CompactFlash Memory Card supports while
performing data transfers using flow control.
5.1.5.27. 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. The values in these words
should not be depended on by host implementers.
