Word 53: Translation Parameters Valid
Word 54-56: Current Number of Cylinders, Heads, Sectors/Track

Word 60-61: Total Sectors Addressable in LBA Mode
Word 63: Multiword DMA Transfer
Bit
These fields contain the current number of user addressable Cylinders, Heads, and Sectors/Track in
the current translation mode.
This field contains the product of the current cylinders times heads times sectors.
This field contains a validity flag in the Odd Byte and the current numbers of sectors that can be
transferred per 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.
This field contains the number of sectors addressable for the compact flash card in LBA mode only.
This field identifies the Multiword DMA transfer modes supported by the compact flash card module
and indicates the mode that is currently selected. Only one DMA mode shall be selected at any
given time.
