Word 59: Multiple Sector Setting
● Bits 15-9 are reserved and must be set to ‘0’.
● Bit 8 is set to ‘1’, to indicate that the Multiple Sector Setting is valid.
● Bits 7-0 are the current setting for the number of sectors to be transferred for every

10.4.17 Word 63: Multi-Word DMA transfer
Bits 15 through 8 of Word 63 of the Identify Device parameter information identifies which
Multi-Word DMA mode that has been selected by host.Each bit of Word 0 is significant. Only
one of these bits can be set to ‘1’ by the CompactFlash Storage Card to indicate the Multi-
Word DMA mode which is currently selected:
● Bits 15 to 11 are reserved.
● Bit 10: when set to ‘1’, it indicates that Multi-Word DMA mode 1 has been selected.
● Bit 9: when set to ‘1’, it indicates that Multi-Word DMA mode 1 has been selected.
● Bit 8: when set to ‘1’, it indicates that Multi-Word DMA mode 0 has been selected.
Bits 7 to 0 define the Multi-Word DMA data transfer supported field. Any number of bits may
be set to one in this field by the CompactFlash Storage Card to indicate which Multi-Word
DMA mode is supported:
● Bit 7 to 3 are reserved.
● Bit 2: when set to ‘1’, it indicates that the CompactFlash Storage Card supports Multi-
Word DMA modes 2, 1 and 0.
● Bit 1: when set to ‘1’, it indicates that the CompactFlash Storage Card supports Multi-
Word DMA modes 1 and 0.
● Bit 0: when set to ‘1’, it indicates that the CompactFlash Storage Card supports Multi-
Word DMA mode 0.
Note: 1 Selection of Multi-Word DMA modes 3 and above are specific to CompactFlash, and are
reported in Word 163.
2 Support for Multi-Word DMA modes 3 and above are specific to CompactFlash are reported
