ATA Command Description
5.1.17. Set Features—EFH
This command is used by the host to establish or select certain features. Table 5- defines all features that are
supported. Please note that the 9AH feature is unique to the CompactFlash Memory Card and are not part of the
ATA Specification.
Features 01H and 81H are used to enable and clear 8 bit data transfer mode. If the 01H feature command is issued,
all data transfers will occur on the low order D7-D0 data bus and the IOIS16 signal will not be asserted for data
register accesses.
A host can choose the transfer mechanism by Set Transfer Mode and specifying a value in the Sector Count register.
The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value.
Where “nnn” is a valid mode number in binary, “x” is the mode number in decimal for the associated transfer type,
and “d” is ignored.
Features 55H and BBH are the default features for the CompactFlash Memory Card; thus, the host does not have to
issue this command with these features unless it is necessary for compatibility reasons.
