3.2.1.17 Set Features - EFH
This command is used by the host to establish or select certain features. Table 3-10 defines all features
that are supported.
Features 01H and 81H are used to enable and clear 8-bit data transfer modes in True IDE 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.
Features 55H and BBH are the default features for the CompactFlash card; thus, the host does not
have to issue this command with these features unless it is necessary for compatibility reasons.
Features 66H and CCH can be used to enable and disable whether the Power On Reset (POR)
Defaults will be set when a soft reset occurs. The default setting is to revert to the POR defaults when a
soft reset occurs.
