97h
Accepted for backward compatibility . Use of this Feature is not recommended
9Ah
Set the host current source capability. Allows tradeoff between current drawn and
read/write speed.
BBh
4 bytes of data apply on Read/Write Long commands
CCh
Enable Power on Reset (POR) establishment of defaults at Soft Reset
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 D7D0 data bus and the IOIS16 signal will not be
asserted for data register accesses.
Features 0Ah and 8Ah are used to enable and disable Power Level 1 commands. Feature 0Ah is the default
feature for the CompactFlash Storage Card with extended power.
Features 55h and BBh are the default features for the CompactFlash Storage Card; thus, the host does not have to
issue this command with these features unless it is necessary for compatibility reasons. Feature code 9Ah enables
the host to configure the card to best meet the host system’s power requirements. The host sets a value in the
Sector Count register that is equal to one-fourth of the desired maximum average current (in mA) that the card
should consume. For example, if the Sector Count register is set to 6, the card would be configured to provide the
best possible performance without exceeding 24 mA. Upon completion of the command, the card responds to the
host with the range of values supported by the card. The minimum value is set in the Cylinder Low register, and the
maximum value is set in the Cylinder Hi register. The default value, after a power on reset, is to operate at the
highest performance and therefore the highest current mode. The card will accept values outside this
programmable range, but will operate either at the lowest power or highest performance as appropriate.
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.

Set Multiple Mode
This command enables the CompactFlash Storage Card to perform Read and Write Multiple operations and
establishes the block count for these commands. The Sector Count Register is loaded with the number of sectors
per block. Upon receipt of the command, the CompactFlash Storage Card sets BSY to 1 and checks the Sector
Count Register.
If the Sector Count Register contains a valid value and the block count is supported, the value is loaded for all
subsequent Read Multiple and Write Multiple commands and execution of those commands is enabled. If a block
count is not supported, an Aborted Command error is posted, and Read Multiple and Write Multiple commands are
disabled. If the Sector Count Register contains 0 when the command is issued, Read and Write Multiple
commands are disabled. At power on, or after a hardware or (unless disabled by a Set Feature command) software
reset, the default mode is Read and Write Multiple disabled.
Set Sleep Mode – 99h or E6h
