I n the current version the advanced power management levels are accepted, but don’t influence performance
and power consumption.
Device performance may increase with increasing power management levels. Device power consumption may
increase with increasing power management levels. The power management levels may contain discrete bands.
For example, a device may implement one power management method from 80h to A0h and a higher
performance, higher power consumption method from level A1h to Feh. Advanced power management levels 80h
and higher do not permit the device to spin down to save power.
Feature 85h disables Advanced Power Management. Subcommand 85h may not be implemented on all devices
that implement Set Features subcommand 05h.
Features 0Ah and 8Ah are used to enable and disable Power Level 1 commands. Feature 0Ah is the default feature
for the CF+ CompactFlash Storage Card with extended power as they require Power Level 1 to perform their full set
of functions.
Power Enhanced CF Storage Cards are required to power up and execute all supported commands and protocols in
Power Level 0, their default feature shall be 8Ah: Disable Power Level 1 Commands. No commands are actually
excluded for such cards in Power Level 0 because no commands require Power Level 1. The 8Ah default allows the
cards to restrict their operating power to Power Level 0 limits for compatibility with hosts that do not recognize or
support the extended power capabilities of Power Enhanced CF Storage Cards. It also allows hosts that support
extended power to take advantage of it by setting the feature to 0Ah: Enable Power Level 1 Commands.
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 were 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 shall
accept values outside this programmable range, but shall operate at either 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 shall be set
when a soft reset occurs. The default setting is to revert to the POR defaults when a soft reset occurs.
10.21 Set max address (F9h)
The Set max address command sets the max address of the drive. It is related to the Host protected Area feature
set. Table 82 defines the Set max address command Byte sequence.
