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 ATA Flash Disk Controller may implement one power
management method from 80H to A0H and a higher performance, higher power consumption method
from level A1H to FEH.
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 ATA Flash Disk Controller with extended power.
Features 55H and BBH are the default features for the ATA Flash Disk Controller; 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 device 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 device should consume. For example, if the Sector
Count register is set to 6, the device would be configured to provide the best possible performance
without exceeding 24 mA. Upon completion of the command, the device responds to the host with the
range of values supported by the device. The minimum value is set in the Cylinder Low register, and the
maximum value is set in the Cylinder High register. The default value, after a power on reset, is to
operate at the highest performance and therefore the highest current mode.
The device 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 software reset occurs.
