C141-E203-01EN 5-69

DEVICE CONFIGURATION IDENTIFY (Features Field = C2h)

The DEVICE CONFIGURATION IDENTIFY command returns information
shown in Table 5.23. The content of this data structure indicates the selectable
commands, modes, and feature sets that the device is capable of supporting. If a
DEVICE CONFIGURATION SET command has been issued reducing the
capabilities, the response to an IDENTIFY DEVICE command will reflect the
reduced set of capabilities, however, the DEVICE CONFIGURATION IDENTIFY
command will not be changed.

Error reporting conditions

(1) The device is in the Device Configuration Freeze Lock state

(ST = 51h, ER = 04h).

(2) A SATA communication error occurred (ST = 51h, ER = 14h).

DEVICE CONFIGURATION SET (Features Field = C3h)

The DEVICE CONFIGURATION SET command allows to reduce the set of
optional commands, modes, or feature sets supported by a device as indicated by a
DEVICE CONFIGURATION IDENTIFY command. The format of the overlay
transmitted by the device is described in Table 5.23. As a result to the limitation
of the function by the DEVICE CONFIGURATION SET command, is reflected in
IDENTIFY information. When the bits in these words are cleared, the device no
longer supports the indicated command, mode, or feature set. If a bit is set in the
overlay transmitted by the device that is not set in the overlay received from a
DEVICE CONFIGURATION IDENTIFY command, no action is taken for that bit.
After execution of this command, the settings are kept regardless of the power-on,
COMRESET, or soft reset

If the restriction of Multiword DMA modes or Ultra DMA modes is executed, a
SET FEATURES command should be issued for the modes restriction prior the
DEVICE CONFIGURATION SET command is issued. When the Automatic
