8.2 Command Descriptions

8.2.1Check Power Mode (E5h)

This command checks the power mode.

If the drive is in, going to, or recovering from the Standby Mode, the drive sets BSY, sets the Sector Count register to 00h, clears BSY, and generates an interrupt.

If the drive is in the Idle Mode, the drive sets BSY, sets the Sector Count register to FFh, clears BSY, and generates an interrupt.

8.2.2Download Micro Code (92h)

This command enables the host to alter the drive’s Micro-code. The data transferred using this command is vendor specific.

8.2.3Device Configuration Overlay (B1h)

The Device Configuration Overlay feature set allows a utility program to modify some of the optional commands, modes, and feature sets that a device reports as supported in the Identify Device command response as well as the capacity reported. Individual Device Configuration Overlay feature set commands are identified by the value placed in the Features register. The following table illustrates these features.

The Device Configuration Restore command disables any setting previously made by a Device.

The Device Configuration Freeze Lock command prevents accidental modification of the Device Configuration Overlay settings. After successful execution of a Device Configuration Freeze Lock Command, all Device Configuration Set, Device Configuration Freeze Lock, Device Configuration Identify command, and Device Configuration Restore commands shall be aborted by the device. The Device Configuration Freeze Lock condition will be cleared only after a power-down.

The Device Configuration Identify command returns a 512 byte data structure via PIO data-in transfer. The content of this data structure indicates the selectable commands, modes, and feature sets that the device is capable of supporting. Should a Device Configuration Set command be issued reducing the capabilities, the response to a Device Configuration Identify command will reflect the reduced set of capabilities accordingly.
