Command (7)
Command (7)
This command requests transfer of a single sector of data from the host. Table 11-6 defines the content
of this sector of information. If the password does not match the password previously saved by the ATA
Flash Disk Controller, the ATA Flash Disk Controller rejects the command with command aborted. The
Security-Erase-Prepare command should be completed immediately prior to the Security-Erase-Unit
command. If the ATA Flash Disk Controller receives a Security-Erase-Unit command without an
immediately prior Security-Erase-Prepare command, the ATA Flash Disk Controller aborts the Security-
Erase-Unit command.
The Security-Freeze-Lock command sets the ATA Flash Disk Controller to Frozen mode. After
command completion, any other commands that update the ATA Flash Disk Controller Lock mode are
rejected. Frozen mode is disabled by power off or hardware reset. If Security-Freeze-Lock is issued
when the ATA Flash Disk Controller is in Frozen mode, the command executes and the ATA Flash Disk
Controller remains in Frozen mode. After command completion, the sector count register should be set
to 0. Commands disabled by Security-Freeze-Lock are:
- Security-Set-Password
- Security-Unlock
- Security-Disable-Password
- Security-Erase-Unit
If security mode feature set is not supported, this command will be handled as an invalid command.
