ESCRIPTION
SECURITY FREEZE LOCK
F5h
This command is mandatory for devices that implement the Security Mode feature set. The
command shall set the device to Frozen mode. Other commands that update the device Lock
mode are aborted. Frozen mode can be disabled by a power-off or hardware reset. If the
command is issued while the device is in Frozen mode, the command is executed and the device
will remain in Frozen mode.
SECURITY SET PASSWORD
F1h
This command is mandatory for devices that implement the Security Mode feature set. The
command will transfer 512 bytes of predefined data from the host. The data controls the function
of this command, which in turn defines the interaction of the identifier and security level bits. The
user can in turn set the Master or User passwords, and the security level of the device.
SECURITY UNLOCK
F2h
This command is mandatory for devices that implement the Security Mode feature set. The
command will transfer 512 bytes of predefined data from the host. The data controls the function
of this command, which in turn defines the interaction of the Identifier bit. If the Identifier bit is set
to Master and the current security level is high, the password is compared with the stored Master
password. If the device is in maximum security level then the unlock shall be rejected. If the
Identifier bit is set to User, then the device shall compare the supplied password with the stored
User password. If the password comparison fails, the device shall abort the command and report a
decrease in the incremental value in the unlock counter.
SET FEATURES
EFh, xxh
This command is used by the host to establish or select certain features supported by the drive.
When the SSD receives this command, it sets BSY, checks the contents of the Features register,
applies changes as necessary, clears BSY and generates an interrupt. If the value in the register
does not represent a feature supported by the drive, the command is canceled with the Abort Error
condition.
