Recalibrate (10h)
The SSD performs only the interface timing and register operations. When this command is issued,
the SSD sets BSY and waits for an appropriate length of time, after which it clears BSY and issues
an interrupt. When this command ends normally, the SSD is initialized.
Security Disable Password (F6h)
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. If the password selected by Word 0 matches
the password that was previously saved by the device, the device shall disable Lock mode. The
command will not change the Master password. The Master password is reactivated when a User
password is set. The command will only complete successfully if the device is in Unlocked mode.
Security Erase Prepare (F3h)
This command is mandatory for devices that implement the Security Mode feature set. The command
is issued immediately before the Security Erase Unit (F4h) command to enable device erasing and
unlocking. The command prevents accidental loss of data on the device.
Security Erase Unit (F4h)
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. If the password does not match the password
previously saved by the device, the device shall reject the command and abort it. When a Normal
Erase mode is specified, the Security Erase Unit command shall write binary zeros to all user data
areas. If the optional Enhanced Erase mode is specified, the device shall write predetermined data
patterns to all user data areas; the current data is overwritten, including sectors that are no longer in
use due to reallocation.
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
