The Expected Initial Logical Block Reference Tag field contains the value of the Logical Block Reference Tag field
expected in the protection information of the first logical block accessed by the command.
If the ATO bit is set to one in Mode Page 0Ah, the Logical Block Application Tag Mask field contains a value that is a
bit mask for enabling the checking of the Logical Block Application Tag field in the protection information for each
logical block accessed by the command. A Logical Block Application Tag Mask bit set to one enables the checking of
the corresponding bit of the Expected Logical Block Application Tag field with the corresponding bit of the Logical
Block Application Tag field in the protection information.
If the ATO bit is set to zero, the Logical Block Application Tag Mask field and the Expected Logical Block Application
Tag field are ignored.
