See WRITE AND VERIFY (10) - (2E) for descriptions of the WRPROTECT, DPO, ByteChk, Logical Block Address, and
Transfer Length fields.
When checking of the Logical Block Reference Tag field is enabled, the Expected Initial Logical Block Reference T a g fi eld
contains the value of the Logical Block Reference Tag field expected in the protection information of the first logical block
accessed by the command, instead of a value based on the LBA.
If the ATO bit is set to one in Mode Page 0A and checking of the Logical Block Application Tag field is enabled, the Logical
Block Application Tag Mask field contains a value that is a bit mask for enabling the checking of the Logical Block Applica-
tion 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 one in Mode Page 0A and the checking of the Logical Block Application Tag field is disabled, or 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.
