EAERP (Error AER Permission) bit (obsolete)
1 An Error AER Permission (EAERP) bit of one specifies that the target may issue an asynchronous event report upon detecting a deferred
error condition instead of waiting to report the deferred error on the next command.
0 An EAERP bit of zero specifies that the target shall not report deferred error conditions via an asynchronous event reporting.
ATO (application tag owner) bit
1 An application tag owner (ATO) bit set to one specifies that the contents of the LOGICAL BLOCK APPLICATION TAG field in the protection
information, if any, shall not be modified by the device server.
0 An ATO bit set to zero specifies that the contents of the LOGICAL BLOCK APPLICATION TAG field in the protection information, if any, may
be modified by the device server. If the ATO bit is set to zero, the device server shall ignore the contents of the LOGICAL BLOCK APPLICA-
TION TAG field in the protection information when received from the application client.
TAS (Task Aborted Status) bit
0 A task aborted status (TAS) bit set to zero specifies that aborted tasks shall be terminated by the device server without any response to
the application client.
1 A TAS bit set to one specifies that tasks aborted by the actions of an I_T nexus other than the I_T nexus on which the command was
received shall be terminated with a TASK ABORTED status (see SAM-5).
ATMPE bit
0 An application tag mode page enabled (ATMPE) bit set to zero specifies that the Application Tag mode page (see 5.3.6) is disabled and
the contents of logical block application tags are not defined by this standard.
1 An ATMPE bit set to one specifies that the Application Tag mode page is enabled.
If:
a) the ATMPE is set to one;
b) the ATO bit is set to one;
c) the value in the DPICZ bit allows protection information checking for the specified command; and
d) the APP_CHK bit is set to one in the Extended INQUIRY VPD page (see 5.4.9);
then:
knowledge of the value of the Application Tag shall come from the values in the Application Tag mode page as specified by the DPICZ
bit.
