+Description:
+		Sends an FSI terminate command from the master to its
+		connected slave. A terminate resets the slave's state machines
+		that control access to the internally connected engines.  In
+		addition the slave freezes its internal error register for
+		debugging purposes.  This command is also needed to abort any
+		ongoing operation in case of an expired 'Master Time Out'
+		timer.

+Description:
+		Indicates whether or not this SBE device has experienced a
+		timeout; i.e. the SBE did not respond within the time allotted
+		by the driver. A value of 1 indicates that a timeout has
+		occurred and no transfers have completed since the timeout. A
+		value of 0 indicates that no timeout has occurred, or if one
+		has, more recent transfers have completed successfully.
