+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
+		ocurred and no transfers have completed since the timeout. A
+		value of 0 indicates that no timeout has ocurred, or if one
+		has, more recent transfers have completed successful.
