+                "0" means device will be reset in case some CS has timed out,

+Description:    Gets the state dump occurring on a CS timeout or failure.
+                State dump is used for debug and is created each time in case of
+                a problem in a CS execution, before reset.
+                Reading from the node returns the newest state dump available.
+                Writing an integer X discards X state dumps, so that the
+                next read would return X+1-st newest state dump.
