This sequence of event/data flow might happen 1) Initially we have one pending output event 1-1) Then, process the pending output data 2) No pending input event, then we should wait new pending input event 2-1) Wakeup by new pending event (but it's pending output event) In above case, MFT will not report new pending input event if pending output is not processed.
