Considering the situation;

       tx stream              rx stream
           |                      |
           |                   disable
         enable                   |
           |                    reset

         lock
           |
       tx stream
           |
         enable
           |
        unlock
       --------               ---------
                                lock
                                  |
                              rx stream
                                  |
                               disable
                                  |
                                reset
