    摘要: In a multiple state data signal, a first and second state are equated to logic states while a third state is designated as a read state. The read state and one of the two logic states are alternately generated so that each logic state is immediately preceeded by a read signal which may be utilized to tell the peripheral that a valid bit of data follows.
