Pseudo-status signal generator. |
摘要 |
<p>A pseudo-status signal generator (4) is interposed between a main device (lA), in which a ready state is always maintained, and an input/output requesting device (2) adapted to produce a predetermined input/output request to the main device. The pseudo-signal generator (4) is arranged to alternatively repetitively produce a status signal representing a ready state and a status signal representing a busy state to the input/output requesting device (2) whenever a status request is output from the input/output requesting device; i.e., repeating the busy or ready for the status request of this time when the ready or busy is repeated to the previous status.</p> |
