請問各位高手，我的程序：
                          EI
                                               LD   X001
                                               OUT   M8051
                                               LD   M8000
                                               OUT  Y000
                                                DI
                                                 FEND
                                                 I101
                                                 LD   M8013
                                                 OUT   Y001
                                                 IRET
                                                END
                            在我模擬的時候對x001置1以后，y1并沒有輸出呢，這是怎么回事呢，我是個初學者，謝謝大家的不吝賜教。
