Onyx-MM-DIO-l on 48 digitaalset sisend-v\u00e4ljundliini, mis kasutavad kahte 82C55 integraall\u00fclitust.

Re\u017eiimis 0 teostatakse p\u00f5hilisi sisend- ja v\u00e4ljundoperatsioone. K\u00e4epigistussignaale ei kasutata. See on k\u00f5ige levinum digitaalse sisendi ja v\u00e4ljundi meetod ning sobib h\u00e4sti olekusignaalide lugemiseks, l\u00fclitite sisse- ja v\u00e4ljal\u00fclitamiseks jne. K\u00f5ik kolm porti v\u00f5ivad t\u00f6\u00f6tada re\u017eiimis 0. <\/p>\n

1. re\u017eiimis toimub portides A ja B strobitud sisend-v\u00e4ljund, kusjuures portis C edastatakse k\u00e4epigistussignaale. Sisendre\u017eiimis on \u00fcks signaal strob, mis lukustab andmed porti, ja teine signaal on kinnitussignaal. V\u00e4ljundre\u017eiimis kasutatakse \u00fchte signaali selleks, et n\u00e4idata, et CPU on porti uued andmed kirjutanud, ning teine signaal on kinnitussisend. <\/p>\n

2. re\u017eiimis on v\u00f5imalik kasutada porti A kahesuunalise andmesideliinina, kusjuures porti C liine kasutatakse k\u00e4epigistamiseks. Port A on tavaliselt kolmeolekure\u017eiimis. Kui CPU kirjutab uued andmed porti A, n\u00e4itab v\u00e4ljundsignaal, et uued andmed on saadaval. Selle peale saadab v\u00e4lisringkond kinnitussignaali, aktiveerides seel\u00e4bi porti A v\u00e4ljundpuhvrid. V\u00e4lisringkond v\u00f5ib ka sisendandmete strobe-signaaliga uued andmed porti A salvestada. <\/p>\n
