Unxibelelwano lwesibuko olunxuseneyo lwendlela yokubhala ixesha luboniswe ngezantsi:
Ixesha lendlela yokufunda unxibelelwano lwezibuko olunxuseneyo libonisiwe kumzobo ongezantsi:
I-CSX yitshiphu yokukhetha umqondiso wokwenza nokukhubaza unxibelelwano lwezibuko olunxuseneyo, i-DCX esebenzayo ephantsi yidatha okanye isignali yokukhetha umyalelo, i-1-bhala idatha okanye imilinganiselo yomyalelo, i-0-bhala umyalelo we-WRX luphawu lolawulo lwedatha lokubhala i-RDX lulawulo lwedatha yokufunda. uphawu Host-D[17:0] yi-bit data port parallel, eneentlobo ezine: 8-bit, 9-bit, 16-bit, kunye 18-bit.
Xa usenza umsebenzi wokubhala, ngesiseko sokuseta kwakhona, qala usete idatha okanye isiginali yokukhetha umyalelo, emva koko tsala itshiphu ukhethe umqondiso ophantsi, emva koko ufake umxholo oza kubhalwa usuka kumamkeli, emva koko utsale uphawu lolawulo lwedatha olusezantsi. . Xa utsalwa phezulu, idatha ibhalwa kwi-IC yokulawula i-LCD kwinqanaba elikhulayo lophawu lokulawula ukubhala. Ekugqibeleni, isignali yokukhetha i-chip itsalwa phezulu kwaye umsebenzi wokubhala idatha ugqityiwe. Xa ufaka umsebenzi wokufunda, ngesiseko sokuseta kwakhona, qala utsale itshiphu ukhethe umqondiso ophantsi, emva koko tsala idatha okanye umyalelo ukhethe umqondiso ophezulu, emva koko utsale umqondiso wolawulo lwedatha ephantsi, emva koko ufunde idatha kwi-LCD yolawulo lwe-IC. . Kwaye ke Umqondiso wokulawulwa kwedatha yokufunda utsalwa phezulu, kwaye idatha ifundwa kumda onyukayo wesiginali yokulawula idatha. Ekugqibeleni, isignali yokukhetha i-chip itsalwa phezulu, kwaye umsebenzi wokufunda idatha ugqityiwe.
