Marka la falanqeeyo qaabka mowjadda i2c ee addoonka, waxaad sidoo kale heli doontaa dhacdo aad u xiiso badan, markaad akhrinayso xogta diiwaanka, addoonku wuxuu marka hore soo saari doonaa qaabkiisa mawjada ah ee horay loo akhriyay, tusaale ahaan, si uu u akhriyo ciwaanka diiwaangashan ee 0x00, waxaad arki doontaa Qaabka waveform ka dib markii sayidku soo saaro ciwaanka qorista ee 0x00, ka dibna wuxuu soo saari doonaa cinwaanka addoonka si loo akhriyo (R/W = (R/W = 1), addoonku wuxuu soo saari doonaa 8 SCL waveforms si loo akhriyo isla markiiba ka dib qaabka waveform waa la soo saaray, 8-da saacadoodna uma dhigna dhinaca Master-ka sayidku waa la soo saari doonaa mar dambe, markaa addoonku wuxuu u dhigmaa inuu marka hore soo saaro.
Naqshadeynta meeshan waa mid aad u xariif ah sababtoo ah nidaamka i2c wuxuu dhigayaa in fidinta i2c ay ku dhici karto oo kaliya qaybta sagaalaad, taas oo ah, ACK bit.qaabka mawjada looma ogola in la jiido, wax xog ah lagama helin addoonka xilligan, markaa dhibaato ayaa jirta.
Habka TI waa in, mar haddii uu jiro ficil qoraal ah oo ka horreeya, oo ay ku xigto cinwaanka addoonta ah ee la akhriyey isla markiiba ka dib, waxaa cad in ciwaanka diiwaangashan ee la akhrinayo uu yahay midka ku qoran hore, sidaas darteed sayidku wuxuu soo diri doonaa ciwaanka addoonka ah ee akhriya. 9bit ACK jiid marka loo diro sideed SCL si ay u qoraan waxna u akhri, kadibna u sii daayaan SCL, master-ka ayaa ogaanaya sii deynta SCL ka dib Master-ku wuxuu ogaaday in SCL la sii daayo oo dib u soo gudbiyo saacada xogta akhriska, markaas ayaa xogta lagu soo celinayaa PROCESSOR.

LVDS Shuruudaha Guud ama Eray bixinta
1) Lamaane Kala Duwan: Waxa loola jeedaa gudbinta signalka LVDS iyadoo la isticmaalayo laba darawal oo wax soo saar ah si ay u kaxeeyaan laba xariiq oo gudbin ah, midna sido signalka midna sido calaamada kaabaysa.Calaamadda loo baahan yahay waa farqiga u dhexeeya danab ka dhexeeya labada xariiq ee gudbinta, kuwaas oo sidda macluumaadka signalada la kala qaado.
2) Lammaanaha signalka: waxa loola jeedaa wareegga interneedka LVDS halkaas oo wax soo saarka kanaalka gudbinta xogta ama kanaalka gudbinta saacaddu uu yahay laba calaamadood (wax soo saar togan iyo kuwa taban)
3) Isha: Aalad soo saarta ururinta qoraalka, garaafyada, sawirrada, maqalka, iyo xogta muqaalka.
4) Receiver (Sink): waa aaladda socodsiisa soona bandhigta xogta.
5) FPD-LINK: Flat Panel Display Link, muuqaal-xawaaraha sare ee muuqaalka muuqaalka dhijitaalka ah ee ku salaysan heerka LVDS ee uu abuuray Semiconductor National 1996 (oo ay heshay Texas Instruments TI ee 2011) si ay u taageerto wareejinta xogta ee kontoroolka garaafyada ilaa LCD-ga guddi.
6) GMSL: Gigabit Multimedia Serial Link, qaabka borotokoolka gudbinta signalka LVDS ee uu sameeyay Maxim oo ku salaysan heerka LVDS.
7) Kanaalka Horudhaca: Kanaalka gudbinta xogta xawaaraha sare leh ee Serializer ilaa Deserializer.
8) Backchannel: Waxa kale oo loo yaqaan 'Reverse channel', waxa loola jeedaa kanaalka gudbinta xogta xawaaraha yar ee Deserializer ilaa Serializer.
