Ngokuhlaziya i-waveform ye-i2c yesigqila, uzothola into ethakazelisa kakhulu, lapho ufunda idatha yerejista, isigqila sizoqala ngokukhipha i-waveform yayo ukuze ifundwe kusengaphambili, isibonelo, ukufunda ikheli elibhalisiwe 0x00 idatha, uzobona. ku-waveform ngemuva kokuthi inkosi ikhiphe ikheli lerejista yokubhala 0x00, lapho-ke izokhipha ikheli lesigqila ukuze lifundwe (R/W = (R/W = 1), isigqila sizokhipha ama-waveforms angu-8 we-SCL ukuze afundwe kusengaphambili ngokushesha ngemva kokuba i-waveform isiphelile. ekhishiwe, futhi lawawashi ayi-8 awahambisani ohlangothini oluyinhloko oluzokhishwa kamuva, ngakho-ke isigqila silingana nokukhipha kuqala.

Idizayini yale ndawo ihlakaniphe kakhulu ngoba umthetho olandelwayo we-i2c ubeka ukuthi ukwelula kwe-i2c kungenzeka kuphela ngebhithi yesishiyagalolunye, okungukuthi, ibhithi ye-ACK.i-waveform ayivunyelwe ukudonswa, futhi akukho datha etholwa yisigqila kuleli phuzu, ngakho-ke kunenkinga.

Indlela ye-TI iwukuthi, njengoba kunesenzo sokubhala ngaphambili, kulandelwa ikheli lenceku efundwayo ethunyelwe ngokushesha ngemva kwalokho, kuyacaca ukuthi ikheli elibhalisiwe elizofundwa yilona elibhalwe ngaphambili, ngakho-ke inkosi izothumela ikheli lenceku efundwayo. ekudonseni kwe-9bit ACK ngenkathi ithumela ama-SCL ayisishiyagalombili ukuze kubhaliselwe ukufunda nokubhala, bese ikhulula i-SCL, umpetha uthola ukukhululwa kwe-SCL ngemva kokuba Umphathi ethola ukuthi i-SCL ikhululiwe futhi idlulisela kabusha iwashi ledatha elifundiwe, lapho idatha ibuyiselwa khona CPU.

Imigomo Evamile ye-LVDS noma Itemu

I-1) I-Differential Pair: Ibhekisela ekudlulisweni kwesignali ye-LVDS kusetshenziswa abashayeli ababili abakhiphayo ukushayela imigqa yokudlulisela emibili, eyodwa iphethe isignali kanti enye iphethe isignali yayo ehambisanayo.Isignali edingekayo ingumehluko ku-voltage emigqeni emibili yokudlulisela, ethwala ulwazi lwesiginali okufanele ludluliselwe.

2) Ipheya yesignali: ibhekisela kumjikelezo wesixhumi esibonakalayo we-LVDS lapho ukuphuma kwesiteshi ngasinye sokudlulisa idatha noma isiteshi sokudlulisa iwashi kuyizimpawu ezimbili (okuphumayo okuhle nokubi)

3) Umthombo: Idivayisi ekhiqiza iqoqo lombhalo, ihluzo, izithombe, umsindo, nedatha yevidiyo.

4) Isamukeli (Sink): idivayisi ecubungula futhi ibonise idatha.
5) I-FPD-LINK: I-Flat Panel Display Link, ukucaciswa kokusebenzelana kwevidiyo yedijithali enesivinini esikhulu okusekelwe ezingeni le-LVDS elakhiwe yi-National Semiconductor ngo-1996 (etholwe yi-Texas Instruments TI ngo-2011) ukuze kusekelwe ukudluliswa kwedatha kusuka kusilawuli sezithombe kuya ku-LCD. iphaneli.

6) I-GMSL: I-Gigabit Multimedia Serial Link, ifomethi yephrothokholi yokudlulisa isignali ye-LVDS eyakhiwe nguMaxim ngokusekelwe ezingeni le-LVDS.

7) Ishaneli yokuya phambili: Isiteshi esinesivinini esikhulu sokudlulisa idatha kusuka ku-serializer kuya ku-Deserializer.

8) I-Backchannel: Futhi ebizwa ngokuthi i-Reverse channel, ibhekisela esiteshini esinesivinini esiphansi sokudlulisa idatha kusuka ku-Deserializer kuya ku-serializer.
