Oku kuquka amaxesha okutyiwa kwesidlo seRx LOS, Tx Fault kunye nezinye iibhithi zeflegi. Rx LOS Assert Ixesha ton_los 100 ms Ixesha ukusuka kwiRx LOS kwimo ukuya kwiRx LOS iseti yesuntswana kunye ne-IntL eqinisekisiweyo yeFlegi ye-Assert Ixesha ton_flag 200 ms Ixesha ukusuka kwisenzeko semeko exhokonxa iflegi ukuya kwiseti yeflegi ehambelanayo kunye ne-IntL yaqinisekisa iMask Assert Ixesha ton_mask 100 ms Ixesha ukusuka kwimaski i-bit set4 ide i-IntL ehambelana nayo ivalwe iMask De-assert Ixesha toff_mask 100 ms Ixesha elisuka kwimaski bit licociwe4 de umsebenzi ohambelana ne-IntlL uqalise kwakhona i-ModSelL Assert Ixesha ton_ModSelL 100 μs Ixesha ukusuka kuqinisekiso lwe-ModSelL ide imodyuli iphendule kugqithiso lwedatha kwi-2-wire serial ibhasi ModSelL Deassert Time toff_ModSel0 Time toff ye I-ModSelL ide imodyuli ingaphenduli kuthumelo lwedatha phezu kwe-2-wire serial bus Power_over-ride orPower-set Assert Time ton_Pdown 100 ms Ixesha ukusuka kwi-P_Down bit set 4 de imodyuli yokusetyenziswa kwamandla ingena kwiNqanaba loMbane eliphantsi Power_over-ride okanye Power-set De -assert Ixesha toff_Pdown 300 ms Ixesha ukusuka kwi-P_Down bit licinyiwe4 de imodyuli isebenze ngokupheleleyo3 Qaphela: 1. Umbane wokuvula uchazwa njengophanyazo xa umbane wonikezelo ufikelela kwaye uhlala ungaphezulu okanye ungaphezulu kwelona xabiso lincinci lichaziweyo. 2. Ukusebenza ngokupheleleyo kuchazwa njenge-IntL eqinisekisiweyo ngenxa yedatha engekakulungeli, bit 0 byte 2 de-asserted. 3. Ilinganiswe ukusuka kumphetho wewotshi ewayo emva kokumiswa kancinci kwentengiselwano yokufunda. 4.
