♠ Isifunda sesikhathi se-Watchdog
Incazelo Amasekhethi esibali sikhathi se-STWD100 angamadivayisi azimele avimbela ukwehluleka kwesistimu okubangelwa izinhlobo ezithile zamaphutha ezingxenyekazi zekhompuyutha (njengama-peripheral angaphenduli kanye nokubangwa kwebhasi) noma amaphutha esoftware (njengokweqa ikhodi embi kanye nekhodi ibhajwe. ku-loop).
Isibali sikhathi se-STWD100 se-watchdog sinokufaka, i-WDI, nokuphumayo, i-WDO .Okokufaka kusetshenziselwa ukusula isibali sikhathi se-watchdog yangaphakathi ngezikhathi ezithile phakathi nesikhathi sokuvala esishiwo, i-twd.Ngenkathi isistimu isebenza kahle, ngezikhathi ezithile iguqula okokufaka kwe-watchdog, i-WDI.Uma isistimu yehluleka, isibali sikhathi se-watchdog asisethwa kabusha, isexwayiso sesistimu siyakhiqizwa futhi okuphumayo kwe-watchdog, WDO , kuyagonyelwa.
Isekethe ye-STWD100 nayo inephini lokunika amandla, EN , elinganika amandla noma likhubaze ukusebenza kwe-watchdog.Iphinikhodi ye-EN ixhunywe kusici sangaphakathi sokudonsela phansi.Idivayisi inikwe amandla uma iphinikhodi ye-EN ishiywe intanta
