♠ Watchdog timer circuit
Kev piav qhia Lub STWD100 watchdog timer circuits yog cov khoom siv rau tus kheej uas tiv thaiv kev ua haujlwm tsis ua haujlwm uas yog tshwm sim los ntawm qee hom kev kho vajtse yuam kev (xws li, tsis teb cov khoom siv hluav taws xob thiab kev sib cav tsheb npav) lossis software yuam kev (xws li tus lej tsis zoo dhia thiab tus lej daig hauv lub voj voog).
Lub STWD100 watchdog timer muaj cov tswv yim, WDI, thiab cov zis, WDO .Cov tswv yim yog siv los tshem tawm lub sijhawm saib xyuas sab hauv ib ntus hauv lub sijhawm teem sijhawm, twd.Thaum lub kaw lus ua haujlwm kom raug, nws ib ntus toggles tus saib xyuas cov tswv yim, WDI.Yog tias lub kaw lus tsis ua haujlwm, lub sijhawm saib xyuas lub sijhawm tsis rov pib dua, lub kaw lus ceeb toom raug tsim tawm thiab cov khoom siv saib xyuas, WDO, tau lees paub.
Lub STWD100 Circuit Court kuj tseem muaj tus pin pab, EN, uas tuaj yeem pab lossis cuam tshuam cov haujlwm saib xyuas.Lub EN tus pin txuas nrog lub zog rub-down resistor.Cov cuab yeej siv tau yog tias EN tus pin sab laug ntab
