Dear all,
My project use AT89S52.
I want to using WDT but I feel confusse to uses it.
If I reset the WDT a time it mean WDT can't disable again and I must update (reset) the WDT.
In my problem sometime my program is jump not properly after energize the contactor to drive a motor, so if WDT always updated in every program / subrutine I can say this is no meaning uses WDT.
Can anybody give me some trick or program example to using WDT in AT89S52.
thank you varymuch for your attention.

regard
