HI,

I m trying to implementing WDT in my project.. How to calculate watchdog timer time and what will be the maximum allowable time for WDT before resetting microcontroller??
I have seen an example program in MIKRO C help.. it simply enabled WDT and used the statement "asm CLRWDT" .. i dont understand this.. please explain

Thanks...

If the watchdog timer's counter is initialized to a value that corresponds to five milliseconds of elapsed time, say 10,000, and the software has no bugs, the watchdog timer will never expire; the software will always restart the counter before it reaches zero.
