Hello, Can a watchdog timer of AT89s8252 reset the CPU in case of program crash ??? .I couldnt find this info PLEASE HELP !! . Kind Regards JG
I think you are confusing a "supervisor", which monitors things like supply voltage, with a Watchdot Timer (WDT). A WDT is simply a timer which will reset the CPU if you allow it to time-out. Of course, some devices implement both a "supervisor" and a WDT (and also a Reset generator) into a single device - but the functions are distinct. I'm afraid I don't know the detail of the AT89s8252 - but I'm sure you can read the datasheet as well as I could!
