    hi,
    with 89S52, is there any possibility to know whether the reset is happened with power on or watchdog timer. Can we check it at the starting at the problem.
    please give the information regarding this.
    Rgds,
    Shabbir.

    I am not aware of any register(bit) that indicates WD reset. However, because a WD will drive the reset pin, you could latch that conditon for inspection.
