Watch Dog Enable/Disable
JWD controls the Watch Dog function.
Watch Dog is a system monitor
that can reboot the system when a
software application “hangs”. Pins 1-2
will cause WD to reset the system if
an application hangs. Pins 2-3 will
generate a non-maskable interrupt
signal for the application that has
hung. See the table on the right for
jumper settings. Watch Dog must also
be enabled in BIOS.
Note: When enabled, the user needs
to write their own application software
to disable the Watch Dog Timer.
