Watch Dog Enable/Disable
JWD1 controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application hangs. The jumper on pins 1-2
(default) causes the Watch Dog to reset the
system if an application hangs. The jumper
on pins 2-3 generates a non-maskable
interrupt signal for the application that
hangs. See the table on the right for jumper
settings. Watch Dog must also be enabled
in BIOS.
Note:
When enabled, the user
must write their own application software
to disable the Watch Dog Timer.
