Watch Dog
JWD1 controls the Watch Dog function. The Watch Dog is a monitor that can reboot the
system when a software application hangs. Jumping pins 1-2 will cause the Watch Dog to
reset the system if an application hangs. Jumping pins 2-3 will generate a non-maskable
interrupt signal for the application that hangs. The Watch Dog must also be enabled in the
BIOS. The default setting is Reset.
Note:
When the Watch Dog is enabled, the user needs to write their own application software
to disable it.
