JWD enables the Watch Dog function,
a system monitor that takes action
when a software application freezes
the system. Jumping pins 1-2 will
have WD reboot the system if a pro-
gram freezes. Jumping pins 2-3 will
generate a non-maskable interrupt for
the program that has frozen. See the
table on the right for jumper settings.
Watch Dog must also be enabled in

write their own application software to disable the
Watch Dog Timer.
