JBT1 & JCMOS
JBT1 is used to clear the saved system setup configuration stored in the
CMOS chip. To clear the contents of the CMOS usng JBT1, short the two
pads of JBT1 with a metallic conductor such as a flathead screwdriver.
JCMOS works similarly to JBT1. Close pins 2 and 3 of JCMOS to clear
CMOS. This will erase all user settings and revert everything to their
factory defaults.

Watch Dog (JWD1) is a system monitor
that can reboot the system when a soft-
ware application hangs. Close pins 1 and
2 to reset the system if an application
hangs. Close pins 2 and 3 to generate a
non-maskable interrupt signal for the ap-
plication that hangs. Refer to the table on
the right for jumper settings.
