Ground yourself to remove any static charge before touching
the ETX-DB-ATX. You can do it by using a grounded wrist
strap at all times or by frequently touching any conducting
materials that is connected to the ground.
Handle your ETX-DB-ATX by its edges. Don’t touch IC chips,
leads or circuitry if not necessary.

2.5 WatchDog Timeout Active Selector
Connection
Reading I/O port 443H enables the WatchDog Timer. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a
reset signal or an interrupt signal. The Watch-Dog Timer is
disabled by reading port 043/843H.detail information on
WatchDog Timer Refer to Appendix A
This chapter describes how to connect peripherals, switches
and indicators to the ETX-DB-ATX board.
