ESD Precautions

Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:

Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them

Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It discharges
static electricity from your body.

Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

WATCHDOG TIMER

Watchdog Timer Setting

After the system stops working for a while, it can be auto-reset by the
Watchdog Timer. The integrated Watchdog Timer can be set up in the
system reset mode by program.

Sample of Watchdog application

Assume there is program A which needs to maintain running in a
system. The value of Watchdog Timer must be set bigger than the
running time of program A. Then, after the running time of program A is
finished, either to disable or to reset watchdog timer.

When program A has problems to make system shut down, the system
can be rebooted by Watchdog timer when the value of watchdog timer
is countdowned to 0.

The below flowchart can be referred to edit program A.
