2.2 Unpacking Precautions
Some components of WAFER-5822 SBC are very
sensitive to static electric charges and can be
damaged by a sudden rush of power. To protect it from
unintended damage, be sure to note these
precautions:
Ground yourself to remove any static charge before
touching the Wafer-5822 SBC. 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 Wafer-5822 SBC by its edges. Don’t
touch IC chips, leads or circuitry if not necessary.
Do not plug any connector or jumper while the power is
on.
2.3 System Memory DRAM
There is one 144-pin SO-DIMM socket to accept 3.3V
non-buffered SDRAM. The max. Memory size is
128MB.
2.4 Watchdog Timer Setting
Reading 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 to start again, or
activate NMI to CPU. Reading port 043/843H disables
the Watchdog Timer. Refer to Appendix A for detail
information

3.16 Digital I/O (CN10)
One characteristic of digital circuit is its fast
response to high or low signal. This kind of
response is highly needed for harsh and critical
27
industrial operating environment. That’s why we
design 4-bit digital inputs and 4-bit digital outputs on
the WAFER -5822.
Digital Input and Output, generally, are control
signals. You can use these signals to control

Appendix A. Watchdog Timer
The Watchdog Timer is a device to ensure that
standalone systems can always recover from catastrop hic
conditions that cause the CPU to crash. This condition
may have occurred by external EMI or a software bug.
When the CPU stops working normally, hardware on the
board will perform hardware reset (cold boot) to bring the
system back to a known state.
Three I/O ports control the Watchdog Timer.
443 Write Set Watchdog Time period
443

Read Enable the refresh the Watchdog Timer.
043/843

Read Disable the Watchdog Timer.
Prior to enable the Watchdog Timer, user has to define
Timer first. The output data is a value of time interval and
the range of the value is from 01(hex) to FF (hex) and time
interval 1 sec to 255 sec.

This will enable and activate the countd own timer which
will eventually time out and reset the CPU to ensure that
this reset condition does not occur, the Watch-Dog Timer
must be periodically refreshed by reading the same I/O
port 043/843H and 443H. This must be done within the
time out period that is selected by software, please refer to
the example program.
A tolerance of at least 5% must be maintained to avoid
unknown routines within the operating system (DOS), such
as disk I/O that can be very time consuming. Therefore if
the time-out period has been set to 10 seconds, the I/O
port 443H must be read within 7 seconds.
Note: when exiting a program it is necessary to disable the
Watchdog Timer, otherwise the system will reset.
Example assembly program:
TIMER_PORT = 443H
TIMER_START = 443H
TIMER _STOP = 843H
