WAFER-5820 is designed for limited space applications with
only the size of a 3½" hard drive. It supports the full functions of an
AT & ATX-compatible industrial computer on a single board. The
WAFER-5820 is equipped with a low-power consumption and high
performance GX1-300 processor on board. It also contains an
SDRAM SODIMM socket that can support up to 512MB memory.
The WAFER-5820 provides an Ethernet interface, audio
interface, socket for DiskOnChip, EIDE interface, one parallel port,
one serial ports RS-232, one series ports RS-232/422/485 with
self-tuner, and a mini-DIN PS/2 keyboard/mouse interface. The
built-in SVGA/LCD display controller supports both the CRT and
LCD display simultaneously. It offers the resolutions of LCD
screen up to 1024 x 768 and CRT resolutions up to 1280 x 1024
@ 16 colors. It also provides LVDS interface for long distance LCD
panel signal transmission. The display type is configured by
software utility. The Flash ROM contains both the system BIOS
and the VGA BIOS. The modification, in case of necessary, could
be done by reprogramming the Flash ROM.
The RS485 has an outstanding characteristic of intelligent
directing control which eliminates the extra control signal like RTS.
With this feature you can develop your program as you are using a
normal RS232 without special control routine. This is especially
important in WINDOWS programming which do not allow the
program to catch the control pin at your wish.
Finally, one PC/104 connector is included for the future
application you will need.

5.1 Introduction
The WAFER-5820 is equipped with on-board LCD/VGA
interface. The description below is its specifications and features:
5.1.1 Chipset
The WAFER-5820 uses a Cyrix CX5530 chipset as its
SVGA controller. It is compatible with many common 18-bit
LCD displays and traditional analog CRT monitors. The VGA
BIOS supports LCD. Besides, it also accepts interlaced and
non-interlaced analog monitors (color and monochrome
VGA) with high-resolution quality while maintaining complete
IBM VGA compatibility. But digital monitors (i.e. MDA, CGA,
and EGA) can be NOT supported. Multiple frequency
(multisync) monitors are operated as if they were analog
monitors.
5.1.2 Display memory
Having 1.5 ~ 4 MB UMA memory, the VGA controller can
make CRT displays or color panel displays perform with
resolutions up to 1024 x 768 at 64 K colors. The display

PCI Bus Ethernet Interface
7.1 Introduction
The WAFER-5820 provides a high performance 32-bit Ethernet
chipset which is completely compliant with IEEE 802.3 100 Mbps
CSMA/CD standards. It is both 100Base-T and 10Base-T
compatible. The major network operating system fits it. The
medium type can be set up via the RSET8139.exe program
included on the utility CD.
The Ethernet port supplies a standard RJ-45 connector on
board. To utilize the network boot feature is by incorporating the
boot ROM image files for the appropriate network operating
system. The boot ROM BIOS files are combined with system BIOS,
which can be enabled/disabled in the BIOS setup.
Appendix A. Watch-Dog Timer
The WatchDog Timer is a device to ensure that standalone
systems can always recover from catastrophic 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 Watch-Dog Time period
443 (hex) Read Enable the refresh the Watch-Dog Timer.
043/843
(hex)
Prior to enable the Watch-Dog 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.
Read Disable the Watch-Dog Timer.

41
This will enable and activate the countdown 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
42
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
Watch-Dog Timer, otherwise the system will reset.
Example assembly program:
TIMER_PORT = 443H
TIMER_START = 443H
TIMER_STOP = 843H
