system. Removing the jump from JP6 to open and start the system.
3.5
WDT Function
The working algorithm of the WDT function can be simply described as a counting
process. The Time-Out Interval can be set through software programming. The
availability of the time-out interval settings by software or hardware varies from
boards to boards.
WADE-8041 allows users control WDT through dynamic software programming. The
WDT starts counting when it is activated. It sends out a signal to system reset or to
non-maskable interrupt (NMI), when time-out interval ends. To prevent the time-out
interval from running out, a re-trigger signal will need to be sent before the counting
reaches its end. This action will restart the counting process. A well-written WDT
program should keep the counting process running under normal condition. WDT
should never generate a system reset or NMI signal unless the system runs into
troubles.
The related Control Registers of WDT are all included in the following sample
program that is written in C language. User can fill a non-zero value into the
Time-out Value Register to enable/refresh WDT. System will be reset after the
Time-out Value to be counted down to zero. Or user can directly fill a zero value into
Time-out Value Register to disable WDT immediately. To ensure a successful
accessing to the content of desired Control Register, the sequence of following
program codes should be step-by-step run again when each register is accessed.
Additionally, there are maximum 2 seconds of counting tolerance that should be
considered into user’ application program. For more information about WDT, please
refer to Winbond W83627HG-AW data sheet.

System Installation
There are two PNP I/O port addresses that can be used to configure WDT,
1) 0x2E:EFIR (Extended Function Index Register, for identifying CR index number)
2) 0x2F:EFDR (Extended Function Data Register, for accessing desired CR)
Below are some example codes, which demonstrate the use of WDT.
//Step1. Enter W83627HG configuration registers mode:
outportb(0x2E, 0x87);
outportb(0x2E, 0x87);
//* Step2. Pin89 to be WDTO
outportb(0x2E, 0x2b);
outportb(0x2E + 1, 0x04);
//* Step3. Select logic device 8:
outportb(0x2E, 0x07);
outportb(0x2E + 1, 0x08);
//* Step4. Config WDT using second to be unit:
outportb(0x2E, 0xf5);
outportb(0x2E + 1, 0x00);
//* Step5. Set WDT time-out time:
outportb(0x2E, 0xf6);
outportb(0x2E + 1, time_out);
//* Step6. Exit configuration registers mode:

WADE-8041 GPIO Programming Guide
There are 8 GPIO pins on WADE-8041. These GPIO pins are from SUPER I/O
(W83627GH-AW) GPIO pins, and can be programmed as Input or Output direction.
J22 pin header is for 8 GPIO pins and its pin assignment as following :
J22_Pin1=GPIO4:from SUPER I/O_GPIO10 with Ext. 4.7K PH
J22_Pin2=GPIO0:from SUPER I/O_GPIO11 with Ext. 4.7K PH
J22_Pin3=GPIO5:from SUPER I/O_GPIO12 with Ext. 4.7K PH
J22_Pin4=GPIO1:from SUPER I/O_GPIO13 with Ext. 4.7K PH
J22_Pin5=GPIO6:from SUPER I/O_GPIO14 with Ext. 4.7K PH
J22_Pin6=GPIO2:from SUPER I/O_GPIO15 with Ext. 4.7K PH
J22_Pin7=GPIO7:from SUPER I/O_GPIO16 with Ext. 4.7K PH
J22_Pin8=GPIO3:from SUPER I/O_GPIO17 with Ext. 4.7K PH
<<<<< Be careful Pin9=GND , Pin10=VCC >>>>>
There are several Configuration Registers (CR) of W83627HG-AW needed to be
programmed to control the GPIO direction, and status(GPI)/value(GPO). CR00h ~
CR2F are common (global) registers to all Logical Devices (LD) in W83627HG. CR07h
contains the Logical Device Number that can be changed to access the LD as needed.
LD7 contains the GPIO10~17 registers.
Programming Guide:
Step1: CR2A_Bit [7.2]. P [1,1,1,1,1,1]; to select multiplexed pins as GPIO10~17 pins
Step2: LD7_CR07h.P [07h]; Point to LD7
Step3: LD7_CR30h_Bit0.P1; Enable LD7
Step4: Select GPIO direction, Get Status or output value.
LD7_CRF0h; GPIO17 ~ 10 direction, 1 = input, 0 = output pin
LD7_CRF2h.P [00h]; Let CRF1 (GPIO data port) non-invert to prevent from confusion
LD7_CRF1h; GPIO17~10 data port, for input pin, get status from the related bit, for
output pin, write value to the related bit.
For example,
LD7_CRF0h_Bit4.P0; Let GPIO14 as output pin
LD7_CRF2h_Bit4.P0; Let CRF1_Bit4 non-inverted
LD7_CRF1h_Bit4.P0; Output “0” to GPIO14 pin (J25_Pin6)
LD7_CRF0h_Bit0.P1; Let GPIO10 as input pin
LD7_CRF2h_Bit0.P0; Let CRF1_Bit0 non-inverted
Read LD7_CRF1h_Bit0; Read the status from GPIO10 pin (J25_Pin1)

How to access W83627HG CR?
In WADE-8041, the EFER = 002Eh, and EFDR = 002Fh.
EFER and EFDR are 2 IO ports needed to access W83627HG-AW CR.
EFER is the Index Port, EFDR is the Data Port.
CR index number needs to be written into EFER first,
Then the data will be read/written from/to EFDR.
To R/W W83627HG-AW CR, it is needed to Enter/Enable Configuration Mode first.
When completing the programming, it is suggested to Exit/Disable Configuration
Mode.
Enter Configuration Mode: Write 87h to IO port EFER twice.
Exit Configuration Mode: Write AAh to IO port EFER.

PASSWORD DISABLED
When a password has been enabled, user will be prompted to enter it every time user
tries to enter Setup. This prevents an unauthorized person from changing any part of
your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to request a
password every time your system is rebooted. This would prevent unauthorized use
of the computer.
User may determine when the password is required within the BIOS Features Setup
Menu and its Security option (see Section 3). If the Security option is set to “System”,
the password will be required both at boot and at entry to Setup. If set to “Setup”,
prompting only occurs when trying to enter Setup.

BIOS configures the system according to the Setup selections stored in CMOS. After
saving the values the system is restarted again.
Exit Without Saving
Pressing <Enter> on this item asks for confirmation:

Troubleshooting
This chapter provides a few useful tips to quickly get WADE-8041 running with
success. As basic hardware installation has been addressed in Chapter 2, this chapter
will primarily focus on system integration issues, in terms of BIOS setting, and OS
diagnostics.
5.1
Hardware Quick Installation
Intel Socket 479 Pentium M / Celeron M processor
Please kindly refer the figure 3-1 at chapter 3, user has to configure CPU into the
actuator more gentle and locks the latch on the actuator, don’t forcible push CPU into
socket.
5.2
BIOS Setting
It is assumed that users have correctly adopted modules and connected all the
devices cables required before turning on ATX power. CPU, CPU Fan, 184-pin DDR
SDRAM, keyboard, mouse, floppy drive, IDE hard disk, VGA connector, device
cables, ATX power cable are good examples that deserve attention. With no assurance
of properly and correctly accommodating these modules and devices, it is very
possible to encounter system failures that result in malfunction of any device.
To make sure that you have a successful start with WADE-8041, it is recommended,
when going with the boot-up sequence, to hit “DEL” key and enter the BIOS setup
menu to tune up a stable BIOS configuration so that you can wake up your system far
well.
Loading the default optimal setting
When prompted with the main setup menu, please scroll down to “Load Optimal
Defaults”, press “Enter” and “Y” to load in default optimal BIOS setup. This will
force your BIOS setting back to the initial factory configuration. It is recommended to
do this so you can be sure the system is running with the BIOS setting that Portwell
has highly endorsed. As a matter of fact, users can load the default BIOS setting any
time when system appears to be unstable in boot up sequence.
Auto Detect Hard Disks
In the BIOS => Standard CMOS setup menu, pick up any one from
Primary/Secondary Master/Slave IDE ports, and press “Enter”. Setup the selected
IDE port and its access mode to “Auto”. This will force system to automatically pick
up the IDE devices that are being connected each time system boots up.

Troubleshooting
Improper disable operation
There are too many occasions where users disable a certain device/feature in one
application through BIOS setting. These variables may not be set back to the original
values when needed. These devices/features will certainly fail to be detected.
When the above conditions happen, it is strongly recommended to check the BIOS
settings. Make sure certain items are set as they should be. These include the COM1/
COM2/COM3/COM4 ports, USB ports, external cache, on-board VGA and Ethernet.
It is also very common that users would like to disable a certain device/port to
release IRQ resource. A few good examples are
Disable COM1/COM4 serial port to release IRQ #4
Disable COM2/COM3 serial port to release IRQ #3
Etc…
A quick review of the basic IRQ mapping is given below for your reference.
