Introduction
This user manual is used for ABN-102 and ABN-112 standard universal
PCI Ethernet controllers. The basic design of both Ethernet controller cards is
identically: both equipped with Intel 21152 Transparent PCI-to-PCI Bridge,
dual Ethernet controller chips, dual Ethernet ports and universal 32-bit
standard PCI. To enhance Ethernet performance, the ANB-102 is designed
with Intel 82540EM Gigabit Ethernet Controllers instead of Intel 82551
10/100Mbps Ethernet controllers which is applied on ABN-112. The further
detail of both products will be covered in the following chapters.

Bypass and Watchdog
Timer (WDT)
5.1 Bypass Function
The bypass function on ABN-102 and ABN-112 is used to connect two
independent Ethernet ports, and the function is set when the power is off
or determined by software
5.2 WDT Function
A Watchdog Timer (WDT) is a piece of hardware that can be
used to automatically detect software anomalies and set the
system to another state. Generally, the WDT is depending on
a counter, which counts from an initial value to zero. When the
counter reach zero, WDT times out, and the system will
automatically shift to another predefined state. On the other
side, if the WDT is refreshed before every expiration, then the
system remaines at the same state.
NOTE: WDT works only when JP1 is set at pin 2-3 ( Bypass function enabled).
5.3 I/O Port Allocation for Bypass and WDT Function
5.3.1 WDT enable
To enable WDT and refresh I/O port, the user can write to the port
0FF0h with data.
NOTE: 0FF0h is a write only (W/O) port
ABN-102-112 User’s Guide 19
The data is in 8-bit format
EXAMPLE: xx000001b (1) ~ xx111111b (63)
NOTE: xx000000b (0) is NOT an allowed data.
NOTE: The least significant 5 bits are the data bits, and two most
significant bits (bit 6 and 7) are no concerned.
The WDT time-out Period (Twd) is determined by the 5-bit data
multiplied with times resolution. The default time resolution is
0.25 second.
EXAMPLE: if the data value = 001010b(10), then the
Twd value = 10 x 0.25 = 2.5 seconds.
NOTE: Valid Twd value range: 0.25 ~ 15.75 seconds.
NOTE: Twd value can be changed after every refresh action but before
expiration.
When WDT enabled, the Ethernet ports will enter Normal State,
and every refresh action before WDT time-out will keep the
Ethernet ports remain at Normal State. If WDT expires without
any refresh, due to software hanging or other software limitation,
the Ethernet ports will enter Bypass State immediately.
NOTE: Twd tolerance depends on the PCI clock on ABN-102/112, and it
is about 7 ~ 5%. i.e. it is better to refresh WDT within 93% Twd
since last refresh action.
5.3.2 WDT disable
To disable WDT counting, the software has to read this read-only
(R/O) I/O port 0FF1h.
5.3.3 Software Set to Normal State
To set the two Ethernet Ports in Normal State, the software has
to read this I/O port 0FF2h (R/O).
5.3.4 Software Set to Bypass State
ABN-102-112 User’s Guide 20
To set two Ethernet Ports in Bypass State, the software has to
read this I/O port 0FF3h (R/O).
5.3.5 Sample Code
#include <stdio.h>
#include <unistd.h>
#include <asm/io.h>
#define WDTen 0xFF0 /* WDT enable port */
#define WDTdis 0xFF1 /* WDT disable port */
#define NState 0xFF2 /* Normal State port */
#define BpState 0xFF3 /* Bypass State port */
#define Twd 40 /* WDT time period */
main()
{
iopl(3); /* Open all ports */
outb(Twd, WDTen); /* Enable WDT with time period
value*/
inb(WDTdis); /* Disable WDT function */
inb(NState); /* Set Normal State */
inb(BpState); /* Set Bypass State */
}
