LCD display connection
The card CPU 1021/A allows, by means of connector J5, interface
with a wide display of colors with TFT technology and LVDS input
To connect an LCD display to the card CPU 1021/A, proceed as
follows:
•Set the three jumpers JP7, JP8, JP9 according to the table for
the types of LCD panels. Refer to the chapter Hardware setup.
•Connect the inverter to the connector J11.
•Set the jumpers JP1 (power supply), JP2 –JP3 –JP16 –JP17,
JP18 (type of inverter) referring to the chapter Hardware setup.
•Power on the system, enter SETUP and set the video output to
the desired mode.
In SETUP, adjust the brightness of the lamps of the LCD panel (the
range of values is 0-100 in steps of 10).
Floppy disk controller
The floppy disk controller integrated on the motherboard allows
management of 1 floppy disk drives with capacity of 360 KB, 720 KB,
1.2 MB, 1.44 MB, 2.88 MB.
IDE controller

that can manage a master unit (default). Mass memories are
supported of the following types: Compact FLASH.
SATA controller
The CPU 1021/A integrates a controller for three SATA channels that
can support mass memories like hard disk and DVD.
On the motherboard there are 4 SATA connectors (J12 –J14 –J15
–J16), J14 and J15 refer to the same channel.

Parallel port
The optional parallel port (through an additional card that is in
alternative to port COM3) is compatible with the Centronics standard.
The mode of the parallel port (SPP,ECP, EPP) and the I/O address
and any IRQ and DMA can be arranged via the Setup.
Serial ports
The system allows the use of 4 serial ports : two equipped with
driver/receiver RS232 (COM 1 and COM2), one multi-standard (RS-
232/422/485) optional on the additional card in alternative to the
parallel port and one dedicated to the touchscreen (COM4).
COM3 is equipped with an automatism for the management of the
direction of the transmission line The port is normally in reception
state. If there is a transmission request, it switches the line driver to
transmission only for the time needed to complete it. The multi-
standard, optically insulated COM3 card is optionally available.
The arrangement of the addresses of I/O, of the IRQ's and of the
standards of the ports can be selected via software by means of the
system Setup.
LAN1 10/100/1000 Mbps Port
The CPU 1021/A integrates a LAN sub-system (local network) PCI at
10/100/1000 Mbps (full duplex), based on the chip Intel 82574L.
Through a connector RJ45 it is possible to connect to a hub at
10Mbps or 100Mbps or 1Gbps an Ethernet local network 10BASE-T
or 100BASE-TX or 1000BASE-TX.
The chip supports self-negotiation of the speed of communication
(IEEE802.3u).

Description
Asem S.p.A. 7
LAN2 10/100/1000(opt.) Mbps Port
The CPU 1021/A integrates a LAN sub-system (local network) at 1
Gigabit (full duplex) with integrated controller in the southbridge
(ICH8M) and part of output based on the chip Intel 82566M. Via a
connector RJ45 it is possible to connect to a hub at 10Mbps,
100Mbps or 1 Gigabit an Ethernet local network 10BASE-T,
100BASE-TX or 1 Gigabit..
The chips support self-negotiation of the speed of communication
(IEEE802.3u).
USB (Universal Serial Bus) ports
The system supports 8 ports USB 2.0. Serial transfers are supported
up to 480 Mbit/s. Four ports (USB0~3) are available on the rear
external connectors. Two ports (USB4~5) are available on the
connectors on the front of the system.
The signals for the 2 ports (USB 6~7) are present on the pin-strip
J18 (for internal use) and can be carried on to a bracket via an
adaptor cable for 2 USB ports 2.0
Firmware Hub
The FWH is a serial Flash of 8 Mbits that contains the system BIOS
and the video BIOS.
The BIOS (Phoenix Technologies) is composed of modules in the
Eprom in compressed format that are decompressed when the
system is started. After the bootstrap, the system BIOS part is seen
at the addresses E0000h –FFFFFh while the BIOS video at the
addresses C0000h - CFFFFh.
The Flash Eprom can be re-programmed via the utility PHLASH16,
thus allowing easy updating of the firmware.
On the motherboard there are two serial EEPROM SPI 16Mbit
containing system and BIOS configuration data.

Real time clock and CMOS memory
The Real Time Clock and the RAM CMOS (backed up by a lithium
battery) are integrated into the southbridge ICH8M.
The configuration selected via the system setup menus is saved in
the 256 locations of non-volatile RAM.
Compact Flash
The connector J17 can host devices of Compact Flash Types 1 and
2. These devices are based on Flash technology and allow
emulation of hard disks with the possibilities reading, writing, and
variable capacity. The PATA type interface uses one of the two
devices that can be connected to the primary IDE channel and with a
jumper it can be set as master or slave.
Hardware monitor
The hardware monitor device allows monitoring of the temperature of
the microprocessor and of the card, of the supply voltages and of the
speed of the tachometric fans.
These amounts can be shown on a window in a Microsoft
environment through the use of a specific programmed provided in
the support CD included with the card.

Watch-dog
The watch-dog allows system restart after a crash caused by
hardware or software.
It is based on a timer with a period that can be programmed from
among four pre-defined values. The application software must
constantly refresh the watch-dog with a period that is less than that
of the timer, so as to keep the watch-dog from intervening.
If this refresh does not occur, at the end of the pre-established time:
•the watch-dog LED on the CPU 1021/A will come on
•bit 0 of the port I/O 568h will be set to logic state 1. The
application software will subsequently be able to read it.
•There will then be generated a Reset, based on the settings
made by the user.

Generation of Reset (restart system)
After intervention of the watch-dog, the LED and the bit 0 of the port
568h can be returned to the initial conditions through a command of
the application software or by pressing the key Reset watch-dog.
States of watch-dog
The watch-dog has four operating states:
1. Idle
(initial inactive state) waiting for command out 565h=80h to
change to Set.
2. Set
waiting for command out 566h=nh (0<n<=FFh), to set the WD
intervention time (from 0 up to 255 seconds) and change to Run.

CPU 1021/A User’s Guide
10 Asem S.p.A.
3. Run
waiting for command out 566h=nh (0<n<=FFh), to refresh the
WD, resetting the timer count. If there is no refresh and the timer
expires, it changes to Expired.
4. Expired
after the watch-dog timer has expired:
•the watch-dog LED on the CPU 1021/A will come on
•bit 0 of the port I/O 568h (watch-dog in Expired state) will be
set to logic state 1.The application software will
subsequently be able to read it.
•There will then be generated a Reset, based on the settings
made by the user.
To change back from Expired state to Idle it is necessary:
- To set logic state 0for bit 0 of port 568h
- To set logic state 0for the 8 bits of port 566h
To turn off the watch-dog LED it is necessary to press Reset watch-
dog button.
Summary of commands
The watch-dog is capable of receiving the following commands from
the application software:
Command
Effect
out 565h, 80h
Changes the watch-dog from Idle state to Set
out 566h, nh (0<n<=FFh)
Switches state "Set" to "Run" and also must be
periodically issued while the WD is in a state of
"Run" to make a refreshing and avoid the time-out.
out 568h, 0h
converts the bit 0 of port 568h to 0 (zero bit
indicates that WD Expired)
out 566h, 0h
Goes from "Expired" to "Idle" and is ready to be
rearmed.
The addresses of I / O mentioned refer to the programming carried
by the version of BIOS 8921965A.04. To obtain the values
programmed by earlier versions add 180h to any address.
