0.7 STATIC ELECTRICITY PRECAUTIONS

Before removing the board from its anti-static bag, read this section about static electricity precautions. Static electricity is a cons tant d anger to computer syst ems. T he charge that c an buil d up in your body m ay be more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic precautions whenever you use or handle computer components. Although areas with humid climates are much less prone to static build-up, it is always best to safeguard against accidents that may result in expensive repairs. The following measures should be sufficient to protect your equipment from static discharge:

• Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded wrist strap).

• When unpacking and handling the board or other system components, place all materials on an anti-static surface.

• Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom of the board.

Introduction

Packing List

Features

1.1 INTRODUCTION

The AR-B9616 is a industrial grade CPU card that has been designed to withstand continuous operation in harsh environments. The total on-board memory for the AR-B9616 can be configured from 1MB to 32MB by using all 72-pin type DRAM devices.

The 8 layers PCB CPU card is equipped with an IDE HDD interface, a floppy disk drive adapter, 1 parallel port, 2 serial ports, and a watchdog timer. The dimension is as compact as 100mmX160mm. Its highly condensed features make it an ideal cost/performance solution for high-end commercial and industrial applications where CPU speed and mean time between failures is critical. A watchdog timer, which has a software programmable time-out interval, is also provided on this CPU card. It ensures that the systems will not hang-up if a program cannot execute normally.

The AR-B9616 is implemented with M1489 and M1487 chipset incorporate a memory controller, parity generation and checking, two 8237 DMA controllers, two 8259 interrupt controllers, one 8254 timer/counter, an address buffer and a data buffer.

A super I/O chip (SMC37C669) is embedded in the AR-B9616 card. It combines functions of a floppy disk drive adapter, a hard disk drive (IDE) adapter, two serial (with 16C550 UART) adapters and 1 parallel adapter. Setting the BIOS setup program can do the I/O port configurations.

As an UART, the chip supports serial to parallel conversion on data characters received from a peripheral device or a MODEM, and parallel to serial conversion on data character received from the CPU. The UART includes a programmable baud rate generator; complete MODEM control capability and a processor interrupt system. As a parallel port, the SMC37C669 provides the user with a fully bi-directional parallel centronics-type printer interface.

2 SYSTEM CONTROLLER

This chapter describes the major structure of the AR-B9616 CPU board. The topics are covered as follow:

! DMA Controller ! Keyboard Controller ! Interrupt Controller

Real-Time Clock and Non-volatile RAM

! Serial Port ! Parallel Port

2.1 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B9616 board. Each controller is four channels DMA device, which will generate the memory addresses and control signals necessary to transfer information directly between a peripheral device and memory. This allows high-speed information transfer with less CPU intervention. The two DMA controllers are internally cascaded to provide four DMA channels for transfers to 8-bit peripherals (DMA1) and three channels for transfers to 16-bit peripherals (DMA2). DMA2 channel 0 provides the cascade interconnection between the two DMA devices, thereby maintaining IBM PC/AT compatibility.

Following is the system information of DMA channels:

DMA Controller 1 DMA Controller 2

Channel 0: Spare Channel 4: Cascade for controller 1 Channel 1: IBM SDLC Channel 5: Spare Channel 2: Diskette adapter Channel 6: Spare Channel 3: Spare Channel 7: Spare

Table 2-1 DMA Channel Controller

2.2 KEYBOARD CONTROLLER

The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the system to poll its status register to determine when data is available.

Data can be written to the keyboard by writing data to the output buffer of the keyboard controller.

Each byte of data is sent to the keyboard controller in series with an odd parity bit automatically inserted. The keyboard controller is required to acknowledge all data transmissions. Therefore, another byte of data will not be sent to keyboard controller until acknowledgment is received for the previous byte sent. The “output buffer full” interrupt may be used for both send and receive routines.

Page 9

AR-B9616 User’s Guide

2.3 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B9616 board. They accept requests from peripherals, resolve priorities on pending interrupts in service, issue interrupt requests to the CPU, and provide vectors which are used as acceptance indices by the CPU to determine which interrupt service routine to execute.

Following is the system information of interrupt levels:

InInterrupt Level

2.5 SERIAL PORT

The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are not only used to convert parallel data to a serial format on the transmit side but also used to convert serial data to parallel on the receiver side. The serial format, in order of transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one, one and half (five-bit format only) or two stop bits. The ACEs are capable of handling divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter logic.

Provisions are not only included the use of 16x clock to drive the receiver logic but also included in the ACE as a complete MODEM control capability, and a processor interrupt system that may be software tailored to the computing time required to handle the communications link.

The following table is summary of each ACE accessible register

(A ju mp er bl oc k is a s ma ll pl as ti c- en ca se d c on du c to r [ sh or ti ng pl ug ] t ha t s li ps ov er th e pin s .) To change a jumper setting, remove the jumper from its cur rent location with your fin gers or sm all needl e-nosed plier s. Pl a c e t he j u m pe r o ve r the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.

We will show the locatio ns of t he AR -B96 16 j um per p in s, a nd the fact ory -default setting. Note that the square pin of each jumper block is pin 1.

CAUTION: Do not touch any electronic component unless you are safely grounded. W ear a grounded wrist strap

or touch an exposed metal part of the system unit chassis. A static discharge from your fingers can permanently damage electronic components.

The BUSCLK signal of the I/ O channel is asynchronous to the CPU clock. This signal goes high during power-up, low line-voltage or hardware reset The System Address lines run from bit 0 to 19. They are latched onto the falling edge of "BALE" The Unlatched Address line run from bit 17 to 23

System Data bit 0 to 15

The Buffered Address Latch Enable is used to latch SA0 - SA19 onto the falling edge. This signal is forced hi gh duri ng DMA cycles The I/O Channel Check is an active low signal which indicates that a parity error exist on the I/O board This signal lengthens the I/O, or memory read/write cycle, and should be held low with a valid address The Interrupt Request signal indicates I/O service request attention. They are prioritized in the following sequence : (Highest ) I RQ 9, 10, 11, 12, 13, 15, 3, 4, 5, 6, 7 (Lowest) The I/O Read signal is an active low signal which instructs the I/O device to drive its dat a onto the data bus The I/O write signal is an active low signal which instruct s the I/O device to read data from the data bus The System Memory Read is low while any of the low 1 mega bytes of memory are being used The Memory Read signal is low while any mem ory l ocation is being read

The System Memory Write is low while any of the low 1 mega byt es of memory is bei ng written The Memory Write s i gnal i s low while any memory location is bei ng writt en

DMA Request channels 0 to 3 are for 8-bit data transfers . DMA Request channels 5 to 7 are for 16-bit data transfers. DMA request should be held high until the corresponding DMA has been completed. DMA request priority is in the following sequenc e:(Highest) DRQ 0, 1, 2, 3, 5, 6, 7 (Lowest) The DMA Acknowledges 0 to 3, 5 to 7 are the corresponding acknowledge signals for DRQ 0 to 3 and 5 to 7 The DMA Address Enable is high when the DMA controller is driving t he address bus. It is low when the CPU is driving the address bus This signal is used to indicate a memory refresh cycle and can be driven by the microprocessor on the I/O channel Terminal Count provides a pulse when the terminal count for any DMA channel is reached The System Bus High Enabl e i ndi cates the high byte SD8 - SD15 on the data bus The MASTER is the signal from the I/O processor which gains control as the master and should be held low for a maximum of 15 microseconds or system memory may be l ost due to the lack of refresh The Memory Chip Select 16 indicates that the present data transfer is a 1-wait state, 16-bit data memory operati on The I/O Chip Select 16 indicates that the present data transfer is a 1-wait state, 16-bit data I/O operation The Oscillator is a 14.31818 MHz signal The Zero Wait State indicates to the microprocessor that the present bus cycle can be completed without insert i ng addi tional wait cycle

3.2.10 CPU Setting

The AR-B9616 accepts many t ypes of m icropro cessor s, such as Intel/AM D/CY RIX/ST 486 DX/DX 2/DX4 & 5X86. All of these CPUs include an integer processing unit, floating-point processing unit, memory-management unit, and cache. They can give two to ten-fold performance improvement in speed over the 386 processor. It depends on the clock speeds used and specific application. Like the 386 processor, the 486 processor includes both segment-based and page-based memory protection schemes. On-chip instruction pipelining reduces instruction-processing time. By performing fast, on-chip memory management and caching, the 486 processor relaxes requirements for memory response for a given level of system performance.

This section describes how to use the Watchdog Timer, disabled, enabled, and trigger. The AR-B9616 is equipped with a programmable time-out period watchdog timer. Your program can enable this

watchdog timer. Once you have enabled the watchdog timer, the program should trigger it every time before it times out. If your program fails to trigger or disable this timer before it time s ou t be cau se o f system hang-up, it w ill generate a reset signal to reset the system. The time-out period can be programmed to be 3 to 42 seconds.

5.3.1 Watchdog Timer Setting

The watchdog timer is a circuit that may be used from your program software to detect crashes or hang-ups. Whenever the watchdog timer is enabled, the LED (LED1) will blink to indicate that the timer is counting. The watchdog timer is automatically disabled after reset.

Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it times-out. After you trigger the watchdog timer, it will be set to zero and start to count again. If your program fails to trigger the watchdog timer before time-out, it will generate a reset pulse to reset the system to tell your program that the watchdog is times out.

The factor of the watchdog timer time-out constant is approximately 6 seconds. The period for the watchdog timer time-out period is between 1 to 8 timer factors.

If you want to reset your system when watchdog times out, the following table listed the relation of timer factors between time-out periods.

Time Factor Time-Out Period (Seconds)

Table 5-1 Time-Out Setting

5.3.2 Watchdog Timer Enabled

To enable the watchdog t im er, you have to output a by te of timer factor to the watchdog register whose address is 76H or 214H. The following is a BASICA program, w hich de mon strat es how to enable the watchdog timer an d set

the time-out period at 24 seconds. 1000 REM Points to command register 1010 WD_REG% = 76H 1020 REM Timer factor = 84H (or 0C4H) 1030 TIMER_FACTOR% = %H84 1040 REM Output factor to watchdog register 1050 OUT WD_REG%, TIMER_FACTOR% .,etc.

5.3.3 Watchdog Timer Trigger

After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog

register at least once ev ery tim e-out period to its prev iou s s ett ing. You can change the time-out period by writing

another timer factor to the watchdog register at any time, and you must trigger the watchdog before the new

time-out period in next trigger. Below is a BASICA program, which demonstrates how to trigger the watchdog

timer:

2000 REM Points to command register 2010 WD_REG% = 76H 2020 REM Timer factor = 84H (or 0C4H) 2030 TIMER_FACTOR% = &H84 2040 REM Output factor to watchdog register 2050 OUT WD_REG%, TIMER_FACTOR% .,etc.

6.1 BIOS SETUP OVERVIEW

BIOS is a program used to initialize and set up the I/O system of the computer, which includes the ISA bus and connected devices such as the video display, diskette drive, and the keyboard.

These BIOS provides a menu-based interface to the console subsystem. The console subsystem contains special software, called firmw are that intera cts dire ctly w ith the har dware co mponent s an d facil itates interacti on betw een the system hardware and the operation system.

The BIOS Default Values ensure that the system will function at its normal capability. In the worst situation the user may have corrupted the original settings set by the manufacturer. After the computer is turned on, the BIOS will perform a diagnostics of the system and display the size of the memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu will show on the screen.

The BIOS Setup main menu ex ists 11 opti ons. Use the [Up/Dow n] arrow key to highlig ht the opti on that y ou wish t o modify, and then press the [Enter] key to assure the option and configure the functions.

To highlight the <Time> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date. Follow the hour, minute and second format.

User can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information on how to create this file, please refer to the MS-DOS manual.

6.2.2 Floppy Setup

The <Standard CMOS Setup> option record the types of floppy disk drives installed in system.

To enter the configuration value for a particular drive, highlight its corresponding field and then select the drive type using the left-or right-arrow key.

6.2.3 Hard Disk Setup

The BIOS supported 48 types for user setting, The BIOS supported <Pri Master> and <Pri Slave> two items that user can install up to two hard disks. The master and slave jumper adjusting, please refer to the hard disk’s installation description and the hard disk jumper setting.

You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your IDE drives during boot up. This will allow you to change your hard drives (with the power off) and then power on without having to reconfigure your hard drive type. If you use older hard disk drives, which do not support this feature, then you must configure the hard disk drive in the standard method as described above by the <USER> option. The user type referring to the hard disk type setting, it always sets the <Cyln>, <Head> and <Sec> the three items, the BIOS will find the hard disk correct type.

6.2.4 Virus Protection

This option protects the boot sector and partition table of your hard disk against accidental modifications. Any attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can either allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your system. The default setting is Disabled. This setting is recommended because conflicts with new operating systems. Installation of new operating systems requires that you disable this to prevent write errors.

This category speeds up Power On Self Test (POS T ) aft er y o u power on the computer. If it is set to Enabled, BIOS will shorten or skip some check items during POST.

(2) Boot Up Sequence

The option determines where the system looks first for an operating system. The default setting is to check first the hard disk and then the floppy drive, and last the CDROM.

(3) Boot Up Num-Lock

The item is used to active the Num Lock function upon system boot. If the setting is on, after user booted computer, the light of Num Lock is bright, and user can use the number key.

(4) Floppy Drive Swap

The option reverses the drive letter assignments of your floppy disk drives in the Swap A, B setting, otherwise leave on the default setting of Disabled (No Swap). This works separately from the BIOS Features floppy disk swap feature. It is functionally the same as physically interchanging the connectors of the floppy disk drives. When enabled, the BIOS swaps floppy drive assignments so that Drive A becomes Drive B, and Drive B becomes Drive A under DOS.

(5) Floppy Drive Seek

If the <Floppy Drive Seek> item is setting Enabled, the BIOS will seek the floppy <A> drive one time.
