Static electricity is a constant danger to computer systems. The charge that can build up in your body may be more than sufficient to damage integrated circuits on any PC board. Therefore, it is 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. 4 AR-B1551NP User＇s Guide 1.

SYSTEM CONTROLLER This chapter describes the main structure of the AR-B1551NP CPU board. The following topics are covered: � Microprocessors � DMA Controller � Keyboard Controller � Interrupt Controller � Serial Port � Parallel Port 2.1 MICROPROCESSOR The AR-B1551NP uses the NS GEODE GX1 CPU, it is an advanced 32-bit x86 compatible processor offering high performance, fully accelerated 2D graphics, a 64-synchronous DRAM controller and a PCI bus controller, all on a single chip. This latest generation of the MediaGX processor enables a new class of premium performance notebook/desktop, and IPC computer designs. The MediaGX MMX enhanced processor companion chips provide advanced video and audio functions and permit direct interface to memory. This high-performance 64-bit processor is x86 instruction set compatible and supports MMX technology. This processor is the latest member of the NS MediaGX family, offering high performance, fully accelerated 2D graphics, synchronous memory interface and a PCI bus controller, all on a single chip. As described in separate manuals, the CS5520 and the CS5530 I/O Companion chips fully enable the features of the MediaGX processor with MMX support. These features include full VGA and VESA video, 16-bit stereo sound, IDE interface, ISA interface, SMM power management, and AT compatibility logic. In addition, the newer CS5530 provides an Ultra DMA/33 interface, MPEG2 assist, and is AC97 Version 2.0 audio compliant. In addition to the advanced CPU features, the MediaGX processor integrates a host of functions, which are typically implemented with external components. A full-function graphics accelerator provides pixel processing and rendering functions. The NS MediaGX MMX-Enhanced Processor represents a new generation of x86-compatible 64-bit microprocessors with sixth-generation features. The decoupled load/store unit (within the memory management unit) allows multiple instructions in a single clock cycle. Other features include single-cycle execution, single-cycle instruction decode, 16KB write-back cache, and clock rates up to 266MHz. These features are possible by the use of advanced-process technologies and superpipelining. 2.2 DMA CONTROLLER The equivalent of two 8237A DMA controllers are implemented on the AR-B1551NP board. Each controller is a four-channel DMA device that 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. The Following is the system information for the DMA channels: Slave with four 8-bit chnls Master with three 16-bit chnls DMA Controller 1 DMA Controller 2 Channel 0: Spare Channel 4(0): Cascade for controller 1 Channel 1: IBM SDLC Channel 5(1): Spare Channel 2: Diskette adapter Channel 6(2): Spare Channel 3: Spare Channel 7(3): Spare DMA Channel Controller 7 AR-B1551NP User＇s Guide 2.3 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 a 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” interruption may be used for both send and receive routines. 2.4 INTERRUPT CONTROLLER The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1551NP 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. These two controllers are cascaded with the second controller representing IRQ8 to IRQ15, which is rerouted through IRQ2 on the first controller. The following is the system information of interrupt levels: Interrupt Level Description NMI Parity check CTRL1 CTRL2 System timer interrupt from timer 8254 IRQ0 keyboard output buffer full IRQ1 Rerouting to IRQ8 to IRQ15 IRQ2 IRQ8:Real time clock IRQ9:Reserved IRQ10:LAN adapters(based on PCI INT routing) IRQ12:Reserved for PS/2 mouse IRQ13:Math.Co-processor IRQ14:Hard disk adapter IRQ15:Hard disk adapter IRQ3 Serial port(depends on setup assignment) IRQ4 Serial port(depends on setup assignment) IRQ5 Reserved IRQ6 Reserved for floppy disk adapter IRQ7 Parallel port 1 Interrupt Controller 8 AR-B1551NP User＇s Guide 2.4.1 I/O Port Address Map Hex Range Device 000-01F DMA controller 1 020-021 Interrupt controller 1 022-023 Cyrix CS5530 040-04F Timer 1 050-05F Timer 2 060-06F 8042 keyboard/controller 070-071 Real-time clock (RTC), non-maskable interrupt (NMI) 080-09F DMA page registers 0A0-0A1 Interrupt controller 2 0C0-0DF DMA controller 2 0F0 Clear Math Co-processor 0F1 Reset Math Co-processor 0F8-0FF Math Co-processor 170-178 Reserved for Fixed disk 1 1F0-1F8 Fixed disk 0 201 Reserved for Game port 208-20A EMS register 0 210-213 SSD 214 WatchDog 218-21A EMS register 1 278-27F Parallel printer port (depends on setup assignment) 290-293 SSD 2E8-2EF Serial port (depends on setup assignment) 2F8-2FF Serial port (depends on setup assignment) 300-31F Prototype card/streaming type adapter 320-33F Reserved 378-37F Parallel printer port (depends on setup assignment) 380-38F SDLC, bisynchronous 3A0-3AF Bisynchronous 3B0-3BF Monochrome display and printer port 3 (LPT 3) 3C0-3CF EGA/VGA adapter 3D0-3DF Color/graphics monitor adapter 3E8-3EF Serial port 3 (depends on setup assignment) 3F0-3F7 Reserved for diskette controller 3F8-3FF Serial port (depends on setup assignment) I/O Port Address Map 9 AR-B1551NP User＇s Guide 2.4.2 Real-Time Clock and Non-Volatile RAM The AR-B1551NP contains a real-time clock compartment that maintains the date and time in addition to storing configuration information about the computer system. It contains 14 bytes of clock and control registers and 114 bytes of general purpose RAM. Because of the use of CMOS technology, it consumes very little power and can be maintained for long periods of time using an internal Lithium battery. The contents of each byte in the CMOS RAM are listed as follows: Address Description 00 Seconds 01 Second alarm 02 Minutes 03 Minute alarm 04 Hours 05 Hour alarm 06 Day of week 07 Date of month 08 Month 09 Year 0A Status register A 0B Status register B 0C Status register C 0D Status register D 0E Diagnostic status byte 0F Shutdown status byte 10 Diskette drive type byte, drive A and B 11 Fixed disk type byte, drive C 12 Fixed disk type byte, drive D 13 Reserved 14 Equipment byte 15 Low base memory byte 16 High base memory byte 17 Low expansion memory byte 18 High expansion memory byte 19-2D Reserved 2E-2F 2-byte CMOS checksum 30 Low actual expansion memory byte 31 High actual expansion memory byte 32 Date century byte 33 Information flags (set during power on) 34-7F Reserved for system BIOS Real-Time Clock & Non-Volatile RAM 2.4.3 Timer The AR-B1551NP provides three programmable timers, each with a timing frequency of 1.19 MHz. Timer 0 The output of this timer is tied to interrupt request 0. (IRQ 0) Timer 1 This timer is used to trigger memory refresh cycles. Timer 2 This timer provides the speaker tone. Application programs can load different counts into this timer to generate various sound frequencies. 10 AR-B1551NP User＇s Guide 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, 1.5 (in a five-bit format only) or two stop bits (in a 6,7, or 8-bit format). The ACEs are capable of handling divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter logic. The provision is not only included the use of this 16x clock to drive the receiver logic. But also included in the ACE as a completed MODEM control capability, and a processor interrupt system that may be software tailored to the computing time required to handle the communications link.

When logic 1, the output buffers in the parallel port are disabled allowing data driven Bit 5: from external sources to be read; when logic 0, they work as a printer port. This bit is writing only. Bit 4: A1 in this position allows an interrupt to occur when ACK changes from low state to high state. Bit 3: A1 in this bit position selects the printer. Bit 2: A0 starts the printer (50 microseconds pulse, minimum). Bit 1: A1 causes the printer to line-feed after a line is printed. Bit 0: A0.5 microsecond minimum highly active pulse clocks data into the printer. Valid data must be present for a minimum of 0.5 microseconds before and after the strobe pulse. 14 AR-B1551NP User＇s Guide 3. SETTING UP THE SYSTEM This section describes pin assignments for the system’s external connectors and the jumper settings. � Overview � System Setting 3.1 OVERVIEW AR-B1551NP is a Pentium Grade CPU Board with DOC, SSD, and Compact Flash (optional) functions. This section provides the hardware’s jumper settings, the connectors’ locations, and the pin assignments. The #1 pin assignments have all been designed on the right side of the board with a “block” indication on the diagram. External System Location 3.2 SYSTEM SETTING Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks. (A jumper block is a small plastic-encased conductor that slips over the pins.) To change a jumper setting, remove the jumper from its current location with your fingers or small needle-nosed pliers.

The AR-B1570 is equipped with a programmable time-out period watchdog timer that occupies I/O post 214H. User can use the program to enable the watchdog timer. Once you enable the watchdog timer, the program should trigger it every time before it times out. And because of the system hang up, your program fails to trigger and disable the timer before it times out. It will generate a reset signal to reset the system. The time-out period can be programmed to be 0 to 63 seconds. Time Base Enable(D7) Time Factor (D0-D5) Watchdog Register Counter and Write and Compartor Trigger RESET Watchdog Block Diagram 3.3.1 Watchdog Timer Setting The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up. The Watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your program should 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 or trigger the IRQ 9 signal in order to tell your system that the watchdog time is out. Please refer to the following table in order to properly program Watchdog function D7 D6 D5 D4 D3 D2 D1 D0 1 Enable Reset Time period 0 Disable IRQ 9 25 AR-B1551NP User＇s Guide Users could test watchdog function under ‘Debug’ program as follow: C:>debug � O 214 C8H Generally, watchdog function would reset system after 8 seconds � O 214 0H Disable watchdog function C:>debug � O 214 88H Generally, watchdog function would generate IRQ 9 after 8 seconds � O 214 0H Disable watchdog function 3.3.2 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 every time-out period to its previous setting. 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. 26 AR-B1551NP User＇s Guide 4.
