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 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. 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 may result in expensive repairs. The following measures should generally 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 component, place all materials on an antic static surface.
Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom of every board.

2. SYSTEM CONTROLLER
This chapter describes the major structure of the AR-B1462 CPU board. The following topics are covered:
l DMA Controller l Keyboard Controller l Interrupt Controller l Real-Time Clock and Non-Volatile RAM l Timer l Serial Port l Parallel Port
2.1 DMA CONTROLLER
The equivalent of two 8237A DMA controllers are implemented in the AR-B1462 board. Each controller is a four­channel 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 speeding 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” interruption may be used for both send and receive routines.

AR-B1462 User¡¦s Guide
2.3 INTERRUPT CONTROLLER
The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1462 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 NMI CTRL1
IRQ 0 IRQ 1 IRQ 2

2.6 SERIAL PORT
The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial format on the transmit side and 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 also included to use this 16x clock to drive the receiver logic. Also included in the ACE a completed MODEM control capability, and a processor interrupt system that may be software tailored to the computing time required handle the communications link.
The following table is summary of each ACE accessible register

Figure 2-2 Printer Status Buffer
NOTE: X presents not used.
Bit 7: This signal may become active during data entry, when the printer is off-line during printing, or when the
print head is changing position or in an error state. When Bit 7 is active, the printer is busy and can not accept data.
Bit 6: This bit represents the current state of the printer’ s ACK signal. A0 means the printer has received the
character and is ready to accept another. Normally, this signal will be active for approximately 5 microseconds before receiving a BUSY message stops.
Bit 5: A1 means the printer has detected the end of the paper.
Bit 4: A1 means the printer is selected.
Bit 3: A0 means the printer has encountered an error condition.

(5) Printer Control Latch & Printer Control Swapper
The system microprocessor can read the contents of the printer control latch by reading the address of printer control swapper. Bit definitions are as follows:
1234567 0
X X
STROBE AUTO FD XT INIT SLDC IN
IRQ ENABLE
DIR(write only)
Figure 2-3 Bit’ s Definition
NOTE: X presents not used.
Bit 5: Direction control bit. When logic 1, the output buffers in the parallel port are disabled allowing data driven
from external sources to be read; when logic 0, they work as a printer port. This bit is write 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.

AR-B1462 User¡¦s Guide
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 [shorting plug] 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. Place the jumper over 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 locations of the AR-B1462 jumper pins, and the factory-default setting.
CAUTION: Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist strap
or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can permanently damage electronic components.
3.2.1 FDD Port Connector (CN8)
The AR-B1462 provides a 34-pin header type connector for supporting up to two floppy disk drives.
