AR-B1476 User’s Guide 0.6 ORGANIZATION This information for users covers the following topics (see the Table of Contents for a detailed listing): Chapter 1, “Overview”, provides an overview of the system features and packing list. Chapter 2, “System Controller” describes the major structure.
A super I/O chip (SMC37C669) is embedded in the AR-B1476 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. The I/O port configurations can be done by set the BIOS setup program.
AR-B1476 User’s Guide 1.2 PACKING LIST The accessories are included with the system. Before you begin installing your AR-B1476 board, take a moment to make sure that the following items have been included inside the AR-B1476 package. This user’s guide...
Parallel Port 2.1 DMA CONTROLLER The equivalent of two 8237A DMA controllers are implemented in the AR-B1476 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 speeding information transfer with less CPU intervention.
AR-B1476 User’s Guide 2.3 INTERRUPT CONTROLLER The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1476 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.
2.4 REAL-TIME CLOCK AND NON-VOLATILE RAM The AR-B1476 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.
AR-B1476 User’s Guide 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.
