GENERAL DESCRIPTION
he ELANC-PCI (Twisted-pair Ether-LAN Controller with PCI Interface) integrates a W89C902 Serial(ELANCPCI) LAN Coprocessor for Twisted-Pair (SLCT) and PC/AT PCI bus interface logic into a single chip. The ELANC-PCI provides an easy way of implementing the interface between an IEEE 802.3-compatible Ethernet and a personal computer, ELANC-PCI also provide fast DMA operation to improve the packet transmit and receive performance. The PCI bus is a high performance local bus architecture with low latency random access time. It is a synchronous bus with operation up to 33MHz. The PCI bus interface is designed to provide the registers with the device information required for configuration, recording the status of the lines , control registers, interrupt line and I/O base address registers. It is capable of functioning in a half-duplex environment. The W89C940Fis designed to fully comply with the standard of PCI 2.0 specification. Taking advantage of PCI's nature, W89C940F supports auto-configuration function to free users' depression and confusion on tunning system resources conflict.
