MC143421

PCI BUS PERIPHERAL INTERFACE BUS (PIB) MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information PCI Bus Interface The MC143421 PCI Bus Interface chip is a low cost and highly integrated PCI interface solution that includes Advanced Configuration Power Interface (ACPI) features. It is designed to enable the addition of a PCI interface to PC peripherals such as DSP–based analog modems. The Peripheral Interface Bus (PIB) that interfaces this device to the PC peripheral function provides four address lines, byte–wide data, and eight programmable lines that can be used for chip selects, interrupts, and power–down enable.
