用MPC107 PCI桥控制器的局部总线从属性能设计高性能P

The MPC106 and the MPC107 provide support for an interface method called local-bus slave (LBS) that allows devices to be more easily attached to the high-speed 60x bus. The LBS can respond to read and write cycles, while relying upon the MPC107 to provide the majority of the interface controls. An LBS device monitors a subset of the 60x bus, and assert TA when the read or write operation has been completed. A device that provides local-bus slave I/O and memory access is outlined in the remaining sections of this application note, and is referred to as the AEIOU (Applications Engineering Input/Output Unit). For the
remainder of this document, the MPC107 is used to refer to either the MPC107 or the MPC106; the information contained herein applies to both devices unless otherwise stated.
