摘要：本应用笔记中包含必要的信息接口1非复用总线处理器下面的DallasSemiconductor的T1或E1的成帧器和单芯片收发器（SCT的）：DS2141A，DS2143，DS2151，或DS2153。这些设备的最初设计到接口的处理器，使用复用总线配置。一些额外的外部逻辑和软件的细微变化，任何非复用的处理器可以连接到这些设备。设计者的显而易见的好处是更广泛的处理器，这将是能够与这些设备接口。本应用笔记中包含图表说明如何连接复用的地址和数据总线的处理器独立的地址和数据总线。它包含必要的达拉斯半导体总线时序图。最后，有关于如何编写软件的信息，这将使总线接口读写达拉斯半导体器件。我们的目标是给设计师与设备进行通信的硬件和软件的所有必要的信息。Maxim>AppNotes>COMMUNICATIONSCIRCUITSTELECOMKeywords:DS2141A,DS2143,DS2151,DS2153,interface,parallel,multiplex,nonmultiplex,bus,processorMay31,2001APPLICATIONNOTE326DS2141A,DS2143,DS2151,DS2153InterfacingtoaNonmultiplexedBusAbstract:ThisapplicationnotecontainsinformationnecessarytointerfaceanonmultiplexedbusprocessortothefollowingDallasSemiconductorT1orE1framersandsinglechiptransceivers(SCTs):DS2141A,DS2143,DS2151,ortheDS2153.Thesedeviceswereoriginallydesignedtointerfacewithaprocessorthatusesamultiplexedbusconfiguration.Withsomeadditionalexternallogicandminorchangestothesoftware,anynonmultiplexedprocessorcanbeconnectedtothesedevices.Theobviousbenefittothedesigneristhew……
