如果NVRAM中的數(shù)據(jù)丟失，請使用PMC中標簽上的數(shù)字連接器禁止區(qū)域恢復。對于過渡模塊AUI或10BaseT/100BaseTX連接器，有關詳細信息，請參閱用戶手冊MVME712M或MVME761。參考BBRAM/TOD時鐘存儲器MVME2600/2700系列單板機中的地圖描述詳細編程信息的程序員參考指南。
KUC321AE勵磁模塊PCI夾層接口MVME2700系列的一個關鍵特性是PCI（外圍組件互連）總線。除了車載本地總線設備（SCSI、，PCI總線支持行業(yè)標準夾層接口，IEEE P1386.1 PMC（PCI夾層卡）。PMC模塊為通過FDDI（光纖分布式數(shù)據(jù)接口）、ATM（異步傳輸）模式）、圖形、以太網(wǎng)或SCSI端口?；逯С諴MC前面板和后P2輸入/輸出。還提供堆疊PMC的功能基板上的承載板用于額外擴展。MVME2700支持一個PMC插槽。上的四個64針接頭基板（J11、J12、J13和J14）與32位IEEE P1386.1的接口PMC兼容夾層，可添加任何所需功能。PCI
夾層卡插槽具有以下特點：PMC載體板連接器（J4）是114針Mictor連接器。請參閱第4章連接器引腳分配，了解PMC連接器。有關詳細的編程信息，請參閱MVME2600/2700系列編程器中的PCI總線描述您使用的PMC模塊的參考指南和用戶文檔打算使用。
VMEbus接口VMEbus接口由CA91C142的Universe II實現(xiàn)ASIC。Universe芯片將32/64位PCI本地總線連接到VMEbus。Universe II ASIC提供：
? PCI總線到VMEbus接口? VMEbus到PCI總線接口
? 本地VMEbus的DMA控制器功能Universe II芯片包括Universe控制和狀態(tài)寄存器（UCSR）用于處理器間通信。它可以提供VMEbus系統(tǒng)控制器也起作用。用于詳細編程信息，請參閱《Universe II用戶手冊》和討論在MVME2600/2700系列程序員參考指南中。
If the data in NVRAM is lost, use the number on the label in the PMC
connector keepout area to restore it.
For the pin assignments of the transition module AUI or
10BaseT/100BaseTX connector, refer to the user’s manual for the
MVME712M or MVME761. Refer to the BBRAM/TOD Clock memory
map description in the MVME2600/2700 Series Single Board Computer
Programmer’s Reference Guide for detailed programming information.
PCI Mezzanine Interface
A key feature of the MVME2700 family is the PCI (Peripheral Component
Interconnect) bus. In addition to the on-board local bus devices (SCSI,
Ethernet, graphics, etc.), the PCI bus supports an industry-standard
mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card).
PMC modules offer a variety of possibilities for I/O expansion through
FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer
Mode), graphics, Ethernet, or SCSI ports. The base board supports PMC
front panel and rear P2 I/O. There is also provision for stacking a PMC
carrier board on the base board for additional expansion.The MVME2700 supports one PMC slot. Four 64-pin connectors on the
base board (J11, J12, J13, and J14) interface with 32-bit IEEE P1386.1
PMC-compatible mezzanines to add any desirable function. The PCI
Mezzanine Card slot has the following characteristics:
The PMC carrier board connector (J4) is a 114-pin Mictor connector.
Refer to Chapter 4, Connector Pin Assignments for the pin assignments of
the PMC connectors. For detailed programming information, refer to the
PCI bus descriptions in the MVME2600/2700 Series Programmer’s
Reference Guide and to the user documentation for the PMC modules you
intend to use.
VMEbus Interface
The VMEbus interface is implemented with the CA91C142 ‘Universe II
ASIC. The Universe chip interfaces the 32/64-bit PCI local bus to the
VMEbus. The Universe II ASIC provides:
? The PCI-bus-to-VMEbus interface
? The VMEbus-to-PCI-bus interface
? The DMA controller functions of the local VMEbus
The Universe II chip includes Universe Control and Status Registers
(UCSRs) for interprocessor communications. It can provide the VMEbus
system controller functions as well. For detailed programming
information, refer to the Universe II User’s Manual and to the discussions
in the MVME2600/2700 Series Programmer's Reference Guide.
