如果NVRAM中的数据丢失，请使用PMC中标签上的数字连接器禁止区域恢复。对于过渡模块AUI或10BaseT/100BaseTX连接器，有关详细信息，请参阅用户手册MVME712M或MVME761。参考BBRAM/TOD时钟存储器MVME2600/2700系列单板机中的地图描述详细编程信息的程序员参考指南。
KUC321AE励磁模块PCI夹层接口MVME2700系列的一个关键特性是PCI（外围组件互连）总线。除了车载本地总线设备（SCSI、，PCI总线支持行业标准夹层接口，IEEE P1386.1 PMC（PCI夹层卡）。PMC模块为通过FDDI（光纤分布式数据接口）、ATM（异步传输）模式）、图形、以太网或SCSI端口。基板支持PMC前面板和后P2输入/输出。还提供堆叠PMC的功能基板上的承载板用于额外扩展。MVME2700支持一个PMC插槽。上的四个64针接头基板（J11、J12、J13和J14）与32位IEEE P1386.1的接口PMC兼容夹层，可添加任何所需功能。PCI
夹层卡插槽具有以下特点：PMC载体板连接器（J4）是114针Mictor连接器。请参阅第4章连接器引脚分配，了解PMC连接器。有关详细的编程信息，请参阅MVME2600/2700系列编程器中的PCI总线描述您使用的PMC模块的参考指南和用户文档打算使用。
VMEbus接口VMEbus接口由CA91C142的Universe II实现ASIC。Universe芯片将32/64位PCI本地总线连接到VMEbus。Universe II ASIC提供：
❏ PCI总线到VMEbus接口❏ VMEbus到PCI总线接口
❏ 本地VMEbus的DMA控制器功能Universe II芯片包括Universe控制和状态寄存器（UCSR）用于处理器间通信。它可以提供VMEbus系统控制器也起作用。用于详细编程信息，请参阅《Universe II用户手册》和讨论在MVME2600/2700系列程序员参考指南中。
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.
