以太网接口
Intel 82596CA LAN控制器用于实现以太网
收发器接口。82596CA使用DMA访问本地RAM
执行其正常功能的操作。因为82596CA的
内部缓冲区和VMEbus具有未定义的等待时间段，缓冲区
如果DMA被编程为访问VMEbus，则可能发生超限。
因此，82596CA不应编程为访问VMEbus。
为每个MVME162分配一个以太网站地址。地址是
$08003E2xxxxx，其中xxxxx是分配给
电路板（即，每个MVME162具有不同的xxxxx值）。
每个MVME162都有一个显示在标签上的以太网站地址
到背板连接器P2。此外，包括以太网在内的六个字节
站地址存储在BBRAM配置区域中。即，
08003E2xxxxx存储在BBRAM中。在地址$FFFC1F2C处
可以读取四个字节（08003E2x）。在地址$FFFC1F30处，较低的两个
可以读取字节（xxxx）。请参阅BBRAM/TOD时钟存储器映射
第3章中的说明。MVME162调试器能够
检索或设置以太网站点地址。

SCSI接口
MVME162通过工业标准SCSI总线支持大容量存储子系统。这些子系统可能包括硬盘和软盘
驱动器、流式磁带驱动器和其他大容量存储设备。SCSI
接口使用NCR 53C710 SCSI I/O控制器实现。

these are accessible from the front panel. Refer to the IPIC Programming
Model in the MVME162 Embedded Controller Programmer’s Reference Guide for
details of the IP interface. Refer to the MVME162 Embedded Controller Support
Information manual for the pin assignments of the IP connectors.
Ethernet Interface
The Intel 82596CA LAN controller is used to implement the Ethernet
transceiver interface. The 82596CA accesses local RAM using DMA
operations to perform its normal functions. Because the 82596CA has small
internal buffers and the VMEbus has an undefined latency period, buffer
overrun may occur if the DMA is programmed to access the VMEbus.
Therefore, the 82596CA should not be programmed to access the VMEbus.
Every MVME162 is assigned an Ethernet station address. The address is
$08003E2xxxxx, where xxxxx is the unique 5-nibble number assigned to the
board (i.e., every MVME162 has a different value for xxxxx).
Each MVME162 has an Ethernet station address displayed on a label attached
to backplane connector P2. In addition, the six bytes including the Ethernet
station address are stored in the BBRAM configuration area. That is,
08003E2xxxxx is stored in the BBRAM. At an address of $FFFC1F2C, the upper
four bytes (08003E2x) can be read. At an address of $FFFC1F30, the lower two
bytes (xxxx) can be read. Refer to the BBRAM/TOD Clock memory map
description in Chapter 3. The MVME162 debugger has the capability to
retrieve or set the Ethernet station address.

If the data in the BBRAM is lost, use the number on the label on backplane
connector P2 to restore it.
The Ethernet transceiver interface is located on the MVME162 main module.
An industry-standard DB15 connector is located on the MVME712 series
transition module.
The MCchip provides support functions for the 82596CA. Refer to the
82596CA user’s guide and to the MVME162 Embedded Controller Programmer’s
Reference Guide for detailed programming information. Refer to the
MVME712-12, MVME712-13, MVME712A, MVME712AM, and MVME712B
Transition Modules and LCP2 Adapter Board User’s Manual or the MVME712M
Transition Module and P2 Adapter Board User’s Manual for the pin assignments
of the transition module Ethernet connectors.
SCSI Interface
The MVME162 supports mass storage subsystems through the industrystandard SCSI bus. These subsystems may include hard and floppy disk
drives, streaming tape drives, and other mass storage devices. The SCSI
interface is implemented using the NCR 53C710 SCSI I/O controller.
Support functions for the NCR 53C710 are provided by the MCchip. Refer to
the NCR 53C710 user’s guide and to the MVME162 Embedded Controller
Programmer’s Reference Guide for detailed programming information. Refer to
the MVME712-12, MVME712-13, MVME712A, MVME712AM, and
MVME712B Transition Modules and LCP2 Adapter Board User’s Manual or to the
MVME712M Transition Module and P2 Adapter Board User’s M
