IndustryPack (IP) Interfaces
The IPIC ASIC on the MVME162 supports four IndustryPack (IP) interfaces;
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.
