Preface
This document provides general information, hardware preparation and installation
instructions, operating instructions, and a functional description for the MVME197LE
Single Board Computer.
This document is intended for anyone who wants to design OEM systems, supply
additional capability to an existing compatible system, or work in a lab environment
for experimental purposes.
A basic knowledge of computers and digital logic is assumed.
To use this document, you may wish to become familiar with the publications listed in
the Related Documentation section found in the following pages.
Document Terminology
Throughout this document, a convention has been maintained whereby data and
address parameters are preceded by acharacter whichspecifies the numeric format, as
follows:
For example, “12” is the decimal number twelve, and “$12” is the decimal number
eighteen. Unless otherwise specified, all address references are in hexadecimal
throughout this document.
An asterisk (*) following the signal name for signals which are level significant denotes
that the signal is true or valid when the signal is low.
An asterisk (*) following the signal name for signals which are edge significant denotes
that the actions initiated by that signal occur on high to low transition.
In this document, assertion and negation are used to specify forcing a signal to a
particular state. In particular, assertion and assert refer to a signal that is active or true;
negation and negate indicate a signal that is inactive or false. These terms are used
independently of the voltage level (high or low) that they represent.
$ dollar specifies a hexadecimal number
% percent specifies a binary number
& ampersand specifies a decimal number

Data and address sizes are defined as follows:
❏A byte is eight bits, numbered 0 through 7, with bit 0 being the least
significant.
❏A two-byte is 16 bits, numbered 0 through 15, with bit 0 being the least
significant. For the MVME197series and other RISC modules, this is called
a half-word.
❏A four-byte is 32 bits, numbered 0 through 31, with bit 0 being the least
significant. For theMVME197 series and other RISC modules, this iscalled
a word.
❏An eight-byte is 64 bits, numbered 0 through 63, with bit 0 being the least
significant. For theMVME197 series and other RISC modules, this iscalled
a double-word.
Throughout this document, it is assumed that the MPU on the MVME197 module
series is always programmed with big-endian byte ordering, as shown below. Any
attempt to use small-endian byte ordering will immediately render the MVME197Bug
debugger unusable.
The terms control bit and status bit are used extensively in this document. The term
control bit is used to describe a bit in a register that can be set and cleared under
software control. The term true is used to indicate that a bit is in the state that enables
the function it controls. The term false is used to indicate that the bit is in the state that
disables the function it controls. In all tables, the terms 0 and 1 are used to describe the
actual value that should be written to the bit, or the value that it yields when read. The
term status bit is used to describe a bit ina register thatreflects a specific condition. The
status bit can be read by software to determine operational or exception conditions.

GENERAL INFORMATION
Introduction
This user’s manual provides general information, preparation for use and
installation instructions, operating instructions, and a functional description
for the MVME197LE version of the MVME197 series of single board
computers.
General Description
The MVME197LE module is a double-high VMEmodule based on the
MC88110 RISC microprocessor. The MVME197LE has 32/64MB of DRAM,
1MB of FLASH memory, 8KB of static RAM (with battery backup), a time of
day clock (with battery backup), an Ethernet transceiver interface, four serial
ports with EIA-232-D interface, six tick timers, a watchdog timer, 128/256KB
of BOOT ROM, a SCSI bus interface with DMA (Direct Memory Access), a
Centronics printer port, an A16/A24/A32/D8/D16/D32 VMEbus
master/slave interface, and a VMEbus system controller.
Input/Output (I/O) signals are routed through the MVME197LE’s backplane
connector P2. A P2 Adapter Board or LCP2 Adapter board routes the signals
and grounds from connectorP2 to an MVME712 series transition module. The
MVME197LE supports the MVME712M, MVME712A, MVME712AM, and
MVME712B transition boards (referred to here as the MVME712X, unless
separately specified). The MVME197LE also supports the MVME712-12 and
MVME712-13 (referred to as the MVME712-XX, unless separately specified).
These transitionboards provide configurationheaders, serial port drivers, and
industry standard connectors for the I/O devices.
The MVME197LE modules have eight ASICs (Application-Specific Integrated
Circuits) described in the following order: BusSwitch, DCAM, ECDM, PCC2,
and VME2.
The BusSwitch ASIC provides an interface between the processor bus
(MC88110 bus) and the local peripheral bus (MC68040 compatible bus). Refer
to the MVME197LE block diagram (Figure 1-1). It provides bus arbitration for
the MC88110 bus and serves as a seven level interrupt handler. It has
programmable map decoders for both busses, as well as write post buffers on
each, two tick timers, and four 32-bit general purpose registers.

General Information
1-2 User’s Manual
1
Note For the MVME197 series, the term Local Bus, as used in
other MVME1xx Single Board Computer series, is referred
to as the Local Peripheral Bus.
The DCAM (DRAM Controller and Address Multiplexer) ASIC provides the
address multiplexers and RAS/CAS/WRITE control for the DRAM as well as
data control for the ECDM.
The ECDM (Error Correction and Data Multiplexer) ASIC multiplexes
between four data paths on the DRAM array. Since the device handles 16 bits,
four such devices are required onthe MVME197LE to accommodate the 64-bit
data bus of the MC88110 microprocessor. Single-bit error correction and
double-bit detection is performed in the ECDM.
The PCCchip2 (Peripheral Channel Controller) ASIC provides two tick timers
and the interface to the LAN chip, the SCSI chip, the serial port chip, the
printer port, and the BBRAM (Battery Backup RAM).
The VMEchip2 ASIC provides a VMEbus interface. The VMEchip2 includes
twotick timers, a watchdogtimer,programmablemapdecodersfor the master
and slave interfaces, and a VMEbus to/from the local peripheral bus DMA
controller, a VMEbus to/from the local peripheral bus non-DMA
programmed access interface, a VMEbus interrupter, a VMEbus system
controller, a VMEbus interrupt handler, and a VMEbus requester.
Local peripheral bus to VMEbus transfers can be D8, D16, or D32. VMEchip2
DMA transfers to the VMEbus, however, can be 64 bits wide as Block Transfer
(BLT).

Cooling Requirements
The Motorola MVME197LE VMEmodule is specified, designed, and tested to
operate reliably with an incoming air temperature range from 0° to 55° C (32°
to 131° F) with forced air cooling at a velocity typically achievable by using a
100 CFM axial fan. Temperature qualification is performed in a standard
Motorola VMEsystem 3000 chassis. Twenty-five watt load boards are inserted
in two card slots, one on each side, adjacent to the board under test, to simulate
a high power density system configuration. An assembly of three axial fans,
rated at 100 CFM per fan, is placed directly under the VME card cage. The
incoming air temperature is measured between the fan assembly and the card
cage, where the incoming airstream first encounters the module under test.
Test software is executed as the module is subjected to ambient temperature
variations. Case temperatures of critical, high power density integrated
circuits are monitored to ensure component vendors specifications are not
exceeded.

While the exact amount of airflow required for cooling depends on the
ambient air temperature and the type, number, and location of boards and
other heat sources, adequate cooling can usually be achieved with 10 CFM and
490 LFM flowing over the module. Less airflow is required to cool the module
in environments having lower maximum ambients. Under more favorable
thermal conditions, it may be possible to operate the module reliably at higher
than 55° C with increased airflow. It is important to note that there are several
factors, in addition to the rated CFM of the air mover, which determine the
actual volume and speed of air flowing over a module.
FCC Compliance
The MVME197LE was tested in an FCC-compliant chassis, and meets the
requirements for Class A equipment. FCC compliance was achieved under the
following conditions:
1. Shielded cables on all external I/O ports.
2. Cable shields are connected to earth ground via metal shell connectors
bonded to a conductive module front panel.
3. Conductivechassisrailsconnected to earthground.Thisprovidesthepath
for connecting shields to earth ground.
4. All chassis and MVME197LE front panel attachment screws are properly
tightened.
For minimum RF emissions, it is essential that the conditions above be
implemented; failure to do so could compromise the FCC compliance of the
equipment containing the module.
Equipment Required
The following equipment is required to make a complete system using the
MVME197LE:
System console terminal
Disk drives and controllers
MVME712 series transition modules (MVME712-12, MVME712-13,
MVME712A, MVME712AM, MVME712B, or MVME712M); P2 or LCP2
Adapter Boards
Operating system
The MVME197Bug debug monitor firmware (197Bug) is provided in the
FLASH memory on the MVME197LE module. It provides over 50 debug,
up/down line load, and disk bootstrap load commands, as well as a set of
onboard diagnostics and a one-line assembler/disassembler. 197Bug includes
