Motorola MVME162PA-344E Embedded Controller

Manual Terminology

Throughout this manual, a convention is used which precedes data and

address parameters by a character identifying the numeric format as follows:

dollar

% percent

specifies a hexadecimal character

specifies a binary number

& ampersand specifies a decimal number

Unless otherwise specified, all address references are in hexadecimal.

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 manual, 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.

In this manual, MVME712 series transition module refers generically to the

MVME712-12. MVME712-13. MVME712A, MVME712AM, or MVME712M.

MVME712x transition module refers to the closely related MVME712-12.

MVME712-13. MVME712A, or MVME712AM (not to the MVME712M).

References to a specific module use the complete designation of that module.

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 word is 16 bits, numbered 0 through 15. with bit 0 being the least

significant.

A longword is 32 bits, numbered 0 through 31. with bit 0 being the least

significant

Introduction

This chapter provides unpacking instructions, hardware preparation

guidelines, and installation instructions for the MVME162 Embedded

Controller.  Hardware preparation for the MVME712 series transition

modules is described in separate manuals; refer to the Related Documentation

section in Chapter 1

Hardware Preparation

To produce the desired configuration and ensure proper operation of the

MVME162. you may need to carry out certain modifications before installing

the module.

The MVME162 provides software control over most options: by setting bits in

control registers after installing the MVME162 in a system, you can modify its

configuration. (The MVME162 registers are described in Chapter 4. and/or in

the MVME162 Embedded Controller Programmer’s Reference Guide as listed in

Related Documentation in Chapter 1.)

Some options, however, are not software-programmable. Such options are

controlled by manual installation or removal of header jumpers or interface

modules.

Figure 2-1 illustrates the placement of the switches, jumper headers,

connectors, and LED indicators on the MVME162. Manually configurable

items include:

SIM selection for serial port B configuration (J10)

System controller selection (J1)

Synchronous clock selection (J11) for Serial Port 1/Console

Synchronous clock selection (J12) for Serial Port 2

SRAM backup power source selection (J20)

EPROM size selection (J21)

General-purpose readable register configuration (J22)

The MVME162 has been factory tested and is shipped with the configurations

described in the following sections.  The MVME162’s required and factory

installed Debug Monitor, MVME162Bug (162Bug), operates with those factory

settings.

SIM Selection

Port B of the MVME162’s Z85230 serial communications controller is

configurable via a serial interface module (SIM) which is installed at connector

J10 on the MVME162 board.  Four serial interface modules are available:

EIA-232-D (DCE and DTE)

EIA-530 (DCE and DTE)

You can change Port B from an EIA-232-D to an EIA-530 interface (or vice

versa) by mounting the appropriate serial interface module. Port B is routed

(via the SIM at J10) to the 25-pin DB25 front panel connector marked SERIAL

PORT 2.

For the location of SIM connector J10 on the MVME162. refer to Figure 2-1.

Figure 2-2 illustrates the secondary side (bottom) of a serial interface module,

showing the J1 connector which plugs into SIM connector J10 on the

MVME162. Figure 2-3 (sheets 3-6), Figure 2-4 (sheets 3-4), and Figure 2-5

illustrate the configurations available for Port B.

For the part numbers of the serial interface modules, refer to Table 2-1. The

part numbers are ordinarily printed on the primary side (top) of the SIMs, but

may be found on the secondary side in some versions.

If you need to replace an existing serial interface module with a SIM of another

type, go to Removal of Existing SIM below. If there is no SIM on the main board,

skip to Installation of New SIM
