1–5MMDS0508 Target Interface

General Description

1.1 Introduction

The M68MMDS05/08 Motorola Modular Development System (MMDS) is a tool for

developing embedded systems based on an MC68HC05 or MC68HC08

microcontroller unit (MCU). A modular emulation system, the MMDS provides

interactive control of a microcontroller application when connected to your target

system.

The MMDS environment allows for source-level debugging and simplifies writing

and debugging code. These features significantly reduce development time.

A complete MMDS includes a station module, an emulation module (EM), and a

target cable assembly. The EM completes MMDS functionality for a particular MCU

or MCU family.

1.2 MMDS Features

MMDS features include:

• Real-time, non-intrusive, in-circuit emulation

• Real-time bus state analysis

• MC68HC11K1 system controller, for fast command transfer

• Compliance with ECC92 European electromagnetic compatibility standards

• Four complex data breakpoints, each qualified by an address, an address range,

data, or externally connected logic clips.

• 32 variables or real-time variables, plus a 32-byte block of real-time memory,

mappable anywhere within a 1-kilobyte window over the 64-kilobyte HC05/HC08

memory map.

•64 kilobytes of emulation memory, to accommodate the largest available ROM

size of current HC05/HC08 MCUs.

General Description

System Components

1–6 MMDS0508 Target Interface

• 64 hardware instruction breakpoints over the 64-kilobyte memory map

• A personality file for each EM. (Each personality file defines a memory-map.)

• Latch-up resistant design (47-Ωseries resistor on I/O connections to the target

system) to make power-up sequencing unimportant.

• Built-in bus state analyzer that includes:

• 8K x 64 real-time trace buffer

– Four hardware triggers, for controlling real-time bus analysis and to

provide breakpoints

– Nine triggering modes

– Display of real-time trace data as raw data, disassembled instructions, raw

data and disassembled instructions, or assembly-language source code

– As many as 8190 pre- or post-trigger points

– Trace buffer that can be filled as you single-stepping through user software

– 16-bit time tag, or an optional 24-bit time tag that sacrifices eight logic

clips

– Eight software selections for the time tag clock source, permitting wide

time variance between analyzer events

– 16 general-purpose logic clips, five of which can be used to trigger the bus

state analyzer sequencer

• Four software-selectable internally generated oscillator clock sources

• Built-in power supply with 85 to 264 VAC input

• RS-232 operation speeds as high as 57600 baud

• Compact size: 15.38 inches (390.6 mm) deep, 10.19 inches (258.83 mm) wide, and

2.75 inches (69.85 mm) high. The station module weighs 6.0 pounds (2.72 kg).

For connection instructions, configuration instructions, and other related information,

see the installation section of this hardware addendum. For similar information with

regard to EMs, see the corresponding EM user's manual.

1.3 System Components

The MMDS components include:

•Station module: the MMDS enclosure, containing the platform board and the

internal power supply. The access panel in the enclosure top lets you insert an EM

easily.

System Components

1–7MMDS0508 Target Interface

•9-lead RS-232 serial cable: the cable that connects the station module to the host-

computer RS-232 port.

•Serial adapter: a DB9M-to-DB25F RS-232 adapter, for use with a 25-pin host-

computer serial port.

•Two logic clip cable assemblies: twisted-pair cables that connect the station

module to your target system, a test fixture, a clock, an oscillator, or any other

circuitry useful for evaluation or analysis. One end of each cable assembly has a

molded connector, which fits into the pod A or pod B connector of the station

module. Leads at the other end of each cable terminate in female probe tips. Ball

clips come with the cables.

Separately purchased components are:

•Emulation module (EM): a printed circuit board that completes MMDS

functionality for one or more MCUs. The two DIN connectors on the bottom of the

EM fit into connectors on the top of the MMDS0508 platform board, providing

power and signal connections. The EM also has a connector for the target cable.

Each EM comes with its own user’s manual.

•Target cable: a flat, flexible cable that connects the MMDS to the target system.

The cable’s emulator terminator mates to the EM target connectors; the cable’s

head terminator mates to a target head adapter. (A target cable and target head

adapter make up a target cable assembly.)

•Target head adapter: a target-cable adapter that plugs into the MCU socket of the

target system. (For some EMs, the target head adapter plugs into a surface-mount

adapter.)

Installation

2.1 Introduction

Complete MMDS installation consists of:

• Configuring the platform board,

• Configuring the emulation module (EM),

• Installing the EM, and

• Making system cable connections.

This section explains all items except EM configuration. (As EM configuration is

specific to each EM, you must follow the instructions of your EM user's manual.)

Additionally, this sections explains how to remove an EM from the station module.

Figure 2.1 shows the right side of the MMDS station module, with the access panel

open. Callouts indicate the reset switch and power LED (on the front of the station

module), and the logic cable A and B connectors (on the right side of the station

module). (Alternate names for the logic cable connectors are pod A and pod B.) If you

use logic clip cables, always attach the black clip to ground.

Figure 2.2 shows the left side of the station module, with the access panel closed.

Callouts indicate the power cord socket, the power switch, and the 9-pin RS-232 serial

connector. The circular, +5 V out connector is reserved for possible future features. (A

spacer covers the final enclosure cutout, for a future connector.)
