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.

• 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 hostcomputer 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.)

2.2 Configuring the Platform Board
The MMDS platform board has four jumper headers, all located near the front. Jumper
header J1 is for factory test. Jumper headers J2, J3, and J4 control the voltage levels
for ports A through D.
NOTE
2.2.1 Factory Test Header (J1)
Before shipping the MMDS, factory personnel configure the
platform board correctly for virtually all users. You should not
reconfigure platform-board headers unless your EM user’s manual
tells you to.
The diagram in Figure 2.3 shows the factory configuration of jumper header J1. The
jumper between pins 1 and 2 is correct for MMDS operation.

Figure 2.3 Factory Test Header (J1)
(Ignore the alternate jumper position, which is reserved for factory tests.)
2.2.2 Port Voltage Control Headers (J2–J4)
Jumper headers J2 through J4, near the right front corner of the platform board, set the
voltage levels for ports A through D. Header J2 is the port A control; header J3 is the
port B control; header J4 is the control for port C or D (whichever pertains to your
EM).
The diagram Figure 2.4 shows the factory configuration. The jumpers between pins 1
and 2 of these headers set the +5-volt level for all ports. This is the correct
configuration for MMDS operation, unless your EM user's manual says that your EM
is a low-voltage board.
Figure 2.4 Port Voltage Control Headers (J2–J4)
If your EM can operate at low voltage, you can configure any of the ports for the lowvoltage level. To do so, reposition the corresponding header’s jumper to pins 2 and 3.

Installing the EM
2.3 Installing the EM
CAUTION Be sure to turn off power to the MMDS when you install or remove
an EM. This prevents power surges that could damage MMDS
circuits.
Follow these steps to install an EM in the MMDS enclosure:
1. Make sure that station module power is off.
2. Unscrew (one quarter turn) the two captive screws of the access panel, then remove the
panel.
3. Install the EM on the platform board: Carefully fit the female 96-pin DIN connectors (on
the bottom of the EM) onto the corresponding male DIN connectors (on the top of the
platform board). Snap the EM onto the plastic standoffs and make sure that the DIN
connectors are joined firmly.
4. Connect the target cable, if appropriate.
5. Reposition the access panel, securing it with the screws.
NOTE
Many EM boards have 64-pin female DIN connectors. Like their 96pin counterparts, these smaller connectors also mate with the male
DIN connectors of the platform board. The connector keys ensure
proper alignment.
2.4 Removing the EM
Follow these steps to remove an EM from the MMDS enclosure:
1. Make sure that station module power is off.
2. Unscrew (one quarter turn) the two captive screws of the access panel, then remove the
panel.
3. Disconnect the target cable from the EM target connectors.
4. Unsnap all plastic standoffs from the edges of the EM.
5. Carefully lift the EM straight up, separating it from the platform board.
6. You are ready to install a different EM or to configure the platform board. When you
finish such other actions, reposition the access panel, securing it with the screws.

Making Cable Connections
2.5 Making Cable Connections
You must connect the station module to the host computer and to line power.
According to your specific application, you also may need to connect the EM to your
target system, or to connect the logic clip cable assemblies.
2.5.1 Host Computer Connection
Connect the 9-lead serial cable between the MMDS 9-pin serial connector and the
COM1 serial port connector of the host computer.
• COM1 is the default serial port. You may use a different host serial port, provided
that you use the appropriate software startup command to specify the port number.
• A 9-to-25-pin adapter came with your MMDS. If the host serial port is a 25-pin
connector, use this adapter between the port connector and the serial cable.
2.5.2 Bus State Analyzer Connection
If your work session includes bus state analysis, you may need the logic clip cable
assemblies. The two logic clip connectors, pod A and pod B, let the analyzer capture
external events. Logic clip connections also let you input external clock signals for the
emulator and analyzer.
The pod A and pod B connectors are on the right side of the station module. Pod A is
nearest the station module power supply. These pod connectors correspond to the
cable A and cable B selections available in the bus state analyzer configuration
window. The Connector Information section includes pinout information for both
logic clip connectors.
If you need only one logic cable assembly, connect it to either pod A or pod B. Orient
the cable connector so that its pin 1 connects to pin 1 of the pod, according to the
keyed plastic. Connect the other end of the logic cable assembly to an external target
point. Optionally, connect the probe tips to the ball clips that come with the cable
assembly, then connect the ball clips to appropriate external test points.
NOTE Always connect the black (ground) probe tip to an appropriate target-
system ground point before connecting other clips to target points.
The pod A white probe is the external clock input for the emulator;
the pod B white probe of pod B is the external clock input for the
analyzer.

remaining pod connector of the station module. Make target-system connections as for
the first cable.
2.5.3 Target Cable Connection
To connect the MMDS to a target system, you must use a target cable assembly: a
target cable and a target head.
Installation
Making Cable Connections
NOTE
Follow these instructions:
1. Make sure that station module power is off; make sure that power is not applied to the
target system.
2. Remove the MMDS access panel, for access to the EM.
3. The EM has one or two target connectors, on its right side. Connect the target cable’s
emulator terminal to the EM target connectors.
4. Connect the target cable’s head terminator to the appropriate target head adapter.
NOTE
5. Plug the target head adapter into the MCU socket (or surface-mount adapter) of the target
system.
6. Replace the access panel. (The target cable must run through the slit in the station-module
enclosure.)
Press only on the rigid plastic terminators of the cable. Pressing on
the flexible part of the cable can damage the cable.
The EM user’s manual should identify the target head adapter
appropriate for your target system. Make sure that the adapter and the
target cable mate correctly.
2.5.4 Power Connection
The final MMDS connection is line power. The MMDS power switch is the rocker
switch on the left side of the station module. Set the power switch to OFF.
Insert the female end of the power cord into the power cord socket. Then plug the
other end of the cord into a line-power outlet and set the power switch to ON. The
green LED on the front of the station module lights to confirm system power.

4.1 Introduction
MMDS Target Component
4.1 Introduction
An advanced feature of the debugger for the embedded systems development world is
the ability to load different target components, which implement the interface with
target systems. This document introduces the MMDS0508 Modular Development
System for the MC68HC05 and MC68HC08 MCU families.

The MMDS is a Motorola interface that the debugger uses to communicate with an
external system (also called a target system).
This chapter describes MMDS0508 features, including memory mapping and the bus
analyzer.
With this interface, you can download an executable program from the debugger
environment. The destination of this program is an external target system, based on a
Motorola MCU, that executes the program. The debugger receives feedback of real
target-system behavior.
The debugger fully supervises and monitors the target-system MCU. That is, the
debugger controls the CPU execution. You can read and write in internal or external
memory (even when the CPU is running); you can single-step, run, or stop processes
in the CPU.
NOTE
Uninvolved Components As an external MCU executes the code, the
MMDS target component cannot provide memory statistics. This
means that you cannot use the MMDS target component for
profiling, coverage analyzing, watchpoints, or I/O Simulation.

This chapter describes the specific features of the MMDS0508, including emulation
memory mapping, as well as the function and purpose of the bus analyzer. The
explanations of windows and dialog boxes are with the explanations of corresponding
MMDS0508 features.
4.2.1 MMDS0508
The MMDS0508 is an emulator system, for CPU05 or CPU08 MCUs, that provides
emulation memory and a bus state analyzer.
4.2.2 Configuration
The functions above are specific for the MMDS0508, so are available only with this
emulator component. To use these features select the corresponding menu commands
shown in Figure 4.1, such as MMDS0508 > ...

4.5 Loading the MMDS0508 Target
Usually, the PROJECT.INI file specifies the target. To make the MMDS the target,
change the file’s “Target=” line to “Target=Motosil”. The MotoSIL driver
automatically detects the MMDS. However, if the driver detects nothing, an error
message informs you that the target is not connected to the expected port.
Additionally, the Communications Device Specification dialog box appears, so that
you can set the correct baud-rate and communication-port parameter values. See the
Communication Configuration section of this document for more details.
Another way to load the MMDS0508 target is selecting Set Target... from the
Component Menu (below) as shown in Figure 4.3
list of possible targets.
