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.

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

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

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 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.
2.2.1 Factory Test Header (J1)
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.

(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 low-
voltage level. To do so, reposition the corresponding header’s jumper to pins 2 and 3.

Installation
Installing the EM
2–13MMDS0508 Target Interface
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 96-
pin 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.

Installation
Making Cable Connections
2–14 MMDS0508 Target Interface
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.

Installation
Making Cable Connections
2–15MMDS0508 Target Interface
If you need the second logic cable assembly, connect it in the same way to the
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.
NOTE Press only on the rigid plastic terminators of the cable. Pressing on
the flexible part of the cable can damage the cable.
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 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.
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.)
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.

Connector Information
3.1 Introduction
This section provides pin assignments and signal descriptions for connectors common
to all MMDS systems. For similar information about EM connectors, see the
corresponding EM user's manual.
Additionally, this section explains the reset switch, and fuse replacement.
3.2 Reset Switch
RS-232 handshake signals control MMDS resets. A reset initializes the control board
from its startup point. If the host serial port does not implement handshaking, you
must reset the MMDS manually.
To do so, find the reset switch, which is recessed behind the small hole in the front of
the station module. Insert a probe or stiff wire into the reset switch hole. Press gently
to trip the switch.
