1.2 Introduction
This user’s manual explains connection, configuration, and operation
information specific to the M68EM08JB8 emulator module (JB8EM). The
JB8EM lets you emulate and debug target systems based on the
MC68HC908JB8 microcontroller unit (MCU):
This section describes Motorola’s two development systems that use the
JB8EM, and it explains the JB8EM’s layout.
1.3 Development Systems
The JB8EM can be part of two Motorola development systems:
•
MMDS0508 Motorola Modular Development System (MMDS)
•
MMEVS0508 Motorola Modular Evaluation System (MMEVS)

General Description
1.3.1 Motorola Modular Development System (MMDS)
The MMDS is an emulator system that provides a bus state analyzer and
real-time memory windows. The unit’s integrated design environment includes
an editor, an assembler, user interface, and source-level debug.
A complete MMDS consists of:
•
Station module — The metal MMDS enclosure containing the control
board and the internal power supply
•
Emulator module (EM) — A separately purchased printed circuit board
that enables system functionality for a specific set of MCUs
•
Two logic clip cable assemblies — Twisted-pair cables that connect the
station module to the 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 station-module
pod A or pod B. Leads at the other end of each cable terminate in female
probe tips. Ball clips come with the cable assemblies.
•
9-lead RS-232 serial cable — Cable that connects the station module to
the host computer RS-232 port
•
9- to 25-pin adapter — A molded assembly that connects the 9-pin cable
to a 25-pin serial port
•
System software — MCUez™ software on CD-ROM and P&E
Microcomputer System, Inc. software on CD-ROM
•
MMDS documentation — MMDS Operations Manual, Motorola
document order number MMDS0508OM/D; the MCUez software

General Description
Development Systems
MMDS baud rates are selected by the user at 2400, 4800, 9600, 19,200, 38,400,
or 57,600.
As mentioned, the JB8EM gives the MMDS the ability to emulate target
systems based on MC68HC908JB8 MCUs. By substituting a different EM,
MMDS can be enabled to emulate target systems based on a different MCU. (A
local Motorola representative can explain all the EMs available.)
1.3.2 Motorola Modular Evaluation System (MMEVS)
An MMEVS is an economical, two-board tool for designing, debugging, and
evaluating target systems based on MC68HC05 or MC68HC08 MCUs.
A complete MMEVS consists of:
•
Platform board (PFB) — The bottom board, which supports the emulator
module; has connectors for power and for a terminal or host computer
•
Emulator module (EM) — A separately purchased printed circuit board
that enables system functionality for a specific set of MCUs; fits onto
the PFB
•
RS-232 serial cable — A separately purchased cable that connects the
PFB to the host computer RS-232 port
•
System software — MCUez™ software on CD-ROM and P&E
Microcomputer System, Inc. software on CD-ROM
•
MMEVS documentation — MMEVS Operations Manual, Motorola
document order number MMEVSOM/D; the MCUez software manual,
included with the MCUez software package; a system software manual,
included with the P&E Microcomputer System, Inc.’s MMDS0508
software package; and this emulator user's manual
An MMEVS features automatic selection of the communication baud rate from
these choices: 2400, 4800, 9600, 19,200, 38,400, or 57,600.
With a JB8EM, the MMEVS emulates target systems based on
MC68HC908JB8 MCUs. By substituting a different EM, the MMEVS can be
enabled to emulate target systems based on a different MCU. (A local Motorola
representative can explain all the EMs available.)

Specifications
The main elements of the JB8EM are:
•
DIN connectors P1 and P9 — Connect the EM to the MMDS control
board or the MMEVS platform board
•
Connector P2 — Permits connection to a logic analyzer

2.2 Introduction
This section explains configuration and operation of the JB8EM when it is
installed in an MMDS (Motorola modular development system) or MMEVS
(Motorola modular evaluation system). For other parts of system installation or
configuration, see the MMDS or MMEVS hardware manuals.
NOTE:
A JB8EM already installed in an MMDS station module can be reconfigured.
To do so, switch off station-module power, then follow the guidance in this
section. Similarly, JB8EM that is already installed on the MMEVS platform
board can be reconfigured, provided that platform-board power is
disconnected.
CAUTION:
Be sure to switch off or disconnect power when reconfiguring an installed EM.
Reconfiguring EM jumper headers with the power on can damage system
circuits.

ESD CAUTION:
Ordinary amounts of static electricity from clothing or the work environment
can damage or degrade electronic devices and equipment. For example, the
electronic components installed on printed circuit boards are extremely
sensitive to electrostatic discharge (ESD). Wear a ground wrist strap whenever
handling any printed circuit board. This strap provides a conductive path for
safely discharging static electricity to ground.
2.3 Setting Jumper Headers
The JB8EM has two jumper headers. Table 2-1 contains a summary of settings
for these headers. 2.3.1 Pulldown Enable Jumper (P3) and 2.3.2 Clock
Source Header (P5) give additional information about each jumper header.

2.3.1 Pulldown Enable Jumper (P3)
Install a jumper on jumper header P3 to connect a 1MΩ resistor between D– of
MC68HC908JB8 and ground. DO NOT remove this jumper; if removed, proper
operation of the system cannot be guaranteed. Figure 2-1 shows the default
factory jumper header configuration, which has a fabricated jumper installed on

Alternately, two other clock signal sources can be selected, as shown in
Figure 2-2.
NOTE:
•
To select the clock signal from the MMDS control board or MMEVS
platform board install the fabricated jumper between pins 1 and 2. Then
use the system software to select a frequency.
•
To select the target system as the clock source, install the fabricated
jumper between pins 5 and 6. Ensure that the clock source (OSC1) is
connected to the EM through the target cable, connector P7 pin 3.
Only one jumper should be inserted on jumper header P5 at a time. Inserting
multiple jumpers in P5 might damage the JB8EM.

2.4 Remaining System Installation
When both jumper headers are configured, follow these steps to complete the
JB8EM installation:
•
To install the JB8EM in an MMDS station module, remove the entire top
half of the station-module enclosure. Fit together EM connectors P1 and
P9 (on the bottom of the board) and control-board connectors P1 and P2.
Snap the corners of the EM onto the plastic standoffs.
•
To install the JB8EM on an MMEVS platform board, fit together EM
connectors P1 and P9 (on the bottom of the board) and platform-board
connectors P3 and P4. Snap the corners of the EM onto the plastic
standoffs.
•
Copy the personality file from the provided P&E or MCUez CD-ROMs
to the directory that contains the debugging software. The personality file
for the MC68HC908JB8 MCU are:
–
00C57Vxx.MEM - MCUez personality file
–
00457Vxx.MEM - P&E personality file
At this point, make any system cable connections and restore power. For
instructions, consult the MMDS or MMEVS operations manuals.

3.5 Target Cable Assembly
To connect the JB8EM to a target system, a separately purchased target cable
assembly is needed, plus the appropriate target head and target-head/adapter
package.
Figure 3-3 shows how one end of the flex cable plugs into the JB8EM module,
and it also shows how the target head connects into the target system.
If the JB8EM is installed in the MMDS station module, run the flex cable
through the slit in the station-module enclosure.
