User’s Manual —M68EML08EY Emulation Module
Section 1. General Information
1.1 Introduction
This user’s manual explains connection and configuration of the Motorola
M68EML08EY Emulator Module (EML08EY). The EML08EY makes
possible emulation and debugging of target systems based on an
MC68HC908EY16 or MC68HC908EY8 microcontroller unit (MCU).
The EML08EY can be part of two development systems. This section
describes those systems and explains the layout of the EML08EY.
1.2 Development Systems
Your EML08EY can be part of two Motorola HC08 processor family
development systems: the MMDS0508 Motorola Modular Development
System (MMDS) or the MMEVS0508 Evaluation System (MMEVS). Refer to
the specific development system user’s manual for more information.
1.2.1 Motorola Modular Development System (MMDS0508)
The MMDS is an emulator system that provides a bus state analyzer and
real-time memory windows for designing and debugging a target system. A
complete MMDS consists of:
•a station module —the metal MMDS enclosure, containing the
platform board and the internal power supply. Most system cables
connect to the MMDS station module.
•an emulator module (EM) —such as the EML08EY, a separately-
purchased printed circuit board that enables system functionality for a
specific set of MCUs. The EM fits into the station module through a
removable panel in the enclosure top. The EM has connectors for a target
cable and for cables to a logic analyzer. The cable runs to an optional
target system through an aperture in the station-module enclosure, to
connect directly to the emulator module.

M68EML08EY Emulation Module - Version 1.0 User’s Manual
12 General Information MOTOROLA
General Information
•two logic clip cable assemblies —twisted-pair cables that connect the
station module to your target system, a test fixture, 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 and may be attached to
the female probe tips.
•a 9-lead RS-232 serial cable —the cable that connects the MMDS to
the host computer RS-232 port.
•system software —development software, on CD-ROM.
•MMDS0508 documentation —an MMDS operations manual
(MMDS0508OM/D) and the appropriate EM user’s manual.
You select the MMDS baud rate: 1200, 2400, 4800, 9600, 19200, 38400, or
57600.
Substituting a different EM enables your MMDS to emulate target systems
based on different MCUs or MCU families. (Your Motorola representative can
explain all the EMs available.)
1.2.2 Motorola Modular Evaluation System (MMEVS0508)
An MMEVS is an economical tool for designing, debugging, and evaluating
target systems. A complete MMEVS consists of:
•a platform board (PFB) —the bottom board, which supports the
emulator module. The platform board has connectors for power and the
the terminal or host computer.
•an emulator module (EM) —such as the EML08EY, a separately
purchased printed circuit board that enables system functionality for a
specific set of MCUs. The EM fits onto the PFB. The EM has connectors
for the target cable and for cables to a logic analyzer.
•a 9-to-25-pin adapter —a molded assembly that lets you connect the
9-pin cable to a 25-pin serial port.
•a 9-lead RS-232 serial cable —the cable that connects the station
module to the host computer RS-232 port.
•system software —development software, on CD-ROM.

An MMEVS features automatic baud rate selection: 2400, 4800, 9600, 19200,
38400, or 57600.
Substituting a different EM enables your MMEVS to emulate target systems
based on different MCUs or MCU families. (Your Motorola representative can
explain all the EMs available.).
1.3 System Requirements
An IBM PCor compatible running Windows98,Windows 2000, or Windows
NT(version 4.0) with at least 32MB of RAM and an RS-232 serial port.
1.4 EM Layout
Figure 1-1 shows the layout of the EML08EY. Jumper header W2 specifies the
operating voltage. Jumper header W4 specifies the clock signal source. Jumper
header W1 controls unification of analog ground references. Jumper header
W3 specifies the MCU to be emulated.
Target interface connectors J2 and J3 connect the EML08EY to a target
system, via the included target cable assembly. If you use your EML08EY as
part of an MMDS, run the target cable assembly through the slit in the station
module enclosure.
Connectors J1 and J5 connect to a logic analyzer. Connector J4 is the source
for an inverted clock signal. DIN connectors P1 and P2, on the bottom of the
board connect the EML08EY to the platform board. The emulation MCU is at
location U2. Connector J6 is for EM board design and factory use only.

1.6 Target Cable Assemblies
To connect your EML08EY to a target system, you need the included target
cable and adapters. See Figure 1-2.
The cable assembly for a 32-pin thin quad flat pack (QFP) package consists of:
a flex cable, a target head adapter, a socket-saver and a QFP surface mount
adapter. One end of the target cable plugs onto EML08EY connectors J2 and
J3. The other end of the flex cable plugs onto the target head adapter, which
plugs onto the QFP surface mount adapter. You should solder the QFP surface
mount adapter directly onto the target-system board in place of the MCU. The
socket-saver goes between the target head adapter and surface mount adapter.
If you use it, it will reduce wear on the target head adapter. After many
insertions, you can replace the socket-saver without replacing the entire target
head adapter.
Table 1-2 lists target cable and head part numbers appropriate for the
EML08EY.
