Introduction
Your M68EM05P18 gives your Motorola development tool the ability to
emulate target systems based on the MC68HC805P18 and
MC68HC05P18 microcontroller units (MCUs). By substituting a different
emulationmodule(EM), you can enableyourMotorola development tool
to emulate other MCUs. Refer to
Motorola’s Development Tool Selector
Guide
, order number SG173/D, for a complete list of available EMs.
This hardware user's manual explains connection, configuration, and
operation information specific to the M68EM05P18 emulation module.
The module can be installed in any of three Motorola development
systems.ToconfigureyourM68EM05P18foruseaspartof anMMDS05
or an MMEVS05/MMEVS08, follow the instructions given in
MMDS/MMEVS Configuration and Operation on page 19. To
configure your M68EM05P18 for use as part of an HC05EVS, follow
instructions given in HC05EVS Configuration and Operation on page
31.

Emulation Module Layout
Figure 1 shows the layout of the M68EM05P18. W1 selects the
clock-signal source. Jumper header W2 controls the path of a target
reset.
Target connector J2 is the interface to a target system and uses a
separately purchased target cable assembly. When you install the
M68EM05P18 on the MMDS05, the target cable passes through the slit
in the station module enclosure. Connector J1 is used as a connection
to a logic analyzer. DIN connectors P1 and P2 connect the EM and a
development system platform board.
Location XU5 is the resident MCU. Switch SW1 enables or disables port
A mask options. A wirewrap area is at the lower right corner of the
M68EM05P18 board.

Target Cable Assemblies
To connect your M68EM05P18 to a target system, you need a
separately purchased target cable assembly. Cable assemblies support
both MC68HC805P18 and MC68HC05P18 emulation and are available
for two MCU packages: dual in-line plastic (DIP) and small outline
integrated circuit (SOIC).
The target cable connects to the emulator via connector J2 on the
M68EM05P18 emulation module. Pin assignments and signal
descriptions for connector J2 can be found in Target Cable Connector
Pin Assignments on page 15.
The drawings in Figure 2 represent a target cable assembly. An
assembly for 28-pin DIP packages consists of a flex cable and a target
head adapter. The assembly for 28-pin SOIC packages requires an
additional SOIC adapter. One end of the flex cable plugs onto
M68EM05P18 connector J2 with orientation shown in Figure 2. The
other end of the flex cable plugs into the target head adapter. The target
head adapter then inserts into either a DIP footprint in a target system or
into the SOIC adapter.
The MCU package in your target system determines the target cable
assembly components required:
• For a 28-pin DIP package, use flex cable M68CBL05A and target
head adapter M68TA05P9P28.
• For a 28-pin SOIC package, use the flex cable assembly for the
28-pin DIP in conjunction with SOIC adapter M68DIP28SOIC.

MMDS/MMEVS Configuration and Operation Introduction
M68EM05P18UM/D
20 MMDS/MMEVS Configuration and Operation MOTOROLA
Introduction
The following paragraphs explain how to configure and use your
M68EM05P18 as part of an MMDS or MMEVS system. For other parts
of system installation and configuration, see either the
MMDS05
Operations Manual
(MMDS05OM/D) or MMEVS05/MMEVS08
Operations Manual
(MMEVS0508OM/D). If you use your M68EM05P18
as part of an HC05EVS, refer to HC05EVS Configuration and
Operation on page 31 for corresponding information.
The topics covered in this chapter are:
•Setting M68EM05P18 Jumper Headers and Switches on page
21 explains how to set the M68EM05P18 jumper headers.
•Remaining System Installation on page 25 covers the final
steps to system installation.
•Personality File Usage on page 26 discusses how the
personality file is used on the M68EM05P18 board.
•MC68HC(8)05P18 Emulation on page 26 explains
considerations pertaining to the MCU you emulate.
NOTE: You can configure an M68EM05P18 already installed in the
system platform board. To do so, remove system power and
then follow the guidance of this chapter.
CAUTION: Be sure to switch off power before you reconfigure an
installed EM. Reconfiguring EM jumper headers with the
power on can damage emulation circuits.
