CHAPTER 1 INTRODUCTION
This user’s manual explains connection, configuration, and operation
information specific to the HC05L1EM Emulator Module (hereafter
referred to as L1EM). The L1EM makes possible emulation and debug-
ging of MC68HC05L1 microcontroller unit (MCU) based target sys-
tems.
The L1EM can be part of two development systems. This chapter
describes those systems and explains the layout of the L1EM.
1.1 DEVELOPMENT SYSTEMS
Your L1EM can be part of two Motorola development tools: the HC05
Motorola Modular Development System (MMDS05) or the
M68HC05EVS Evaluation System (HC05EVS).
1.1.1 Motorola Modular Development System (MMDS05)
The MMDS05 is an emulator system that provides a bus state analyzer
and real-time memory windows. The unit’s integrated design environ-
ment includes an editor, an assembler, user interface, and source-level
debug. A complete MMDS05 consists of:
•a station module -- the metal MMDS05 enclosure, containing the
control board and the internal power supply. Most system cables
connect to the MMDS05 station module. (The cable to an optional
target system, however, runs through an aperture in the station mod-
ule enclosure to connect directly to the emulator module.)
•an emulator module (EM) -- such as the L1EM: a printed circuit
board that enables system functionality for a specific MCU. The EM
fits into the station module through a sliding panel in the enclosure
top. The EM has connectors for the target cable.
•two logic clip assemblies -- twisted-pair cables that connect the sta-
tion module to your target system, a test fixture, a clock, 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 and pod B. Leads at the other end of each cable terminate in
female probe tips. Ball clips come with the cable assemblies.
•a 9-lead RS-232 serial cable -- the cable that connects the station
module to the host computer RS-232 port.
•a 9 to 25-pin adapter -- a moulded assembly that lets you connect
the 9-lead cable to a 25-pin serial port.
•system software -- software, on 3-1/2 inch diskettes.

HC05L1EM USER’S MANUAL
MOTOROLA
1-2
1•MMDS05 documentation -- an MMDS05 operations manual
(MMDS05OM/D) and the appropriate EM user’s manual.
As mentioned, your L1EM gives the MMDS05 the ability to emulate the
MC68HC05L1 MCU. By substituting a different EM, you can enable
your MMDS05 to emulate an MCU of a different series. (Your Motorola
representative can explain all the EMs available.)
Chapter 2 explains how to configure and use your L1EM as part of an
MMDS05 system. For information about MMDS05 software or the sta-
tion module, see the MMDS05 operations manual. For layout and con-
figuration information pertaining to a different EM, see the
corresponding EM user’s manual.
1.1.2 M68HC05EVS Evaluation System (HC05EVS)
An HC05EVS is an economical, two-board tool for designing, debug-
ging, and evaluating target systems based on an MC68HC05 MCU. A
complete HC05EVS consists of:
•a platform board (PFB) -- the bottom board, which supports the
emulator module. The platform board has connectors for power and
for the terminal or host computer.
•an emulator module (EM) -- such as the L1EM: a printed circuit
board that enables system functionality for a specific MCU. The EM
fits onto the PFB. The EM has connectors for a target cable and a
cable to a logic analyzer.
•an RS-232 serial cable -- the cable that connects the PFB to the host
computer RS-232 port.
•system software -- software, on 3-1/2 inch diskettes.
•HC05EVS documentation -- an HC05EVS operations manual and
the appropriate EM user’s manual.
As mentioned, your HC05L1 EM emulates the MC68HC05L1 MCU.
By substituting a different EM, you can enable your HC05EVS to emu-
late an MCU of a different series. (Your Motorola representative can
explain all the EMs available.)
Chapter 3 explains how to configure and use your L1EM as part of an
HC05EVS system. For information about HC05EVS software or the
platform board, see the HC05EVS operations manual. For layout and
configuration information pertaining to a different EM, see the corre-
sponding EM user’s manual.

1.2 EM LAYOUT
Figure 1-1 shows the layout of the L1EM. Jumper header P4 controls the
path of a target reset. Jumper header P5 allows you select the frequency
of the L1EM on-board clock source. Jumper header P6 lets you select
the clock-signal source.
Connectors P7 and P8, for a 64-pin QFP or 56-pin S-DIP cable assem-
bly, (purchased separately from the L1EM.) is the interface to a target
system. If you install the L1EM in the MMDS05 station module, the tar-
get cable passes through the slit in the station module enclosure. Con-
nector P1 connects to a logic analyzer. (Connector P1 has more
significance for an EVS system, as an MMDS05 system includes a bus
analyzer.) Expansion header connectors P2 and P3 connect together the
EM and the control board (for an MMDS05) or the EM and the platform
board (for an EVS).
1.3 CONNECTOR PIN ASSIGNMENTS (P4 AND P5)
Figure 1-2 and 1-3 show the pin assignments for connectors P7 and P8.
For signal descriptions, consult the technical data book for the specific
MCU.
As connector P1 has more importance to an HC05EVS than to an
MMDS05, pin assignments for connector P1 are in Chapter 3.
To configure your L1EM for use as part of an MMDS05, follow the
instructions of Chapter 2. To configure your L1EM as part of an
HC05EVS, follow the instructions of Chapter 3.

CHAPTER 2 MMDS05 CONFIGURATION AND OPERATION
This chapter explains how to configure and use your L1EM as part of an
MMDS05. For other parts of system installation or configuration, see
the MMDS05 operations manual (MMDS05OM/D). (If you will use
your L1EM as part of an HC05EVS system, go to Chapter 3 for corre-
sponding information.)
Paragraph 2.1 explains how to set L1EM jumper headers. Paragraph 2.2
explains how to install personality and help files pertaining to the
L1EM. Paragraph 2.3 lists limitations on using the L1EM in an
MMDS05. Paragraph 2.4 explains remaining system installation.
Note that you can configure an L1EM already installed in the MMDS05
station module enclosure. To do so, switch off station-module power,
remove the hatch, then follow the guidance of this chapter.
CAUTION
Be sure to switch off power if you reconfigure an
installed EM. Reconfiguring EM jumper headers with
power left on can damage MMDS05 circuits.
2.1 SETTING L1EM JUMPER HEADERS
Your L1EM has three jumper headers, P4, P5 and P6. Paragraphs
2.1.1.through 2.1.3 explain how to configure these headers.
2.1.1 Reset Select Header (P4)
Jumper header P4 controls the path of a target reset. The diagram below
shows the factory configuration: the fabricated jumper between pins 1
and 2 enables your software to control resets. This is the only correct P4
configuration for an L1EM that is part of an MMDS05.

The P4 pins 1 and 2 configuration is not correct for an
L1EM that is part of an MMDS05 system. Such a config-
uration would interfere with correct operation of the
RESETIN and RESETOUT commands.
2.1.2 Frequency Select Header (P5)
Jumper header P5 determines the frequency of the L1EM clock source.
There are eight possible choices of frequencies and the user can select
one of them by installing a jumper across the appropriate jumper header
pins. The diagram below shows the factory configuration: the factory
configuration has a fabricated jumper installed between pins 1and 2. (i.e.
selects the 4.00 MHz clock source.)

22.2 INSTALLING PERSONALITY AND HELP FILES
L1EM software, on a 3.5” diskette, consists of these files (where xx
denotes a version number):
• 00302Vxx.MEM Personality file (Each personality file cus-
tomizes the MMDS05 host software for one
or more specific MCUs.)
• 00302Vxx.HLP HELP windows specific to the personality
file.
Note that files 00302Vxx.MEM and 00302Vxx.HLP are specific to the
L1EM. You will receive corresponding personality and help files for
each additional EM you order.
2.2.1 Personality File
Installation of the personality file (00302Vxx.MEM) consists of copy-
ing the file from the distribution diskette to a hard disk. Personality files
are usually installed in the directory from which the MMDS05 software
is executed. If a personality file is not located in that directory, the
MMDS05 software displays a window with which the user can search
the directory structure to find the correct file.
More than one personality file can be installed; the MMDS05 operating
software automatically loads the personality file that corresponds to the
currently-connected EM board upon powerup.
2.2.2 Help File
Installation of the help file (00302Vxx.HLP) consists of copying the file
from the distribution diskette to a hard disk. This file must be installed
in the directory from which the MMDS05 software is executed. If it is
not located in that directory, no help information pertaining to the
MC68HC05L1 MCU will be displayed when the CHIPSINFO com-
mand is used.

2.3 MMDS05 LIMITATIONS
This paragraph explains the limitations that apply to using your L1EM
in an MMDS05 system.
•Limitation 1. Test Register $0020:
Location $0020 is a test register location when the MC68HC05L1 is
running in emulation mode. The user should avoid writing to this loca-
tion as changing the contents of this register may cause an MCU failure.
2.4 REMAINING SYSTEM INSTALLATION.
When you have configured headers P4, P5 and P6, you are through with
L1EM configuration:
• To install the L1EM in an MMDS05 station module, remove the
panel from the station-module top. Fit together EM connectors P2
and P3 (on the bottom of the board) and control-board connectors
P11 and P12. Snap the mounting holes of the EM onto the plastic
standoffs. Connect the target cable, if appropriate. Replace the
panel.
• If your L1EM already is installed in the station module, reconnect
the target cable, (if necessary). Replace the panel.
At this point, you are ready to make remaining cable connections, as
necessary, and restore power. For instructions, consult the MMDS05
operations manual (MMDS05OM/D).
