INTRODUCTION
M68HC05E24EM/D2 1-1 MOTOROLA
CHAPTER 1
INTRODUCTION
This user's manual explains connection, configuration, and operation information specific to
the HC05E24EM Emulator Module (E24EM). The E24EM makes possible emulation and
debugging of target systems based on these microcontroller units (MCUs):
MC68HC705E24 MC68HC05E16
The E24EM can be part of two development systems. This chapter describes those systems
and explains the layout of the E24EM.
The factory installs an MC68HC705E24 resident MCU in the E24EM.
1.1 DEVELOPMENT SYSTEMS
Your E24EM 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 environment 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
module enclosure to connect directly to the emulator module.)
•an emulator module (EM) — such as the E24EM: a printed circuit board that
enables system functionality for a specific set of MCUs. The EM fits into the station
module through a sliding panel in the enclosure top. The EM has a connector for the
target cable.
•two logic clip cable assemblies — twisted-pair cables that connect the station
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 or pod B. Leads at the other end of each cable terminate
in female probe tips. Ball clips come with the cable assemblies.

INTRODUCTION
M68HC05E24EM/D2 1-2 MOTOROLA
•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 molded assembly that lets you connect the 9-lead cable to
a 25-pin serial port.
•system software — software, on 3-1/2 inch diskettes.
•MMDS05 documentation — an MMDS05 operations manual (MMDS05OM/D) and
the appropriate EM user's manual.
As mentioned, your E24EM gives the MMDS05 the ability to emulate the
MC68HC(7)05E24/16 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 E24EM as part of an MMDS05 system. For
information about MMDS05 software or the station module, see the MMDS05 operations
manual. For layout and configuration 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, debugging, 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 F4EM: a printed circuit board that enables
system functionality for a specific set of MCUs. The EM fits onto the PFB. The EM
has connectors for a target cable and for 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 (HC05EVSOM/D)
and the appropriate EM user's manual.
As mentioned, your HC05E24 EVS emulates the MC68HC705E24 and the MC68HC05E16
MCUs. By substituting a different EM, you can enable your HC05EVS to emulate an MCU of
a different series. (Your Motorola representative can explain all the EMs available.)
Chapter 3 explains how to configure and use your E24EM 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
corresponding EM user's manual.

1.2 EM LAYOUT
Figure 1-1 shows the layout of the E24EM. Jumper header J1 selects factory test or user
mode. J2 controls the path of a target reset. J3 and J4 allow the clock source to be selected. J5
selects between MMDS05 and EVS operation.
Connector P1 is for 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). Finally, Connectors P4 and P5 allow for connection of a target cable
which is available separately. If you install the E24EM board in the MMDS05, the target cable
passes through a slit in the MMDS05 enclosure.

CHAPTER 2
MMDS05 CONFIGURATION AND OPERATION
This chapter explains how to configure and use your E24EM as part of an MMDS05. For
other parts of system installation or configuration, see the MMDS05 operations manual
(MMDS05OM/D). (If you intend to use your E24EM as part of an HC05EVS system, go to
Chapter 3 for corresponding information.)
Paragraph 2.1 explains how to set E24EM jumper headers. Paragraph 2.2 explains
considerations pertaining to the MCU you emulate. Paragraph 2.3 explains remaining system
installation.
Note that you can configure a E24EM already fitted in the MMDS05 station module enclosure.
To do so, switch off station-module power, remove the top panel, 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.

2.2 THE EMULATED MCU
Your MMDS05 system uses a specific personality file for the MCU type being emulated. For
example, to emulate an MC68HC705E24 MCU, the system uses personality file
0020DVxx.MEM this file contains device specific information such as memory map, required
by the MMDS05 for correct operation.
Table 2-1 lists all the personality files that pertain to the E24EM. Note that personality file
names follow the pattern 00ZZZVxx.MEM, where ZZZ is the EM identifier or MCU
name, and xx is the version of the file.
Table 2-1. MCUs and Personality Files

MCU PERSONALITY FILE RESIDENT MCU COMMENTS
MC68HC705E24 0020DVxx.MEM MC68HC705E24 See paragraphs 2.2.1.
MC68HC05E16 00ME16Vxx.MEM MC68HC705E24 See paragraphs 2.2.2.
MMDS05 software loads the default personality file for the EM board installed on powerup.
To manually load a different personality file, use the LOADMEM command. (For more
information about the LOADMEM command, see the explanation in the MMDS05 operations
manual.)
Alternatively, you can insert the line LOADMEM 00ZZZVxx.MEM in the STARTUP.05 script
file. This way, the system automatically loads the specified personality file as part of system
startup. (For more information about the STARTUP.05 script file, see the SCRIPT command
explanation in the MMDS05 operations manual.)
Note:- For correct operation the personality file must be installed in the same directory as the
MMDS05 software, only the latest versions of these files should be held in this directory. If the
personality file required for the EM board is not installed in the same directory you will be
prompted for one. This may be selected anywhere on the drive on which the MMDS05
software resides.

2.3 REMAINING SYSTEM INSTALLATION
When you have configured headers J1 to J5 and made sure that the resident MCU is
appropriate, you are through with E24EM configuration:
•To install the E24EM 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 corners of the EM onto the plastic
standoffs. Connect the target cable, if appropriate. Replace the panel.
•If your E24EM 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).

M68HC05E24/D2 3-5 MOTOROLA
3.3 EVS LIMITATIONS
This paragraph explains the limitations that apply to using your E24EM in an HC05EVS.
(These limitations apply regardless of the resident MCU.)
Limitation 1. CLI/RTI. You may not trace a clear interrupt mask (CLI) or return from
interrupt (RTI) instruction with an interrupt enabled and pending, due to MCU interrupt
handling. Attempting such a trace causes an interrupt in the monitor map; this forces a
software reset of the HC05EVS. User breakpoints remain in the user map as SWI instructions;
you must remove such SWI instructions.
Limitation 2. Branch. Do not trace a conditional branch instruction (such as BRCLR) that
branches to itself. As the monitor places an SWI instruction on the object of the branch, the
system never would execute the instruction. However, it would appear to you that the
instruction had executed. You may enter a G command while the PC points to this type of
instruction as long as the instruction is not a breakpoint address.
Limitation 3. IRQ/SWI. Whenever possible, avoid mixing interrupt requests (IRQs) and
user software interrupts (SWIs). This prevents a possible IRQ-SWI timing problem: a
concurrent hardware interrupt and SWI could cause an HC05EVS failure that could stop
program execution. To recover from such a failure (which occurs very infrequently,
statistically), press the master reset switch (SW3).
Limitation 4. Memory Map. You must be aware of the memory map of the MCU being
simulated; be sure to use only valid ROM locations. The HC05EVS does not provide
protection to limit user programs to the exact amount of MCU ROM available. (For
information about memory maps, consult the technical data book for the MCU.)
Limitation 5. COP. The computer operating properly (COP) update register serves as an
EPROM location for the resident MCU. Accordingly, the platform-board write-protect jumper
header must enable write protection. Otherwise, any writes to the COP update register change
the value stored in user pseudo ROM.
