INTRODUCTION
CHAPTER 1
INTRODUCTION
This user's manual explains connection, configuration, and operation information specific to
the M68EM05F4 Emulator Module (F4EM). The F4EM makes possible emulation and
debugging of target systems based on these microcontroller units (MCUs):
MC68HC705F4 MC68HC05F4
The F4EM can be part of two development systems. This chapter describes those systems
and explains the layout of the F4EM.
The factory installs an MC68HC705F4 resident MCU in the F4EM.
1.1 DEVELOPMENT SYSTEMS
Your F4EM 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 F4EM: 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 moulded 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.
•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.

INTRODUCTION
•MMDS05 documentation — an MMDS05 operations manual (MMDS05OM/D) and
the appropriate EM user's manual.
As mentioned, your F4EM gives the MMDS05 the ability to emulate the MC68HC(7)05F4
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 F4EM 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 HC05F4 EVS emulates the MC68HC705F4 and the MC68HC05F4
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 F4EM 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.

INTRODUCTION
1.2 EM LAYOUT
Figure 1-1 shows the layout of the F4EM. Use jumpers J1 and J2 to select the clock source
for the emulator. Jumper header J3 lets you select clock stretching if required. J4 controls the
path of a target reset.
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 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 that is
available separately. If you install the F4EM board in the MMDS05, the target cable passes
through a slit in the MMDS05 enclosure.

MMDS05 CONFIGURATION AND OPERATION
CHAPTER 2
MMDS05 CONFIGURATION AND OPERATION
This chapter explains how to configure and use your F4EM 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 F4EM as part of an HC05EVS system, go to
Chapter 3 for corresponding information.)
Paragraph 2.1 explains how to set F4EM 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 F4EM 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.

MMDS05 CONFIGURATION AND OPERATION
2.1 SETTING F4EM JUMPER HEADERS
Your F4EM has four jumper headers, J1 to J4. This section explains how to configure these
headers.
2.1.1 Clock Source Select Headers (J1, J2)
Jumper headers J1 and J2 determine the source of the clock signal. The diagram below shows
the factory configuration of these jumpers: the fabricated jumper between pins 2 and 3 selects
the F4EM canned oscillator clock source.

Alternatively, you may use a clock source originating from the MMDS05 control board. To
do so, reposition the J1 jumper between pins 1 and 2. Then use the MMDS OSC command
to select clock frequency.
Use Jumper J2 to select between an internal generated clock and an external clock generated
by the target system. If the jumper on J2 is between pins 1 and 2 (selecting external clock),
the position of J1 is not important.

MMDS05 CONFIGURATION AND OPERATION
2.1.2 Clock Stretch Select Header (J3)
Jumper header J3 determines the source of clock stretching (if required). The factory ships
this board with no jumper installed, that is with the clock stretch function disabled. To
enable clock stretch place a jumper between pins 1 and 2 for DACIA cycle stretching (affects
locations $3FE0 - $3FE3) or between pin 2 and 3 for monitor map cycle stretching.

J3
Note: Do not install a pre-fabricated jumper on this header when using the board as part of an
MMDS05 system.
2.1.3 Reset Select Header (J4)
Jumper header J4 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 J4 configuration for a F4EM that is part of an MMDS05.

NOTE: Using the F4EM with the fabricated jumper installed between pins 2 and 3 will
interfere with correct operation of the RESETIN and RESETOUT commands. The J4 pins 2-
and-3 configuration is not correct for a F4EM that is part of an MMDS05 system.

MMDS05 CONFIGURATION AND OPERATION
2.2 THE EMULATED MCU
Your MMDS05 system uses a specific personality file for the MCU type being emulated.
For example, to emulate an MC68HC05F4 or MC68HC705F4 MCU, the system uses
personality file 00220Vxx.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 F4EM. 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
EMULATED
MCU PERSONALITY FILE RESIDENT MCU COMMENTS
MC68HC705F4 00220Vxx.MEM MC68HC705F4 See paragraphs 2.2.1.
MC68HC05F4 00220Vxx.MEM MC68HC705F4 See paragraphs 2.2.2.
MMDS05 software loads the default personality file for the EM board installed on power-
up. 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 start-up. (For more information about the STARTUP.05 script file, see the SCRIPT
command explanation in the MMDS05 operations manual.)
Note:- For correct operation you must install the personality file in the same directory as the
MMDS05 software, place only the latest versions of these files in this directory. If the
personality file required for the EM board is not in the same directory, the MMDS05 will
prompt you for one. You may select one anywhere on the drive on which the MMDS05
software resides.
2.2.1 MC68HC705F4 Emulation Limitations
The open-drain outputs on the port pins PB0 and PB1 will not match the silicon precisely.
The COP reset circuitry will function correctly but only if bit X of location $1F equals 1.
For more information about the MC68HC705F4, see the corresponding technical data books.
2.2.2 MC68HC05F4 Emulation Limitations
Limitations are as per 2.2.1.

MMDS05 CONFIGURATION AND OPERATION
2.3 REMAINING SYSTEM INSTALLATION
When you have configured headers J1 to J4 and made sure that the resident MCU is
appropriate, you are through with F4EM configuration:
•To install the F4EM 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
stand-offs. Connect the target cable, if appropriate. Replace the panel.
•If your F4EM 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).

Paragraph 3.1 explains how to set F4EM jumper headers. Paragraph 3.2 explains
considerations pertaining to the MCU you emulate. Paragraph 3.3 lists limitations on using
the F4EM in an HC05EVS. Paragraph 3.4 explains pin assignments and signal descriptions
for the logic analyzer connector (P1). Paragraph 3.5 explains remaining system configuration.
Note that you can configure a F4EM already installed on the HC05EVS platform board. To
do so, disconnect platform-board power, then follow the guidance of this chapter.
CAUTION
Be sure to disconnect power if you reconfigure an installed EM. Reconfiguring
EM jumper headers with power left on can damage HC05EVS circuits.

HC05EVS CONFIGURATION AND OPERATION
3.1 SETTING F4EM JUMPER HEADERS
Your F4EM has FIVE jumper headers, J1 to J5. Sections 3.1 explain how to configure these
headers.
3.1.1 Clock Source Select Headers (J1, J2)
Jumper headers J1 and J2 determines the source of the clock signal. The diagram below
shows the factory configuration of these jumpers: the fabricated jumper between pins 2 and 3
selects the F4EM canned oscillator clock source.

Jumper J2 can be used to select between an internal generated clock or a external clock
generated by the target system. If the target clock is selected by placing the jumper on J2
between pins 1 and 2 the position of the fabricated jumper on J1 does not matter.
NOTE: The only valid position of the J1 fabricated jumper is between pins 2 and 3 when
using the F4EM as part of an EVS system.
3.1.2 Clock Stretch Select Header(J3)
Jumper header J3 determines the source of clock stretching (if required). By default board is
shipped from the factory with no jumper installed. ie with the clock stretch funxtion disabled.
To enable clock stretch add jumper between pins 1 and 2 for DACIA cycle stretching (affects
locations $3FE0 - $3FE3) or between pin 2 and 3 for monitor map cycle stretching.

HC05EVS CONFIGURATION AND OPERATION
3.3 EVS LIMITATIONS
This paragraph explains the limitations that apply to using your F4EM 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.
