CHAPTER 1 INTRODUCTION
This user’s manual explains connection, configuration, and operation
information specific to the HC05F6EM Emulator Module (hereafter
referred to as F6EM). The F6EM makes possible emulation and debug-
ging of MC68HC05F6 microcontroller unit (MCU) based target sys-
tems.
The F6EM can be part of two development systems. This chapter
describes those systems and explains the layout of the F6EM.
1.1 DEVELOPMENT SYSTEMS
Your F6EM 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 F6EM: 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.

HC05F6EM USER’S MANUAL
MOTOROLA

1•MMDS05 documentation -- an MMDS05 operations manual
(MMDS05OM/D) and the appropriate EM user’s manual.
As mentioned, your F6EM gives the MMDS05 the ability to emulate the
MC68HC05F6 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 F6EM 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 F6EM: 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 HC05F6 EM emulates the MC68HC05F6 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 F6EM 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 F6EM. Jumper header P4 controls the
path of a target reset. Jump header P6 lets you select the clock-signal
source. Jumper headers P9 and P10 enable you to define the state of bit
7 (SCS1) and bit 6 (SCS0) in the system option register ($002C) of the
MCU on power up or reset respectively.
Connectors P7 and P8, for a 44-pin QFP, a 64-pin QFP, or a 42-pin S-
DIP cable assembly, (purchased separately from the F6EM.) is the inter-
face to a target system. If you install the F6EM in the MMDS05 station
module, the target cable passes through the slit in the station module
enclosure. Connector 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).

11.3 CONNECTOR PIN ASSIGNMENTS (P7AND P8)
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 F6EM for use as part of an MMDS05, follow the
instructions of Chapter 2. To configure your F6EM 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 F6EM 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 F6EM as part of an HC05EVS system, go to Chapter 3 for corre-
sponding information.)
Paragraph 2.1 explains how to set F6EM jumper headers. Paragraph 2.2
explains how to install personality and help files pertaining to the F6EM.
Paragraph 2.3 explains remaining system installation.
Note that you can configure an F6EM 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 F6EM JUMPER HEADERS
Your F6EM has four jumper headers P4, P6, P9 and P10. Paragraphs
2.1.1.through 2.1.4 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 F6EM that is part of an MMDS05.

The P4 pins 2 and 3 configuration is not correct for an
F6EM 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 Clock Source Select Header (P6)
Jumper header P6 determines the source of the clock signal. The dia-
gram below shows the factory configuration: the fabricated jumper
between pins 2 and 3 selects the F6EM canned oscillator clock source.
Alternatively, you may use a clock source originating from the control
board. To do so, reposition the P6 jumper between pins 1 and 2, then use
the MMDS05 OSC command to select a frequency.

(bit 7 in the system option register $002C.) The diagram below shows
the factory configuration: the fabricated jumper between pins 1 and 2
sets the default reset value of SCS1 to ‘0’.
Alternatively, the default reset value of SCS1 is set to ‘1’ by removing
the fabricated jumper between pins 1 and 2.
2.1.4 SCS0 Header (P10)
Jumper header P10 lets the user to define the default reset value of
SCS0. (bit 6 in the system option register $002C.) The diagram below
shows the factory configuration: the fabricated jumper between pins 1
and 2 sets the default reset value of SCS0 to ‘0’.
Alternatively, the default reset value of SCS0 is set to ‘1’ by removing
the fabricated jumper between pins 1 and 2.

22.2 INSTALLING PERSONALITY AND HELP FILES
F6EM software, on a 3.5” diskette, consists of these files (where xx
denotes a version number):
• 00307Vxx.MEM Personality file (Each personality file cus-
tomizes the MMDS05 host software for one
or more specific MCUs.)
• 00307Vxx.HLP HELP windows specific to the personality
file.
Note that files 00307Vxx.MEM and 00307Vxx.HLP are specific to the
F6EM. You will receive corresponding personality and help files for
each additional EM you order.
2.2.1 Personality File
Installation of the personality file (00307Vxx.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 (00307Vxx.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
MC68HC05F6 MCU will be displayed when the CHIPSINFO com-
mand is used.

2.3 REMAINING SYSTEM INSTALLATION.
When you have configured headers P4, P6, P9 and P10, you are through
with F6EM configuration:
• To install the F6EM 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 F6EM 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).

CHAPTER 3 HC05EVS CONFIGURATION AND OPERATION
This chapter explains how to configure and use your F6EM as part of an
HC05EVS. For other parts of system installation or configuration, see
the HC05EVS operations manual. (If you will use your F6EM as part of
an MMDS05 system, go to Chapter 2 for corresponding information.)
Paragraph 3.1 explains how to set F6EM jumper headers. Paragraph 3.2
lists limitations on using the F6EM in an HC05EVS. Paragraph 3.3
explains pin assignments and signal descriptions for the logic analyzer
connector (P1). Paragraph 3.4 explains remaining system configuration.
Note that you can configure an F6EM 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.
3.1 SETTING F6EM JUMPER HEADERS
Your F6EM has four jumper headers, P4, P6, P9 and P10. Paragraphs
3.1.1. through 3.1.4 explain how to configure these headers.

33.2 EVS LIMITATIONS
This paragraph explains the limitations that apply to using your F6EM
in an HC05EVS.
•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 break-
points 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. Bus Frequency During Downloading:
To ensure proper operation during downloading, the MCU bus speed
must be set to 1.79 MHz.
