CHAPTER 1 INTRODUCTION
This user’s manual explains connection, configuration, and operation
information specific to the M68EM05BS8 Emulator Module (hereafter
referred to as BS8EM). The BS8EM makes possible emulation and
debugging of MC68HC05BS8 microcontroller unit (MCU) based target
systems.
The BS8EM can be part of two development systems. This chapter
describes those systems and explains the layout of the BS8EM.
1.1 DEVELOPMENT SYSTEMS
Your BS8EM 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 BS8EM: 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.

HC05BS8EM USER’S MANUAL
MOTOROLA

1•MMDS05 documentation -- an MMDS05 operations manual
(MMDS05OM/D) and the appropriate EM user’s manual.
As mentioned, your BS8EM gives the MMDS05 the ability to emulate
the MC68HC05BS8 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 BS8EM 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 BS8EM: 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 BS8EM emulates the MC68HC05BS8 MCU. 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 BS8EM 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 BS8EM. Jumper header P4 controls
the path of a target reset. Jump header P6 lets you select the clock-signal
source. Jumper header P9 allows you to use the on-board emulation
RAM instead of the internal EEPROM of the device during product
development.
Connectors P7 and P8, for a 44-pin QFP or a 52-pin PLCC cable assem-
bly, (purchased separately from the BS8EM.) provide an interface to
your target system. If you install the BS8EM 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 TARGET CONNECTORS AND CABLE INFORMATION
Figure 1-2 shows the pin assignments for connectors P7 and P8. For sig-
nal descriptions, consult the technical data book for the M68HC05BS8
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 BS8EM for use as part of an MMDS05, follow the
instructions of Chapter 2. To configure your BS8EM as part of an
HC05EVS, follow the instructions of Chapter 3.

To connect your BS8EM to your target system via a separately pur-
chased, target cable and head assembly, follow the instructions below.
Figure 1-3 is a generic representation of a Motorola supplied target
cable assembly, which consists of a flexible cable and a QFP/PLCC tar-
get head. To emulate a QFP device, the surface-mount adapter that
comes with the target head is required to be soldered directly to the tar-
get PCB. Emulation of a PLCC device is achieved by fitting the PLCC
target head into the MCU socket of the target system. Table 1-1 shows
the target cable and head part numbers required to form a 44-pin QFP
and a 52-pin PLCC target cable assembly for the BS8EM.
To use a QFP target cable, connect the small square cable terminator (the
one with two 50-mil connectors) of M68CBL05C to
M68TC05BS8FB44. They should be connected in such a way that the
arrow marked on the target head is pointing to the target cable. Next,
connect the large rectangular cable terminator to the BS8EM target con-
nectors P7 and P8. The connector at the far end of the cable should be
connected to P7 and the other to P8. Remove the surface-mount adapter
from the target head and solder it to the target system board, then re-con-
nect the target head back onto the surface-mount adapter.
To use a PLCC target cable, connect the large cable terminator of
M68CLB05B to M68TB05BS8FN52. They should be connected in
such a way that the arrow marked on the target head is pointing to the
target cable. Next, connect the small cable terminator to the BS8EM tar-
get connectors P7 and P8. The connector at the far end of the cable
should be connected to P7 and the other to P8. Plug the target head into
the MCU socket of your target system.
If you install the BS8EM in the MMDS05 station module, run the target
cable through the slit in the station module enclosure.
