CHAPTER 1 INTRODUCTION

This user’s manual explains connection, conﬁguration, and operation

information speciﬁc to the M68EM05A24 Emulator Module (hereafter

referred to as A24EM). The A24EM makes possible emulation and

debugging of MC68HC705A24/MC68HC05A16 microcontroller unit

(MCU) based target systems.

The A24EM can be part of two development systems. This chapter

describes those systems and explains the layout of the A24EM.

1.1 DEVELOPMENT SYSTEMS

Your A24EM 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 A24EM: 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.

HC05A24EM 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 A24EM gives the MMDS05 the ability to emulate

the MC68HC705A24 and MC68HC05A16 MCUs. 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 A24EM 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 A24EM: 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 A24EM emulates the MC68HC705A24 and

MC68HC05A16 MCUs. By substituting a different EM, you can enable

your HC05EVS to emulate an MCU of a different series. (Your Motor-

ola representative can explain all the EMs available.)

Chapter 3 explains how to conﬁgure and use your A24EM 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 A24EM. Jumper header P4 controls

the path of a target reset. Jumper header P5 can be used to disable the

internal COP of the MCU during software development. Jump header

P6 lets you select the clock-signal source. Jump header P9 selects the

internal oscillator clock divider.

Connectors P7 and P8, for a 56-pin SDIP cable assembly, (purchased

separately from the A24EM.) provide an interface to your target system.

If you install the A24EM 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 and 1-3 show the pin assignments for connectors P7 and P8.

For signal descriptions, consult the technical data book for the

M68HC05A24 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 A24EM for use as part of an MMDS05, follow the

instructions of Chapter 2. To conﬁgure your A24EM as part of an

HC05EVS, follow the instructions of Chapter 3.

1To connect your A24EM to your target system via a separately pur-

chased, target cable and head assembly, follow the instructions below.

Figure 1-4 is a generic representation of a Motorola supplied target

cable assembly, which consists of a ﬂexible cable and a SDIP target

head. Emulation of a SDIP device is achieved by ﬁtting the SDIP target

head into the MCU socket of the target system. Table 1-1 shows the tar-

get cable and head part numbers required to form a 56-pin SDIP target

cable assembly for the A24EM.

To use a SDIP target cable, connect the large cable terminator of

M68CLB05B to M68TB05A24B56. 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 A24EM target

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 A24EM in the MMDS05 station module, run the target

cable through the slit in the station module enclosure.
