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.

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 F4EM for use as part of an MMDS05, follow the instructions of Chapter

2. To configure your F4EM for use as part of an HC05EVS, follow the instructions of

Chapter 3.

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.

MMDS EM

TOSC1 (J1)

FABRICATED

JUMPERS

1(2) (3)

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.
