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.
