Motorola Modular Development System (MMDS05)
HC05A24EM USER'S MANUAL
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.
Your A24EM can be part of two Motorola development tools: the HC05
Motorola Modular Development System (MMDS05) or the
M68HC05EVS Evaluation System (HC05EVS).
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.
