The D32EM can be part of two development systems. This chapter describes those systems and explains the layout of the D32EM. 1.1 DEVELOPMENT SYSTEMS Your D32EM 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.
MC68HC05D-series 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 D32EM as part of an MMDS05 system.
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). MC68HC05C9 Figure 1-1. HC05D32 Emulator Module M68EM05D32/D MOTOROLA...
P1 are in Chapter 3. To configure your D32EM for use as part of an MMDS05, follow the instructions of Chapter 2. To configure your D32EM for use as part of an HC05EVS, follow the instructions of Chapter 3. M68EM05D32/D MOTOROLA...
EM jumper headers with power left on can damage MMDS05 circuits. 2.1 SETTING D32EM JUMPER HEADERS Your D32EM has four jumper headers, J1 through J4 and two switch arrays S1 and S2. Paragraphs 2.1.1. through 2.1.4 explain how to configure these headers and switches. M68EM05D32/D MOTOROLA...
J3 jumper between pins 2 and 3, then use the MMDS05 OSC command to select a frequency. To use a clock source originating from the target system position the J3 jumper between pins 2 and 3, then position the J2 jumper between pins 1 and 2. M68EM05D32/D MOTOROLA...
This is the only correct J4 configuration for a D32EM that is part of an MMDS05. FABRICATED JUMPER TRGT NOTE The J2 pins 2-and-3 configuration is not correct for a D32EM that is part of an MMDS05 system. Such a configuration would interfere with correct operation of the RESETIN and RESETOUT commands. M68EM05D32/D MOTOROLA...
Jumper header J1 and switch array S2 are required for a different configuration of the printed circuit board. For correct D32EM operation Jumper J1 must always be in the C/D position and the switch array must have all switches in the closed position as shown below.

• If your D32EM already is installed in the station module, reconnect the target cable (if necessary). Replace the panel. At this point, you are ready to make remaining cable connections, as necessary, and restore power. For instructions, consult the MMDS05 operations manual (MMDS05OM/D). M68EM05D32/D MOTOROLA...

FABRICATED JUMPER TRGT Alternatively, you may enable the target system to reset the D32EVS. To do so: • Reposition the D32EM J4 jumper between pins 2 and 3, and • Insert a fabricated jumper into platform-board header J3. M68EM05D32/D MOTOROLA...

Limitation 5. COP. The computer operating properly (COP) update register serves as an EPROM location for the resident MCU. Accordingly, the platform-board write-protect jumper header must enable write protection. Otherwise, any writes to the COP update register change the value stored in user pseudo ROM.
