The JB8EM lets you emulate and debug target systems based on the MC68HC908JB8 microcontroller unit (MCU): This section describes Motorola’s two development systems that use the JB8EM, and it explains the JB8EM’s layout. 1.3 Development Systems The JB8EM can be part of two Motorola development systems: • MMDS0508 Motorola Modular Development System (MMDS) • MMEVS0508 Motorola Modular Evaluation System (MMEVS) M68EM08JB8 Emulator Module — Rev. 1 MOTOROLA User’s Manual General Description 9 General Description 1.3.1 Motorola Modular Development System (MMDS) The MMDS 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 MMDS consists of: • Station module — The metal MMDS enclosure containing the control board and the internal power supply • Emulator module (EM) — A separately purchased printed circuit board that enables system functionality for a specific set of MCUs • Two logic clip cable assemblies — Twisted-pair cables that connect the station module to the target system, a test fixture, a clock, an oscillator, 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 or pod B. Leads at the other end of each cable terminate in female probe tips. Ball clips come with the cable assemblies. • 9-lead RS-232 serial cable — Cable that connects the station module to the host computer RS-232 port • 9- to 25-pin adapter — A molded assembly that connects the 9-pin cable to a 25-pin serial port • System software — MCUez™ software on CD-ROM and P&E Microcomputer System, Inc. software on CD-ROM • MMDS documentation — MMDS Operations Manual, Motorola document order number MMDS0508OM/D; the MCUez software manual, included with the MCUez software package; a system software manual, included with the P&E Microcomputer System, Inc.’s MMDS0508 software package; and this emulator user's manual User’s Manual 10 M68EM08JB8 Emulator Module — Rev. 1 General Description MOTOROLA General Description Development Systems MMDS baud rates are selected by the user at 2400, 4800, 9600, 19,200, 38,400, or 57,600. As mentioned, the JB8EM gives the MMDS the ability to emulate target systems based on MC68HC908JB8 MCUs. By substituting a different EM, MMDS can be enabled to emulate target systems based on a different MCU. (A local Motorola representative can explain all the EMs available.) 1.3.2 Motorola Modular Evaluation System (MMEVS) An MMEVS is an economical, two-board tool for designing, debugging, and evaluating target systems based on MC68HC05 or MC68HC08 MCUs. A complete MMEVS consists of: • Platform board (PFB) — The bottom board, which supports the emulator module; has connectors for power and for a terminal or host computer • Emulator module (EM) — A separately purchased printed circuit board that enables system functionality for a specific set of MCUs; fits onto the PFB • RS-232 serial cable — A separately purchased cable that connects the PFB to the host computer RS-232 port • System software — MCUez™ software on CD-ROM and P&E Microcomputer System, Inc. software on CD-ROM • MMEVS documentation — MMEVS Operations Manual, Motorola document order number MMEVSOM/D; the MCUez software manual, included with the MCUez software package; a system software manual, included with the P&E Microcomputer System, Inc.’s MMDS0508 software package; and this emulator user's manual An MMEVS features automatic selection of the communication baud rate from these choices: 2400, 4800, 9600, 19,200, 38,400, or 57,600. With a JB8EM, the MMEVS emulates target systems based on MC68HC908JB8 MCUs. By substituting a different EM, the MMEVS can be enabled to emulate target systems based on a different MCU. (A local Motorola representative can explain all the EMs available.) M68EM08JB8 Emulator Module — Rev. 1 MOTOROLA User’s Manual General Description 11 General Description Section 2. Configuration and Operation explains how to configure and use the JB8EM as part of an MMDS or MMEVS system. 1.4 EM Layout Figure 1-1 shows the layout of the JB8EM. Figure 1-1.

For other parts of system installation or configuration, see the MMDS or MMEVS hardware manuals. NOTE: A JB8EM already installed in an MMDS station module can be reconfigured. To do so, switch off station-module power, then follow the guidance in this section. Similarly, JB8EM that is already installed on the MMEVS platform board can be reconfigured, provided that platform-board power is disconnected. CAUTION: Be sure to switch off or disconnect power when reconfiguring an installed EM. Reconfiguring EM jumper headers with the power on can damage system circuits. M68EM08JB8 Emulator Module — Rev. 1 MOTOROLA User’s Manual Configuration and Operation 15 Configuration and Operation ESD CAUTION: Ordinary amounts of static electricity from clothing or the work environment can damage or degrade electronic devices and equipment. For example, the electronic components installed on printed circuit boards are extremely sensitive to electrostatic discharge (ESD). Wear a ground wrist strap whenever handling any printed circuit board. This strap provides a conductive path for safely discharging static electricity to ground. 2.3 Setting Jumper Headers The JB8EM has two jumper headers. Table 2-1 contains a summary of settings for these headers. 2.3.1 Pulldown Enable Jumper (P3) and 2.3.2 Clock Source Header (P5) give additional information about each jumper header. Table 2-1. Jumper Headers Jumper Header Type P3 Description Jumper between pins 1 and 2; connects a 1MΩ resistor between the D– pin of the MC68HC908JB8 and ground. This prevents a USB reset when the D– signal from the target system is in a high impedeance state. 1 2 Jumper between pins 1 and 2; selects the clock signal from the MMDS control board or MMEVS platform board P5 1 3 5 2 4 6 Jumper between pins 3 and 4 (factory default); selects the onboard 6MHz crystal oscillator Jumper between pins 5 and 6; selects an external clock source for the OSC1 input signal from target head connectors User’s Manual 16 M68EM08JB8 Emulator Module — Rev. 1 Configuration and Operation MOTOROLA Configuration and Operation Setting Jumper Headers 2.3.1 Pulldown Enable Jumper (P3) Install a jumper on jumper header P3 to connect a 1MΩ resistor between D– of MC68HC908JB8 and ground. DO NOT remove this jumper; if removed, proper operation of the system cannot be guaranteed. Figure 2-1 shows the default factory jumper header configuration, which has a fabricated jumper installed on jumper header P3 between pins 1 and 2. P3 Default 1 • • 2 Figure 2-1. Jumper Header P3 2.3.2 Clock Source Header (P5) Jumper header P5 in Figure 2-2 determines the clock signal source. The factory configuration (the fabricated jumper between pins 3 and 4) selects the on-board 6MHz crystal oscillator at location Y1. P5 MMDS 1 • • 2 6 MHz 3 • • 4 OSC1 5 • • 6 Figure 2-2. Jumper Header P5 Alternately, two other clock signal sources can be selected, as shown in Figure 2-2. NOTE: • To select the clock signal from the MMDS control board or MMEVS platform board install the fabricated jumper between pins 1 and 2. Then use the system software to select a frequency. • To select the target system as the clock source, install the fabricated jumper between pins 5 and 6. Ensure that the clock source (OSC1) is connected to the EM through the target cable, connector P7 pin 3. Only one jumper should be inserted on jumper header P5 at a time. Inserting multiple jumpers in P5 might damage the JB8EM. M68EM08JB8 Emulator Module — Rev. 1 MOTOROLA User’s Manual Configuration and Operation 17 Configuration and Operation 2.4 Remaining System Installation When both jumper headers are configured, follow these steps to complete the JB8EM installation: • To install the JB8EM in an MMDS station module, remove the entire top half of the station-module enclosure. Fit together EM connectors P1 and P9 (on the bottom of the board) and control-board connectors P1 and P2. Snap the corners of the EM onto the plastic standoffs. • To install the JB8EM on an MMEVS platform board, fit together EM connectors P1 and P9 (on the bottom of the board) and platform-board connectors P3 and P4. Snap the corners of the EM onto the plastic standoffs. • Copy the personality file from the provided P&E or MCUez CD-ROMs to the directory that contains the debugging software. The personality file for the MC68HC908JB8 MCU are: – 00C57Vxx.MEM - MCUez personality file – 00457Vxx.MEM - P&E personality file At this point, make any system cable connections and restore power. For instructions, consult the MMDS or MMEVS operations manuals. User’s Manual 18 M68EM08JB8 Emulator Module — Rev. 1 Configuration and Operation MOTOROLA User’s Manual — M68EM08JB8 Section 3.

Figure 3-3 shows how one end of the flex cable plugs into the JB8EM module, and it also shows how the target head connects into the target system. If the JB8EM is installed in the MMDS station module, run the flex cable through the slit in the station-module enclosure.
