PCB traces, nor cut too deep into the multi-layer circuit board. If the cut-trace short on a jumper header is already cut, you can return the MPB to its default setting by installing a user-supplied fabricated jumper. Figure 2-1. M68MPB334 Parts Location Diagram (top view) M68MPB334UM/D...
HARDWARE PREPARATION AND INSTALLATION Table 2-1. Jumper Header Types Jumper Header Type Symbol Description two-pin with cut-trace Two-pin jumper header with cut-trace short, designated WX, short where X = the jumper header number. If you cut the short, use a fabricated jumper to return the jumper header to its factory default state.

The drawing below shows the factory configuration: a fabricated jumper on pins 1 and 2. This configuration selects the MPB on-board clock source;...
HARDWARE PREPARATION AND INSTALLATION 2.2.2 VDDA Select Header (W2) Jumper header W2 selects the MPB VDDA power source: either MPB power (VDDI) or an external source. The drawing below shows the factory configuration: a cut-trace short between pins 1 and 2. This configuration connects filtered VDDI to VDDA.
HARDWARE PREPARATION AND INSTALLATION 2.2.3 Voltage Reference High Select Header (W3) Jumper header W3 selects the voltage reference high (VRH) source: either MPB power (VDDA) or an external VRH source. The drawing below shows the factory configuration: a fabricated jumper on pins 1 and 2. This configuration selects VDDA as the VRH source.
HARDWARE PREPARATION AND INSTALLATION 2.2.4 Voltage Reference Low Select Header (W4) Jumper header W4 selects the voltage reference low (VRL) source: either MPB power (VSSA) or an external VRL source. The drawing below shows the factory configuration: a fabricated jumper on pins 1 and 2. This configuration selects VSSA as the VRL source.
HARDWARE PREPARATION AND INSTALLATION 2.3 MEVB CONFIGURATION The MEVB contains: • MPB – MCU-device-specific board that defines which MCU is evaluated. • M68MPFB1632 Modular Platform Board (MPFB) – which provides the interface connections to the host computer, logic analyzer connections, and the platform for installing the MPB.

HARDWARE PREPARATION AND INSTALLATION Figure 2-2. MPB – MPFB Interconnection (with SDI Interface) After you have installed the MPB, install the plastic overlay on the MPFB: place the overlay over logic analyzer connectors J12 through J20 and press down. Holes in the overlay slide down over plastic clips on the MPFB.
• Target Control Board (TCB) – the interface between the MPB, target system, and the station module. The TCB is supplied with the MMDS. For more information about the TCB refer to the M68MMDS1632 Motorola Modular Development System User's Manual, MMDS1632UM/D.

3.1 INTRODUCTION This quick start guide is intended for the user who may not be familiar with Motorola’s development tools. This chapter explains the MEVB hardware and software set up for M68MEVB334 operation. Hardware set up consists of configuring the MPB and MPFB jumper headers; software set up consists of installing and running the appropriate macro script file within the debugger.
MEVB QUICK START GUIDE 3.2.2 MPFB Jumper Headers Configure your MPFB jumper headers per the instructions in Table 3-1. Table 3-1 contains information exclusively intended for quick start and ignores the other jumper headers. Table 3-1. MPFB Quick Start Jumper Header Configuration Jumper Header Type...
MEVB QUICK START GUIDE Table 3-1. MPFB Quick Start Jumper Header Configuration (continued) Jumper Header Type Description 1 2 3 Install a jumper on pins 1 and 2 for unrestricted writes to the memory devices in the pseudo ROM sockets (U2 & U4). Install a jumper on pins 1 and 2 to ground the A19 signal to the MPFB memory 1 2 3 arrays.

MEVB QUICK START GUIDE Figure 3-1. MPFB Power Supply Connector CAUTIONS Do not use wire larger than 20 AWG in connector J5. Such wire could damage the connector. Turn off MEVB power when installing or removing the MPB from the MPFB. Sudden power surges could damage MEVB integrated circuits.
MEVB QUICK START GUIDE 3.3.2 Personal Computer – BDM Connection Personal computer communication with the MEVB requires background debug mode (BDM) hardware. Connect your BDM hardware between your computer’s I/O port and the BDM header on the MPFB (MPFB connector J6). The drawing below shows signal assignments for connector J6.
MEVB QUICK START GUIDE 3.4 SOFTWARE INSTALLATION AND MCU INITIALIZATION After you have set up the MEVB hardware you must install the software on your computer. Follow the installation procedure in the appropriate software operations manual. The MCU must be initialized before the MEVB will function. The following is one possible initialization for the MPB334.
