CHAPTER 1
GENERAL INFORMATION
1.1 INTRODUCTION
This manual provides general information, hardware preparation, installation
instructions, a quick start guide, support information, and schematics for the
M68MPB916R3 MCU Personality Board (MPB). The MPB is one component of
Motorola’s modular approach to microcontroller unit-based product development.
This modular approach lets you easily configure our development systems to fit
your requirements. The MPB916R3 lets you emulate/evaluate these MCUs:
• MC68HC16R1
• MC68HC916R1
• MC68HC16R3
• MC68HC916R3
The MPB may be used in either the M68MMDS1632 Motorola Modular
Development System (MMDS) or the M68MEVB1632 Modular Evaluation
Board (MEVB). Alternately, you may install the MPB directly in your target
system if the target system includes a modular active probe interconnect (MAPI)
interface. The MCU device on the MPB defines which MCU is emulated/
evaluated by the MMDS or MEVB. Both systems are invaluable tools for
designing, debugging, and evaluating MCU operation of the M68HC16 and
M68300 MCU Families. By providing the essential MCU timing and I/O
circuitry, these systems simplify user evaluation of prototype hardware/software
products.
The MPB includes:
• M68MPB916R3 MCU Personality Board (MPB)
• Plastic overlay for use with the MEVB – pin outs for the logic analyzer
connectors on the MPFB
• Documentation (this manual)

CHAPTER 2
HARDWARE PREPARATION AND INSTALLATION
2.1 INTRODUCTION
This chapter provides unpacking instructions, hardware preparation information,
and installation instructions for the MPB.
When you unpack the MPB from its shipping carton, verify that all items are in
good condition. Save packing material for storing and shipping the MPB.
NOTE
Should the MPB arrive damaged, save all packing material, and
contact the carrier’s agent.
2.2 HARDWARE PREPARATION
This portion of the manual explains how to prepare the MPB before use, as well
as how to configure the MPB for system operation.This section also explains
MPB installation in the MMDS and MEVB.
The MPB has been factory tested and is shipped with installed jumpers. A jumper
installed on a jumper header provides a connection between two points in the
MPB circuit. The MPB has two types of jumper headers: three-pin and two-pin
with a cut-trace short. A cut-trace short has a copper trace between the feed-
through holes (bottom or solder side of the MPB). Table 2-1 describes each type
of jumper header.
The MPB has five jumper headers (for which Table 2-2 is a quick reference
guide). You may reconfigure these jumper headers to customize MPB
functionality. The following paragraphsexplain each jumper header function.
There is also an insertion point (E1) for connecting an external ground.
There are two versions of the M68MPB916R3: B and C. On the B version the
MCU is installed in a production socket on the board (Figure 2-1 shows the B
version board layout). On the C version the MCU is installed in a clam-shell
socket on the board (Figure 2-2 shows the C version board layout).

HARDWARE PREPARATION AND INSTALLATION
2-2 M68MPB16R3UM/D
CAUTION
Depending on your application, it may be necessary to cut the W2
wiring trace short (cut-trace short). Be careful not to cut adjacent
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.

fabricated jumper to return the jumper header to its factory default
state.

header number. Use a fabricated jumper to create a connection
between two of the three pins of the jumper header.

Configure the jumpers on jumper headers W6 and W7 to define which MCU is
evaluated/emulated; MC68HC16R1, MC68HC916R1, MC68HC16R3, and
MC68HC916R3. See paragraph 2.2.7 for more information.
2.2.1 Clock Select Header (W1)
Jumper header W1 connects the MCU external clock (EXTAL) pin to either an
on-board or external (target-system) clock source. The drawing below shows the
factory configuration: a fabricated jumper on pins 1 and 2. This configuration
selects the MPB on-board clock source; crystal oscillator inthe Y1 socket. (This
crystal provides for operation at the maximum rate the MCU allows via the
internal phase-locked loop or direct clock input.)
If you install the MPB in the active probe or directly on a target system, and use
the target system clock as the MPB clock, move the fabricated jumper to W1 pins
2 and 3. This connects the MCU EXTAL pin to the MAPI bus input pin. The
frequency of the external clock signal can be from 32 KHz to 16.78 MHz (or to
the maximum the MCU allows).

NOTE
You cannot drive the MPB clock circuit from an external source
(target system) with a discrete crystal. Ifyou use a target system
clock source to drive the MPB clock circuit, always use a logic-
driven clock such as a hybrid oscillator.

M68MPB16R3UM/D 2-5
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.
To use an external power source, remove the cut-trace short from W2 pins 1 and
2, then connect the external power source to W2 pin 2. Removal of the cut-trace
short isolates the MCU VDDA pin from the other MPB circuitry. Isolation lets
you connect a precision VDDA source for accurate 10-bit analog/digital (A/D)
generation. When connecting an external VDDA power supply to the MPB,
connect the power supply ground to insertion point E1. For more information on
A/D generation refer to the Analog-To-Digital Converter Reference Manual,
ADCRM/AD.

NOTES
If the cut-trace short has been cut, you must install a fabricated
jumper on W2 to return it to the factory configuration.
Jumper header W2 is not populated by the factory.

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.
To use an external VRH source, first place the fabricated jumper on W3 pins 2
and 3. Then connect the MCU VRH pin to the external VRH source. Each
configuration defines the best method for connecting the MCU VRH pin to the
external VRH source:
• MPB/MPFB – connect via the MPFB logic analyzer connector (refer to
Chapter 4 for the appropriate logic analyzer pin).
• MPB/MMDS1632 – connect via the VRH pin of the target MCU socket.
• MPB/Target System – connect via the VRH pin of the target system
MAPI bus.
Alternately, you may remove the jumper and wire-wrap directly to W3 pin 2.
Connecting directly to pin 2 is an option regardless of the configuration.

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.
To use an external VRL source, first place the fabricated jumper on W4 pins 2 and
3. Then connect the MCU VRL pin to the external VRL source. Each
configuration defines the best method for connecting the MCU VRL pin to the
external VRL source:
• MPB/MPFB – connect via the MPFB logic analyzer connector (refer to
Chapter 4 for the appropriate logic analyzer pin).
• MPB/MMDS1632 – connect via the VRL pin of the target MCU socket.
• MPB/Target System – connect via the VRL pin of the target system MAPI
bus.
Alternately, you may remove the jumper and wire-wrap directly to W4 pin 2.
Connecting directly to pin 2 is an option regardless of the configuration.

loop frequency synthesizer or the EXTAL input. The drawing below shows the
factory configuration: fabricated jumper on pins 1 and 2. This configuration
selects the MCU-internal phase-lock-loop frequency synthesizer as the clock. To
use the EXTAL input as the clock, place the fabricated jumper on 2 and 3.

2.2.6 Using a 32 KHz Clock
The factory installed crystal oscillator in location Y1 is rated at 4.194 megahertz.
You may change Y1 to change the clock speed of the MPB. The only other
oscillator you may install is 32 kilohertz. If you change Y1 to the slower value (32
KHz) you must replace the following capacitors and resistor (see diagram below):

Insertion point E1 is a plate through hole that lets you connect an external ground
to the MPB VSSA pin (refer to paragraph 2.2.2). Insert an external ground wire in
E1 and solder it into the plate through hole.
NOTE
Insertion point E1 is not populated by the factory.
