CHAPTER 1
GENERAL INFORMATION
1.1 INTRODUCTION
This manual provides general information, hardware preparation, installation
instructions, a quick start guide, and support information for the M68MPBF333
MCU Personality Board (MPB). The MPB is one component of Motorola’s
modular approach to MC68F333 Microcontroller Unit-based product
development. This modular approach lets you easily configure our development
systems to fit your requirements.
The MPB may be used in either the MMDS1632 Motorola Modular Development
System (MMDS) or the modular evaluation board (MEVB). The MEVB consists
of the M68MPFB Modular Platform Board (MPFB) and an MPB. 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 evaluated by
the MEVB. Both systems are invaluable tools for designing, debugging, and
evaluating MCU operation of the M68HC12, 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:
• M68MPBF333 MCU Personality Board (MPB)
• Plastic overlay for use with the MEVB – pin outs for the logic analyzer
connectors on the MPFB (specifically for the MC68F333 MCU)
• 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 four jumper headers (for which Table 2-2 is a quick reference
guide). You may re-configured 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. Figure 2-1
shows the location of the MPB jumper headers and the insertion point.
There are two versions of the M68MPBF333: 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 M68MPB333UM/D
NOTE
Verify that all socketed parts are seated in their sockets.
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.

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 32KHz 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.

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.

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.

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.

2.2.5 VSSA Insertion Point (E1)
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.

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. For more information about the MPFB
and MEVB system connections, refer to the M68MPFB1632 Modular
Platform Board User's Manual, M68MPFB1632/D. Chapter 3 contains
information to help you get started using yourMEVB.
CAUTION
Turn OFF MPFB power when installing the MPB on the MPFB or
removing the MPB from the MPFB. Sudden power surges could
damage MEVB integrated circuits.
To install the MPB on the MPFB (refer to Figure 2-3):
1. Inspect all connectors for bent or damaged pins.
2. Align the MPB reference mark with the MPFB reference mark.
3. Rotate the MPB until the four MAPI bus connectors on its bottom mate
with the MAPI bus connectors on the top of the MPFB. (There is only one
way to connect the MPB and the MPFB.)
4. Firmly press the MPB onto the MPFB.
CAUTION
Support the bottom side of MPFB when installing the MPB on the
MPFB. Excessive flexing of the MPFB could damage the printed
circuit.
