Support Description
This chapter contains information on the TMS 220 microprocessor support, and
information on connecting your logic analyzer to your system under test.
The TMS 220 microprocessor support package disassembles data from systems
that are based on the Motorola MCF5202 and MCF5203 microprocessors.
The TMS 220 supports the MCF5202 and MCF5203 microprocessors in a
100-pin TQFP package.
To use this support efficiently, you need to have the items listed in the
information on basic operations as well as the following documents:
H Coldfire MCF5202/03 Specification, Motorola High Performance Embedded
Systems Division, 1995.
H MCF5200 Family Programmer’s Reference Manual, Motorola, 1995.
H MC68030 Enhanced 32-bit Microprocessor User’s Manual, Motorola, 1989.
H MC68040 32-bit Microprocessor User’s Manual, Motorola, 1989.
Logic Analyzer Software Compatibility
The label on the microprocessor support floppy disk states which version of logic
analyzer software the support is compatible with.
Logic Analyzer Configuration
For use with a TLA 700 Series, the TMS 220 support requires a minimum of
one 96-channel module.
For use with a DAS 9200 Series, the TMS 220 support requires a minimum of
one 96-channel module.
Requirements and Restrictions
You should review the general requirements and restrictions of microprocessor
supports in the information on basic operations as they pertain to your SUT.
TMS 220 MCF5202/03 Microprocessor Support Instruction Manual
1–1
Getting Started
You should also review electrical, environmental, and mechanical specifications
in the Specifications chapter in this manual as they pertain to your system under
test, as well as the following descriptions of other MCF5202/03 support
requirements and restrictions.
System Clock Rate. The TMS 220 support can acquire data from the
1
MCF5202/03 microprocessor at speeds of up to 33 MHz
.
Hardware Reset. If a hardware reset occurs in your MCF5202/03 system during
an acquisition, the disassembler may acquire an invalid sample.
Cache Invalidation. Correct disassembly is not guaranteed for microprocessor
systems that run cache invalidations concurrent with burst cycles. Data for these
cycles will not be disassembled and will be labeled as Cache Invalidation cycles.
Disabling the Internal Cache. To disassemble acquired data, you must disable the
internal cache. Disabling the cache makes all instruction prefetches visible on the
bus so they can be acquired and disassembled.
Big-Endian Byte Ordering. The disassembler always uses Big-Endian byte
ordering for instruction disassembly. Big-Endian byte ordering is when the most
significant data byte is located at the highest address.
Data Reads and Writes. The disassembler will not link data reads and writes with
the instructions which cause them.
Connecting to a System Under Test With A Probe Adapter
To connect the logic analyzer to a SUT using the probe adapter and test clip,
follow these steps:
1. Turn off power to your SUT.
It is not necessary to turn off the logic analyzer.

To connect the probe adapter assembly (probe adapter and test clip) to your SUT
follow these instructions:
7. Inspect the microcontroller on you SUT for bent or broken leads. Verify that
the leads on the microcontroller are clean and free from dirt, dust, or any
foreign material.
8. Inspect the pins of the test clip for bent or broken contacts. Verify that the
leads on the test clip are clean and free from dirt, dust or any foreign
material.
9. Verify that the locking devise on the test clip is not locked by turning the
locking device with a small screwdriver counter-clockwise.
10. Place the probe adapter onto the SUT as shown in Figure 1–3.
CAUTION. Failure to correctly place the probe adapter onto the microprocessor
might permanently damage all electrical components when power is applied.
Center the clip on the microprocessor and apply an equal downward force on all
four sides of the clip. It is important to keep the TQFP test clip parallel to the
microprocessor to avoid damage to the SUT or TQFP test clip.
Do not apply leverage to the probe adapter when installing or removing it.

Removing the Probe
Adapter from the SUT
CAUTION. The test clip was designed to be used on one and only one microprocessor. Because of the tight tolerances required for QFP test clip connectivity, the
test clip that attaches to the microprocessor has a soft plastic collar that
conforms to the unique shape of the target microprocessor.
To avoid faulty and unreliable connections, do not use the test clip on any other
microprocessor then the one it was originally connected to.
11. Lock the test clip to the microcontroller by turning the locking knob
clockwise with a small screwdriver.
CAUTION. The probe adapter board might slip off or slip to one side of the
microprocessor because of the extra weight of the probes. This can damage the
microprocessor
and the SUT. To prevent this from occurring, stabilize the probe
adapter by placing a non-conductive object (such as non-conductive foam)
between the probe adapter and the SUT.
To remove the probe adapter from the sut follow these steps:
1. Unlock the test clip from the microcontroller by turning the locking knob
counter-clockwise with a small screwdriver.
2. Gently lift and pull the probe adapter off of the microcontroller.

Getting Started
Connecting to a System Under Test Without A Probe Adapter
You can use the channel and clock probes and leadsets with a commercial test
clip (or adapter) to make connections between the logic analyzer and your SUT.
To connect probes to MCF5202/03 signals in the SUT using a test clip, follow
these steps:
1. Turn off power to your SUT. It is not necessary to turn off power to the logic
analyzer.
CAUTION. Static discharge can damage the microprocessor, the probes, or the
module. To prevent static damage, handle all of the above only in a static-free
environment.
Always wear a grounding wrist strap or similar device while handling the
microprocessor.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. If you are using a test clip, touch any of the
ground pins on the clip to discharge stored static electricity from it.
3. Table 1–1 through Table 1–8 shows the channel probes the MCF5202/03
signal pins on the test clip or in the SUT to connect to.
Use leadsets to connect at least one ground lead from each channel probe and
the ground lead from each clock probe to ground pins on your test clip.
NOTE. Since the microprocessor multiplexes address A31-A0 and data D31-D0
(as the AD31-AD0 signals), the D3:7-0, D2:7-0, D1:7-0 and D0:7-0 channel
probes do not need to be connected.
These channels are not considered to be extra channels, even though they are not
connected. Do not use them to make connections to other signals in your SUT.
4. Align pin 1 or A1 of your test clip with the corresponding pin 1 or A1 of the
MCF5202/03 microprocessor in your SUT and attach the clip.
