Support Description
This chapter provides information on the following topics:
H A description of the TMS 140 microcontroller support
H Logic analyzer software compatibility
H Your system under test requirements
H Support restrictions
H How to configure the probe adapter
H How to connect to the system under test (SUT)
The TMS 140 microcontroller support disassembles data from systems that are
based on the Intel 8031, 8032, 8051 and 8052 microcontrollers. The TMS 140
supports all 8031 and 8051 core-type microcontrollers that are compatible with
Intel MCS-51. The support runs on a compatible Tektronix logic analyzer
equipped with a 68/102/136-channel module or a 96-channel module.
Refer to information on basic operations to determine how many modules and
probes your logic analyzer needs to meet the minimum channel requirements for
the TMS 140 microcontroller support.
NOTE. The 8051 and 8052 have internal RAM and ROM. Only bus activity
outside the microcontroller is disassembled. Internal activity is not present on the
bus and cannot be disassembled.
Table 1–1 shows the microcontrollers and packages from which the TMS 140
support can acquire and disassemble data.

Getting Started
To use this support efficiently, you need to have the items listed in the information on basic operations as well as the 8-Bit Embedded Controller’s Manual, Intel
Inc., 1991
Information on basic operations also contains a general description of supports.
Logic Analyzer Software Compatibility
The label on the microcontroller support floppy disk states which version of logic
analyzer software the support is compatible with.
Logic Analyzer Configuration
To use the 8031, 8032, 8051 and 8052 support, the Tektronix logic analyzer must
be equipped with either a 68/102/136-channel module, or a 96-channel module at
a minimum. The module must be equipped with enough probes to acquire clock
and channel data from signals in your 8031, 8032, 8051 and 8052-based system.
Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.
Requirements and Restrictions
You should review the general requirements and restrictions of microcontroller
supports in the information on basic operations as they pertain to your SUT.
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 8031, 8032, 8051 and 8052
support requirements and restrictions.
System Clock Rate. The microcontroller support product supports the 8031, 8032,
8051 and 8052 microcontroller at speeds of up to 30 MHz
Hardware Reset. If a hardware reset occurs in your 8031, 8032, 8051 and 8052
system during an acquisition, the disassembler might acquire an invalid sample.
Internal RAM and ROM. The 8051 and 8052 are microcontrollers with internal
RAM and ROM. Only external bus activity (outside the microcontroller) is
disassembled. Internal activity is not present on the bus and cannot be acquired.

Specification at time of printing. Contact your PRISM sales representative for current
information on the fastest devices supported.
TMS 140 Microcontroller Support Instruction Manual
Interrupts and DMA Cycles. The disassembler handles interrupts and DMA cycles
as regular 8031, 8032, 8051 and 8052 cycles because there are no signals on the
8031, 8032, 8051 and 8052 microcontroller to indicate an interrupt or DMA
cycle. Therefore, interrupt and DMA cycles visible on the external bus are
disassembled as data reads and writes.
Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module.
Your SUT must also have a minimum amount of clear space surrounding the
microcontroller to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.
The channel and clock probes shown in this chapter are for a 68/102/136-channel
module. The probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microcontroller supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.
Getting Started
DIP Probe Adapter
Refer to the Replaceable Mechanical Parts chapter for part numbers of various
clip adapters and UPIK adapters you can use to connect to a 48-pin DIP and 44-,
68- or 84-pin PLCC packages.
To connect the logic analyzer to a SUT using a DIP probe adapter, follow these
steps:
1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.
CAUTION. Static discharge can damage the microcontroller, the probe adapter,
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
microcontroller and probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch any of the ground pins of the
probe adapter to discharge stored static electricity from the probe adapter.
3. Place the probe adapter onto the antistatic shipping foam to support the probe
as shown Figure 1–1. This prevents the circuit board from flexing and the
socket pins from bending.
4. Remove the microcontroller from your SUT.

5. Line up pin 1 on the microcontroller with the pin 1 indicator on the probe
adapter board.

Figure 1–3: Placing a DIP probe adapter onto the SUT
If your microcontroller is soldered to a circuit board and the probe adapter
provides pins to which you can connect a DIP clip, you will need to use the DIP
converter clip with the probe adapter.
One end of the converter clip connects to square pins on the probe adapter. The
other end connects to the microcontroller in your SUT. To connect the logic
analyzer to your SUT using a DIP probe adapter with a clip, refer to Figure 1–4
and follow these steps:
1. Follow steps 1 through 7 in the previous procedure.
2. Connect the cable end to the square pins on the probe adapter.
NOTE. The red strip along the side of the cable indicates that it connects to pin 1
on the probe adapter and pin 1 of the microcontroller.
3. Connect the clip end to the microcontroller.
NOTE. If you are having problems acquiring data, removing pins 18 (XTAL1) and
19 (XTAL2) from the DIP clip may restore proper operation.

You can use channel probes, clock probes, and leadsets with a commercial test
clip (or adapter) to make connections between the logic analyzer and your SUT.
To connect the probes to 8031, 8032, 8051 and 8052 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 microcontroller, 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
microcontroller.
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. Use Table 1–2 to connect the channel probes to 8031, 8032, 8051 and 8052
signal pins on the test clip or in the SUT.
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.

Operating Basics
Setting Up the Support
This section provides information on how to set up the support. Information
covers the following topics:
H Channel group definitions
H Clocking options
H Symbol table files
Remember that the information in this section is specific to the operations and
functions of the TMS 140 8031, 8032, 8051 and 8052 support on any Tektronix
logic analyzer for which it can be purchased. Information on basic operations
describes general tasks and functions.
Before you acquire and disassemble data, you need to load the support and
specify setups for clocking and triggering as described in the information on
basic operations. The support provides default values for each of these setups,
but you can change them as needed.
Channel Group Definitions
Clocking Options
The software automatically defines channel groups for the support. The channel
groups for the 8031, 8032, 8051 and 8052 support are Address, Data, and
Control. If you want to know which signal is in which group, refer to the
channel assignment tables beginning on page 3–4.
The TMS 140 support offers a microcontroller-specific clocking mode for the
8031, 8032, 8051 and 8052 microcontroller. This clocking mode is the default
selection whenever you load the 8031 support.
A description of how cycles are sampled by the module using the TMS 140
support and probe adapter is found in the Specifications chapter.
Disassembly will not be correct with the Internal or External clocking modes.
Information on basic operations describes how to use these clock selections for
general purpose analysis.
The TMS 140 support acquires all cycles. No clocking options are available.

Symbols
The TMS 140 support supplies one symbol table file. The 8031_Ctrl file replaces
specific Control channel group values with symbolic values when Symbolic is
the radix for the Control channel group.

Viewing Disassembled Data
You can view disassembled data in four different display formats: Hardware,
Software, Control Flow, and Subroutine. The information on basic operations
describes how to select the disassembly display formats.
NOTE. Selections in the Disassembly property page (the Disassembly Format
Definition overlay) must be set correctly for your acquired data to be disassembled correctly. Refer to Changing How Data is Displayed on page 2–6.
The default display format shows the Address, Data, and Control channel group
values for each sample of acquired data.
The disassembler displays special characters and strings in the instruction
mnemonics to indicate significant events. Table 2–2 shows these special
characters and strings, and gives a definition of what they represent.

Probe Adapter Description
The probe adapter is nonintrusive hardware that allows the logic analyzer to
acquire data from a microcontroller in its own operating environment with little
effect, if any, on that system. Information on basic operations contains a figure
showing the logic analyzer connected to a typical probe adapter. Refer to that
figure while reading the following description.
The probe adapter consists of a circuit board and a socket for a 8031, 8032, 8051
and 8052 microcontroller. The probe adapter connects to the microcontroller in
the SUT. Signals from the microcontroller-based system flow from the probe
adapter to the channel groups and through the probe signal leads to the module.
The probe adapter accommodates the Intel 8031, 8032, 8051 and 8052 microcontroller in a 40-pin DIP package. You can also use other clips and adapters with
the probe adapter to connect to the microcontrollers listed in Table 3–1.

These channels are used only to clock in data; they are not acquired or displayed.
To acquire data from any of the signals shown in Table 3–13, you must connect
another channel probe to the signal, a technique called double probing. An equals
sign (=) following a signal name indicates that it is already double probed.
TMS 140 Microcontroller Support Instruction Manual
How Data is Acquired
Specifications
This part of this chapter explains how the module acquires 8031, 8032, 8051 and
8052 signals using the TMS 140 software and probe adapter. This part also
provides additional information on microcontroller signals accessible on or not
accessible on the probe adapter, and on extra acquisition channels available for
you to use for additional connections.
Custom Clocking
A special clocking program is loaded to the module every time you load the 8031
support. This special clocking is called Custom.
With Custom clocking, the module logs in signals from multiple groups of
channels at different times as they become valid on the 8031, 8032, 8051 and
8052 bus. The module then sends all the logged-in signals to the trigger machine
and to the acquisition memory of the module for storage.
In Custom clocking, the module clocking state machine (CSM) generates one
master sample for each microcontroller bus cycle, no matter how many clock
cycles are contained in the bus cycle.
Acquiring Read cycles from External Program Memory. Lower address and data
buses are multiplexed on every version of the 8031, 8032, 8051 and 8052
microcontroller. The first sample point of program memory acquires only address
signals valid on the falling edge of ALE_B. The second sample point acquires
data and control signals on the rising edge of the PSEN_B~ signal.
Figure 3–2 shows the sample point and the master sample point.

Clocking Options
No variations are available for the clocking algorithm for the 8031, 8032, 8051
and 8052 microcontrollers.
Alternate Microcontroller Connections
You can connect to other signals that are not required by the support so that you
can analyze other signal activity in your system. These signals might or might
not be accessible on the probe adapter board. The following paragraphs and table
list signals that are not accessible on the probe adapter board.
For a list of signals required or not required for disassembly, refer to the channel
assignment tables beginning on page 3–4. Remember that these channels are
already included in a channel group. If you do connect these channels to other
signals, you should set up another channel group for them.

Extra Channels
The probe adapter does not provide access for the XTAL1 or XTAL2 signals.
Table 3–14 lists extra sections and channels that are left after you have connected
all the probes used by the support. You can use these extra channels to make
alternate SUT connections.
Channels not defined in a channel group by the TMS 140 software are logged in
with the Master sample point.
