Getting Started
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
To use the 68040 support, the Tektronix logic analyzer must be equipped with at
least a 102/136-channel module or a 96-channel module. The module must be
equipped with enough probes to acquire channel and clock data from signals in
your 68040-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 microprocessor
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 68040 support requirements
and restrictions.
System Clock Rate. The TMS 204 support product supports the 68040 microprocessor at speeds of up to 33 MHz
Hardware Reset. If a hardware reset occurs in your 68040 system during an
acquisition, the disassembler might acquire an invalid sample.
Cache Invalidation. Correct disassembly is not guaranteed for microprocessor
systems that run cache invalidations concurrent with burst cycles.
Dynamic Bus Sizing. When the Bus Size Control signals (BS16# or BS8#) are
asserted, the 68040 microprocessor allows the bus width to be changed for extra
cycles (when more than one cycle is required for a transaction). The disassembler
does not support changing the bus size for extra cycles. To keep the disassembler
synchronized, Use Mark Opcode as described in the Operating Basics chapter.

Data Reads and Writes. The dissassembler will not link data reads and writes with
the instruction which causes them.
Locked Bus Cycles. The dissasembler will not identify locked bus cycles.
Configuring the Probe Adapter
Disabling the cache makes all instruction prefetches visible on the bus so they
can be acquired and disassembled. The probe adapter contains a jumper you can
use to disable the 68040 cache.
With the cache jumper in the NORM position, the SUT controls the cache and
the CDIS~ signal is not affected.
With the cache jumper in the DIS position, the CDIS~ signal connects to a
332 Ω pull-down resistor on the probe adapter which disables the cache. You
should also cut or remove pin T5 from the protective socket on the underside of
the probe adapter to prevent contention with the driving signal.

processor 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 102/136-channel
module. Your probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microprocessor 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.
PGA Probe Adapter
To connect the logic analyzer to a SUT using a PGA probe adapter, 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 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
microprocessor 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 in Figure 1–2. This prevents the circuit board from flexing and the
socket pins from bending.
4. Remove the microprocessor from your SUT.

clip (or adapter) to make connections between the logic analyzer and your SUT.
To connect the probes to 68040 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.

Operating Basics
Setting Up the Support
This section provides information on how to set up the support. Information
covers the following topics:
HChannel group definitions
HClocking options
HSymbol table files
Remember that the information in this section is specific to the operations and
functions of the TMS 204 68040 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 disassembler automatically defines channel groups for the support product.
The channel groups for the 68040 support are Address, Data, Control, Intr,
Cache, and Misc.
The TMS 204 support offers a microprocessor-specific clocking mode for the
68040 microprocessor. This clocking mode is the default selection whenever you
load the 68040A support.
A description of how cycles are sampled by the module using the 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 clocking options for the TMS 204 support are: 68040 Address / Data Bus
Mode, and Alternate Bus Master Cycles.

Setting Up the Support
68040 Address / Data Bus
Mode
Alternate Bus Master
Cycles
Symbols
The 68040 has a multiplexed bus mode that supports the generation of a
multiplexed address/data bus. When used in this mode, the address and data bus
can be hard-wired together to form a single 32-bit address/data bus at the
microprocessor (CPU) with address and data information time-multiplexed on
the bus.
You select the 68040 address/data bus mode by selecting Multiplexed in the field.
The default selection is Non-Multiplexed.
NOTE. If you select the Multiplexed mode, you should remove the channels
connected to the data signals to reduce loading.
An alternate bus master cycle is defined as the 68040 giving up the bus to an
alternate device (a DMA device or another microprocessor). These types of
cycles are acquired when you select Included.
The TMS 204 support supplies one symbol table file. The 68040A_Ctrl file
replaces specific Control channel group values with symbolic values when
Symbolic is the radix for the channel group.
Table 2–1 shows the name, bit pattern, and meaning for the symbols in the file

Changing How Data is Displayed
There are fields and features that allow you to further modify displayed data to
suit your needs. You can make selections unique to the 68040 support to do the
following tasks:
HChange how data is displayed across all display formats
HChange the interpretation of disassembled cycles
HDisplay exception vectors
Optional Display
Selections
Marking Cycles
You can make optional display selections for aquire disassembled data to help
you analyze the data. You can make the selections in the Disassembly property
page (the Disassembly Format Definition overlay).
In addition to the common display options (described in the information on basic
operations), you can change the displayed data in the following ways:
HSpecify the starting address of the vector base register
HSpecify the size of the vector table
The 68040 support has two additional fields: Interrupt Table Address, and
Interrupt Table Size. These fields appear in the area indicated in the information
on basic operations.
Vector Base Register. You can specify the starting address of the vector base
register in hexadecimal. The default starting address is 0x00000000.
Vector Table Size. You can specify the size of the vector table in hexadecimal.
The default size is 0x400.
The disassembler has a Mark Opcode function that allows you to change the
interpretation of a cycle type. Using this function, you can select a cycle and
change it to one of the following cycle types:

HFlush (an opcode or extension that is fetched but not executed)
HAnything (any valid opcode, extension or flush)
HRead (marks a memory reference read as data)
Information on basic operations contains more details on marking cycles.
The disassembler can display exception vectors. You can select to display the
interrupt vectors for Real, Virtual, or Protected modes in the Interrupt Table field.
(Selecting Virtual is equivalent to selecting Protected.)
You can relocate the table by entering the starting address in the Interrupt Table
Address field. The Interrupt Table Address field provides the disassembler with
the offset address; enter an eight-digit hexadecimal value corresponding to the
offset of the base address of the exception table. The Interrupt Table Size field
lets you specify a three-digit hexadecimal size for the table.
You can make the selections in the Disassembly property page (the Disassembly
Format Definition overlay).
Interrupt cycle types are computed and cannot be used to control triggering.
When the 68040 microprocessor processes an interrupt, the disassembler displays
the type of interrupt, if known.

Probe Adapter Description
The probe adapter is a nonintrusive piece of hardware that allows the logic
analyzer to acquire data from a 68040 microprocessor 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.
Configuration
The probe adapter consists of a circuit board and a socket for a 68040
microprocessor. The probe adapter connects to the microprocessor in the SUT.
Signals from the microprocessor-based system flow from the probe adapter to the
channel groups and through the probe signal leads to the module.
All circuitry on the probe adapter is powered from the SUT.
The probe adapter accommodates the Motorola 68040, 68EC040, and 68LC040
microprocessors in a PGA package.
Disabling the cache makes all instruction prefetches visible on the bus so they
can be acquired and disassembled. The probe adapter contains a jumper you can
use to disable the 68040 cache.
With the cache jumper in the NORM position, the SUT controls the cache and
the CDIS~ signal is not affected.
With the cache jumper in the DIS position, the CDIS~ signal connects to a 332 Ω
pull-down resistor on the probe adapter which disables the cache. To prevent
contention with the driving signal, cut or remove pin T5 from the protective
socket on the underside of the probe adapter.

The channels in Table 3–11 are used only to clock in data. These channels are not
acquired or displayed. To acquire data from any of the signals shown in Table
3–11, you must connect another channel probe to the signal. This technique is
called double probing. An equals sign (=) following a signal name indicates that
it is already double probed.
How Data is Acquired
Custom Clocking
This part of this chapter explains how the module acquires 68040 signals using
the TMS 204 software and probe adapter. This part also provides additional
information on microprocessor signals accessible on or not accessible on the
probe adapter, and on extra acquisition channels available for you to use for
additional connections.
A special clocking program is loaded to the module every time you load the
68040 support. This special clocking is called Custom.
With custom clocking, the module logs in signals from multiple groups of
channels at different times when they are valid on the 68040 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 68040 bus cycle, no matter how many clock cycles are
contained in the bus cycle.

Clocking Options
The clocking algorithm for the 68040 support has several variations: Alternate
Bus Master Cycles Excluded, and Alternate Bus Master Cycles Included.
The 68040A software provides four modes for acquiring data. You can select the
clocking modes by selecting the appropriate fields in the Clock menu.
68040 Address/Data Bus Mode. The 68040 has a multiplexed bus mode that
supports the generation of a multiplexed address/data bus. When used in this
mode, the address and data bus can be hard-wired together to form a single 32-bit
address/data bus at the microprocessor (CPU) with address and data information
time–multiplexed on the bus.
You select the 68040 address/data bus mode by selecting Multiplexed in the field.
The default selection is Non-Multiplexed.

3–11
Specifications
NOTE. If you select the Multiplexed mode, you should remove the channels
connected to the data signals to reduce loading.
Alternate Bus Master Cycles Included. An alternate Bus Master Cycle is defined as
the 68040 giving up the bus to an alternate device (a DMA device or another
microprocessor). These types of cycles are acquired when you select Included.
Alternate Bus Master Cycles Excluded. Alternate Bus Master Cycles are not
acquired.
Alternate Microprocessor Connections
You can connect to microprocessor signals that are not required by the support so
you can do more advanced timing analysis. These signals might or might not be
accessible on the probe adapter board. The following paragraphs and tables list
signals that are or are not accessible on the probe adapter board.
Signals On the Probe
Adapter
For a list of signals required or not required for disassembly, refer to the channel
assignment tables beginning on page 3–5.
The probe adapter board contains pins for microprocessor signals that are not
acquired by the TMS 204 support. You can connect extra channels to these pins,
because they can be useful for general purpose analysis.
These channels are not defined in any channel group and data acquired from
them is not displayed. To display data, you will need to define a channel group.
