TMS231 MC3X0 Microprocessor Support
Getting Started
Getting Started
This section contains information on the TMS231 MC3X0 microprocessor
support package and on connecting your logic analyzer to your system under test.
Support Package Description
The TMS231 MC3X0 microprocessor support package displays disassembled
data from systems based on the MCORE MC3X0 microprocessor.
To use this support efficiently, you need to have the items listed in the information on basic operations and M3X0 User Manual, M340 Specification v1.1,
11/20/98.
Information on basic operations also contains a general description of support.
Logic Analyzer Software Compatibility
The floppy disk label on the microprocessor support states which version of logic
analyzer software this support is compatible with.
Logic Analyzer Configuration
The TMS231 MC3X0 support requires a minimum of one 102-channel module.
Requirements and Restrictions
You should review the general requirements and restrictions of microprocessor
support packages as they pertain to your system under test.
You should also review electrical specifications in Specifications on page 3–1 as
they pertain to your system under test, as well as the following descriptions of
other MC3X0 support requirements and restrictions.
System Clock Rate
The operating speeds that the MC3X0
microprocessor are listed on Table 3–1. These specifications were valid at the
time this manual was printed. Please contact your Tektronix Sales Representative
for current information on the fastest devices supported.
support can acquire data from the MC3X0
TMS231 MC3X0 Microprocessor Support
1–1
Getting Started
NonIntrusive Acquisition
Disabling the Instruction
Cache
Acquiring microprocessor bus cycles is nonintrusive to the system under test.
That is, the MC3X0 support does not intercept, modify, or present signals back to
the system under test.
To display disassembled acquired data, you must disable the internal instruction
cache. Disabling the cache makes all instruction prefetches visible on the bus so
they can be acquired and displayed disassembled.
Limitation of the Support
8 Bit Mode
Multiple Instructions
In 8 bit mode if the Data comes in higher than 3 bytes D[31:24], D[23:16] and
D[15:8] it is not supported.
If multiple Branch instructions and MultiRead/Write instructions are entering the
fetch queue then the TMS231 MC3X0 support may not disassemble correctly. In
these cases the Mark Opcode Option can be used for correct disassembly.
Functionality Not Tested
H RIM mode
H 16 bit Upper and Lower modes
H 8 bit mode
Since the modes for RIM, 16 bit Upper and Lower, and 8 bit are not tested, even
though they are supported, the disassembly may be incorrect.
Connecting the Logic Analyzer to a System Under Test
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 system
under test.
1–2
TMS231 MC3X0 Microprocessor Support
Getting Started
To connect the probes to MC3X0 signals in the system under test using a test
clip, follow these steps:
1. Power off your system under test. It is not necessary to power off the logic
analyzer.
CAUTION. To prevent static damage, handle the microprocessor, the probes, and
the logic analyzer module components only in a static-free environment. Static
discharge can damage these components.
Always wear a grounding wrist strap, heel 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 the test clip.
CAUTION. To prevent damage to the pins on the microprocessor, place the system
under test on a horizontal surface before connecting the test clip.
3. Place the system under test on a horizontal static-free surface.
4. Use Tables 5–2 through 5–12 beginning on page 5–3 to connect the channel
probes to MC3X0 signal pins on the test clip or in the system under test.
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
The information in this section is specific to the operations and functions of the
TMS231 MC3X0 microprocessor support on any Tektronix logic analyzer for
which it can be purchased.
Before you acquire and display disassembled data, you need to load the support
and specify setups for clocking and triggering as described in the information on
basic operations in your logic analyzer online help. The microprocessor support
provides default values for each of these setups as well as user-definable settings.
Installing the Support Software
NOTE. Before you install any software, it is recommended that you verify that the
microprocessor support software is compatible with the logic analyzer software.
To install the TMS231 MC3X0 software on your Tektronix logic analyzer, follow
these steps:
1. Insert the floppy disk in the disk drive.
2. Click the Windows Start button, point to Settings, and click Control Panel.
3. In the Control Panel window, double-click Add/Remove Programs.
4. Follow the instructions on the screen for installing the software from the
To remove or uninstall software, close all windows, and then follow the above
instructions and select Uninstall.
Channel Group Definitions
The software automatically defines channel groups for the support. The channel
groups for the TMS231 MC3X0 support are Address, Data, Control, Chip Select,
Proc_Mode, Interrupt, and Misc. The channel group tables begin on page 5–1.
