Preface
This instruction manual contains specific information about the
TMS 562 MPC8260 microprocessor support package and is part of a set of
information on how to operate this product on compatible Tektronix logic
analyzers.
If you are familiar with operating microprocessor support packages on the logic
analyzer for which the TMS 562 MPC8260 support was purchased, you will
probably only need this instruction manual to set up and run the support.
If you are not familiar with operating microprocessor support packages, you will
need to supplement this instruction manual with information on basic operations
to set up and run the support.
Information on basic operations of microprocessor support packages is included
with each product. Each logic analyzer includes basic information that describes
how to perform tasks common to support packages on that platform. This
information can be in the form of online help, an installation manual, or a user
manual.
This manual provides detailed information on the following topics:
Manual Conventions
H Connecting the logic analyzer to the system under test
H Setting up the logic analyzer to acquire data from the system under test
H Acquiring and viewing disassembled data
This manual uses the following conventions:
H The term “disassembler” refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
H The phrase “information on basic operations” refers to online help, an
installation manual, or a user manual covering the basic operations of
microprocessor support.
H In the information on basic operations, the term “XXX” or “P54C” appearing
in field selections and file names must be replaced with MPC8260. This term
is the name of the microprocessor in field selections and file names you must
use to operate the MPC8260 support.

TMS 562 MPC8260 Microprocessor Support
Getting Started
Getting Started
This chapter contains information on the TMS 562 MPC8260 microprocessor
support and information on connecting your logic analyzer to your system under
test.
Support Package Description
The TMS 562 MPC8260 microprocessor support package displays disassembled
data from systems based on the Motorola MPC8260 microprocessor.
To use this support efficiently, refer to information on basic operations and the
following documents:
H MPC8260 PowerQUICC II User’s Manual March/1999 Rev. x.4
Logic Analyzer Software Compatibility
The label on the microprocessor support floppy disk states the version of logic
analyzer software the support is compatible with.
Logic Analyzer Configuration
The TMS 562 support requires a minimum of one 136-channel module.
Requirements and Restrictions
Review the electrical specifications in the Specifications chapter in this manual
as they pertain to your system under test, as well as the following descriptions of
other MPC8260 support requirements and restrictions.
Hardware Reset. If a hardware reset occurs in your MPC8260 system during an
acquisition, the application disassembler might acquire an invalid sample.
System Clock Rate. The MPC8260 microprocessor support can acquire data from
the MPC8260 microprocessor operating at speeds of 100 – 200 MHz. The
MPC8260 microprocessor support has been tested at the clock rate of 66 MHz.
The operating clock rate specifications were measured at the time of printing.
Contact your Tektronix sales representative for current information on the fastest
devices supported.
TMS 562 MPC8260 Microprocessor Support
1–1
Getting Started
Alternate Bus Master Cycles. The TMS 562 support acquires all bus cycles. The
disassembler can distinguish between the MPC8260 cycle and the alternate
master cycle by looking at the BG~ signal.
Nonintrusive Acquisition. The MPC8260 microprocessor will not intercept,
modify, or present signals back to the system under test.
Disabling the Instruction Cache. To display disassembled acquired data, you must
disable the internal instruction cache. Disabling the cache makes all instruction
prefetches visible on the bus so that they can be acquired and displayed
disassembled.
Disabling the Data Cache. To display acquired data, you must disable the data
cache. Disabling the data cache makes visible all loads and stores to memory on
the bus, including data reads and writes, so the software can acquire and display
them.
Address Translation. The address translation must be turned off for proper
disassembly.
1–2
TMS 562 MPC8260 Microprocessor Support
Functionality Not Supported
Interrupt Signals. Not all interrupt signals are acquired by the TMS 562 support
software. The interrupt signals that are acquired can be identified by the
TMS 562 support software by looking at the address that is displayed for the
interrupt service.
CPM Cycles. The communication processor module (CPM) is not supported.
60x Bus. Only the 60x bus is supported. The local bus of the processor is not
supported.
Nonintrusive Acquisition. The MPC8260 microprocessor will not intercept,
modify, or present signals back to the system under test.
Address Retry Cycles. Address Retry cycles are not supported.
Getting Started
Transfer Error Cycles. Transfer Error cycles are not supported.
SDRAM Address Multiplexing. SDRAM address multiplexing is not supported.
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.
To connect the probes to MPC8260 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 these components only in a staticfree environment. Static discharge can damage the microprocessor, the probes,
and the logic analyzer module.
Always wear a grounding wrist strap, heel strap, or similar device while
handling the microprocessor.

Channel Assignments
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 permanent 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 Table 1–1 through Table 1–8 to connect the channel probes to MPC8260
signal pins on the test clip or in the system under test.
5. 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.
Channel assignments listed in Table 1–1 through Table 1–8 use the following
conventions:
H All signals are required by the support unless indicated otherwise.
H Channels are listed starting with the most significant bit (MSB) and
descending to the least significant bit (LSB).
H Channel group assignments are for all modules unless otherwise noted.
H A tilde symbol (~) following the signal name indicates an active low signal.
H The module in the higher-numbered slot is referred to as the HI module and
the module in the lower-numbered slot is referred to as the LO module.
The TLA 704 logic analyzer has the lower-numbered slots on the top and the
TLA 711 logic analyzer has the lower-numbered slots on the left.

TraceAddr group Assignments. This is a synthesized group. This is used for
tracking the program flow when the cache is enabled. The user needs to use this
in conjuntion with the Trace Writes in Use disassembly option set to YES. This
group also uses the Trace Write Address value in the disassembly option which
needs to be entered by the user.
The user needs to enable the Branch Trace Exception by setting the BE field in
the MSR of MPC8260. When the Branch Trace Exception subroutine is
encountered, the SRR0 register will contain the target address of the branch
which was just executed. In the Trace Exception subroutine, the user would need
to write the value stored in SRR0 into the address specified in Trace Write
Address field. This needs to be a 32–bit write since the address is 32–bits.
Once this is done, the TraceAddr field would contain the value of the written data
which points to the target of the branch instruction. This is done by copying the
contents of the High_Data group into the TraceAddr group field. This can be
used for tracking the program flow even when cache is enabled.
NOTE. The Trace Write Address needs to be double word aligned, and located in
a 32–bit or a 64–bit memory region.
