TMS555 MPC565 Microcontroller Software Support
Getting Started
Getting Started
This section contains information on the TMS555 MP C565 microcontroller
support, and information on connecting your logic analyzer to your target
system.
Support Package Description
The TMS555 microcontroller support package displays disassembled data from
systems based on the PowerPC MPC565 and MPC555 microcontrollers.
The support package is also expected to work for MPC561/562, MPC563/564,
MPC566, and MPC556. The package does not support Code Compression.
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 TMS555 microcontroller support.
To use this support efficiently, you need the items listed in the information on
basic operations as well as the MPC555 User Manual, Motorola, Revision
October 2000, and the MPC565 Reference Manual Revision, October 2000.
Logic Analyzer Software Compatibility
The label on the microcontroller support floppy disk states which version of
logic analyzer software this support is compatible with.
Logic Analyzer Configuration
The TMS555 support requires a minimum of one 102-channel, 100 MHz
acquisition module.
Requirements and Restrictions
Review the electrical specifications in the Specifications section in this manual
as they pertain to your target system, as well as the following descriptions of
other MPC565 support requirements and restrictions.
Hardware Reset. If a hardware reset occurs in your MPC565 system during an
acquisition, the application disassembler might acquire invalid samples.
TMS555 MPC565 Microcontroller Software Support
1- 1
Getting Started
System Clock Rate. The support can acquire data from the MPC565 microcontroller operating at speeds of up to 56 MHz
1
. The MPC565 microcontroller support has been tested to 40 MHz for the nonburst mode and
20MHz for the burst mode.
Nonintrusive Acquisition. Acquiring microcontroller bus cycles is nonintrusive to
the target system. That is, the TMS555 MPC565 microcontroller does not
intercept, modify, or present back signals to the target system.
Channel Groups. Channel groups required for clocking and disassembly are the
addr Group, Data Group, Control Group, Chip_Select Group, Byte_Enable
Group, and ITR Group. The Misc group is not required for clocking and
disassembly.
The sample that was available for testing showed behavior inconsistent from
those described in the MPC565 device reference manual. The following
restrictions arise from these observations.
Refetching in Burst Mode. The processor refetches instructions while operating in
burst mode, even for noncontrol flow instructions (sequential instructions). This
mostly happens with multiple Read/Write instructions and floating point
instructions, but apparently is not related to the type of instructions only. Since
the disassembler has no knowledge or any indication of these refetches that are
made for normal sequential instructions, the instructions are parsed and
displayed multiple times.
1- 2
No Flush Information on the VF and VFLS Signals. The VF and VFLS lines do not
give the Flush Information as described in the device manual. This does not
affect the disassembly. Device behavior as described in the manual is untested;
the disassembly in Memory Image mode may be wrong if the behavior is
different.
Unexpected Messages on the VF Pins. If Data Show cycles are enabled, then the
messages “Indirect branch taken” and “VSYNC asserted” are displayed for the
VF signals even when there are no corresponding instructions. In Memory Image
mode, disassembly may be wrong because of these unexpected messages. This
problem does not occur if Data Show Cycles are disabled. If this problem occurs,
you cannot enable data show cycle while using Memory Image mode.

Timing Display Format
Getting Started
The support has a Timing Display Format file. It sets up the display to show the
following waveforms:
CLKOUT
addr
Data
RD/WR~
BURST~
TS~
BDIP~
TA~
BI~/STS~
AT2
BR~
BG~
BB~
TEA~
OE~
RETRY~
Byte_Enable
NOTE. The addr, Data and Byte_Enable are displayed in bus form.
Functionality Not Supported
Interrupt Signals. Not all of the interrupt signals are acquired by the TMS555
support software. Such signals are identified by the TMS555 support software
which displays the address for the interrupt service.
Alternate Bus Master. The disassembly does not process alternate bus master
transactions.
Code Compression. The package does not support code compression feature of
MPC556, MPC566, MPC562, and MPC564.
TMS555 MPC565 Microcontroller Software Support

Getting Started
Functionality Supported But Not Tested
The following features are supported, but are not tested:
H 8 and 16 bit port sizes
H Little Endian Mode
H Alternate Bus master
H Address Offset feature in Memory Image Mode
This support package may work for MPC561/562, and MPC563/564 microcontrollers, though it has not been tested.
Limitations Of The Support
The support has the following limitations when consecutive/ multireads and/or
consecutive branches are encountered. These limitations can be overcome by
using the Marking Options provided.
H Consecutive reads and multireads may be identified as fetches if AT[2]
(read/write indicator) is not enabled.
H The branch target embedded within the reads may be identified as READ.
This is expected only for Normal nonburst mode.
H Two branches within the instruction queue length may not be identified
properly. That is, the instructions are parsed, but the indication, whether
taken or not taken, may not be shown.
H The support identifies as not taken a conditional/indirect branch address that
is reached sequentially. For example, consider that there is a branch from
external to internal memory. Now the instructions are executed in the
internal memory. Consider that there is another branch in the internal
memory that branches back to the next sequential instruction of the external
memory. The support then identifies the branch of external memory as not
taken.
Connecting the Logic Analyzer to a Target System
You can use the channel probes, clock probes, and leadsets with a commercial
test clip (or adapter) to make the connections between the logic analyzer and
your target system.
1- 4
To connect the probes to MPC565 signals in the target system using a test clip,
follow the steps:
TMS555 MPC565 Microcontroller Software Support
Getting Started
1. Power off your target system. You do not need to power off the logic
analyzer.
CAUTION. To prevent static damage, handle the microprocessor, probes, and the
logic analyzer module 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 electricity from the test
clip.
CAUTION. To prevent permanent damage to the pins on the microprocessor, place
the target system on a horizontal surface before connecting the test clip.
Labeling P6434 Probes
3. Place the target system on a horizontal, static-free surface.
4. Use Tables 3--13 through 3--15 starting on page 3--7 to connect the channel
probes to MPC565 signal pins on the test clip or in the target system.
5. Use leadsets to connect at least one ground lead from each channel and the
ground lead from each clock probe to the ground pins on your test clip.
The TMS555 MPC565 software support package relies on the channel mapping
and labeling scheme for the P6434 Probes. Apply labels using the instructions
described in the P6434 Probe Instructions manual.
