Support Package Description

The TMS 440 microprocessor support package displays disassembled data from a
system based on the Hitachi Micro Systems, Inc SH-3 7708 microprocessor.

The support runs on a TLA 700 Series logic analyzer equipped with a 102-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 440 microprocessor support.

A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Parts chapter.

To use this support efficiently, you need to have the items listed in the informa­tion on basic operations as well as the following documents:

Getting Started

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

To use the SH-3 7708 support, the TLA 700 Series logic analyzer must be
equipped with a 102-channel module at a minimum. The module must be
equipped with enough probes to acquire channel and clock data from signals in
your SH-3 7708-based system.

Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.

For the TLA 700 Series logic analyzer, the TMS 440 channel assignments follow
the standard channel mapping and labeling scheme for P6434 probes. Follow the
procedure to apply labels, using the standard method as described in the P6434
Mass Termination Probe Instructions.

Requirements and Restrictions

You should review the general requirements and restrictions of microprocessor
support packages in the information on basic operations as they pertain to your
SUT.

You should also review electrical, environmental, and mechanical specifications
in Specifications in this manual as they pertain to your system under test, as well
as the following descriptions of other SH-3 7708 support requirements and
restrictions.

System Clock Rate. The SH-3 7708 microprocessor support can acquire data from
the SH-3 7708 microprocessor operating at tested speeds of up to 60 MHz. This
specification is valid at the time this manual was printed. Please contact your
Tektronix Sales Representative for current information on the fastest devices
supported.

Channel groups. The following table lists the SH-3 signals not required by the
Clocking State Machine (CSM) or disassembler. SH-3 signals may be removed
from their default connections and reattached to other signals of interest. Channel
groups not required for clocking and disassembly are:

Signal name Section:channel

CKE C3–5

IOIS16~ C3–1

WAIT~ C0–2

IRQOUT~ C2–5

NMI~ C2–4
IRL0~ C0–3
IRL1~ C0–7
IRL2~ C3–0
IRL3~ C3–4

SUT Power. Whenever the SUT is powered off, remove power from the probe
adapter. Refer to Applying and Removing Power on page 1–9 for information on
how to remove power from the probe adapter.

Alternate Bus Master. Alternate bus master transactions are not processed in the
disassembly.

Data Disassembly . For correct data display disassembly turn off (disable) the
cache and the MMU address translation.

When the Address translation is enabled flushing could be incorrect (MMU page
breaks interpreted as address breaks).

Byte Invalidation. Invalid bytes cannot be dashed out for reads from SRAM/
PSRAM/ROM/PCMCIA interfaces.

Opcode Fetch/Data Read. SH-3 7708 does not provide a signal to distinguish
between “Data Read” and “Opcode Fetch”. The TMS 440 does make a reason­able estimate at looking a few sequences ahead at the address values yet in some
instances you may need to use the “Mark Opcode” function.

Configuring the Probe Adapter

There are six jumpers on the probe adapter. The default position for all six
jumpers is between pin 1 and pin 2 (See Figure 1–1). The custom clocking and
acquisition software-setup choices function correctly when the jumpers are in the
default position. Pin 2 of each jumper is connected to the logic analyzer through
the Mictor connectors. These six jumpers are intended for future use.

Connecting to a System Under Test With A Probe Adapter

Before you connect to the SUT (System Under Test), connect the probes to the
module. Your SUT must also have a minimum amount of clear space surround­ing the microprocessor to accommodate the probe adapter.

To connect the logic analyzer to a SUT using a probe adapter, follow these steps:

1. Turn off the power to your SUT. It is not necessary to turn off the logic

analyzer.

CAUTION. Static discharge can damage the microprocessor, the probe adapter,
the probes, and the module. To prevent static damage, handle these components
only in a static-free environment.

Always wear a grounding wrist strap, heel strap, or similar device while
handling the microprocessor and probe adapter.

5. Inspect the microprocessor on your SUT for bent or broken leads. Verify that

the leads on the microprocessor are clean and free from dirt, dust, or any
foreign material.

6. Inspect the pins of the test clip for bent or broken contacts. Verify that the

leads on the test clip are clean and free from dirt, dust or any foreign
material.

7. Verify that the locking devise on the test clip is not locked by pushing and

turning the locking device counterclockwise.

CAUTION. Failure to correctly place the probe adapter assembly onto the
microprocessor can permanently damage all electrical components when power
is applied.

Center the clip on the microprocessor and apply an equal downward force on all
four sides of the clip, slightly rocking the probe adapter in a clockwise circle.

Do not apply leverage to the probe adapter when installing or removing it.

9. Lock the test clip to the microprocessor by pushing and turning the locking

device clockwise.

CAUTION. The test clip was designed to be used on one and only one micropro­cessor. Because of the tight tolerances required for QFP test clip connectivity, the
test clip that attaches to the microprocessor has a soft plastic collar that
conforms to the unique shape of the target microprocessor.

To avoid faulty and unreliable connections, it is highly recommended that the test
clip is not used on any other microprocessor then the one it was originally
connected to.

The test clip has a manufacturer’s stated life expectancy of 8–10 connections.

Connecting to a System Under Test Without A Probe Adapter

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 SH-3 7708 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, and the
logic analyzer module. To prevent static damage, handle these components only
in a static-free environment.

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 it.

CAUTION. Failure to place the SUT on a horizontal surface before connecting the
test clip can permanently damage the pins on the microprocessor.

3. Place the SUT on a horizontal static-free surface.

4. Use Table 1–1 through Table 1–8 to connect the channel probes to

SH-3 7708 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.

Applying and Removing Power

A power supply for the SH-3 7708 probe adapter is included with this micropro­cessor support. The power supply provides +5 volts power to the probe adapter.

To apply power to the SH-3 7708 probe adapter and SUT, follow these steps:

CAUTION. Failure to use the +5 V power supply provided by Tektronix can
permanently damage the probe adapter and SH-3 7708 microprocessor. Do not
use any otherpower supply for the +5 V power supply.

1. Connect the +5 V power supply to the jack on the probe adapter. Figure 1–5

shows the location of the jack on the adapter board.

CAUTION. Failure to apply power to the probe adapter before applying power to
your SUT can permanently damage the SH-3 7708 microprocessor and SUT.

MMU address translation. The MMU address translation must be turned off for

proper disassembly. When Address translation is enabled Flushing could be
incorrect(MMU page breaks are interpreted as address breaks).

Channel Assignments

Channel assignments shown 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 shown starting with the most significant bit (MSB), descending

to the least significant bit (LSB).

H Channel group assignments are for all modules unless otherwise noted.
H A tilde (~) following a signal name indicates an active low signal.
H An equals sign (=) following a signal name indicates that it is double probed.
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.

Table 1–1 shows the probe section and channel assignments for the Address
group and the microprocessor signal to which each channel connects. By default
the Address channel group assignments are displayed in hexadecimal.
