Preface
xTMS 440 SH-3 7708 Microprocessor Support
HThe term “logic analyzer” refers to the Tektronix logic analyzer for which
this product was purchased.
HThe term “module” refers to an acquisition module.
HThe term “HI module” refers to the module in the higher-numbered slot, and
the term “LO module” refers to the module in the lower-numbered slot.
HSH-3 refers to all supported variations of the SH-3 7708 microprocessor

HLogic analyzer software compatibility
HSupport restrictions
HHow to connect to the system under test (SUT)
HYour system under test requirements
HHow to apply power to and remove power from the probe adapter
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-chan-
nel 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 informa-
tion on basic operations as well as the following documents:
HSH7700 Series Programming Manual, Hitachi Micro Systems, Inc 8/8/95
ADE–602–096
HSH7708 Hardware User Manual, Hitachi Micro Systems, Inc 9/10/96

HSH–3 Series Memory Interfacing, Hitachi Micro Systems, Inc 11/22/96
Information on basic operations also contains a general description of support.
Contact Tektronix for the availability of SH-3 7702 Support.

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 reason-
able 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.
Default position for jumpers

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 surround-
ing 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.
