TMS 241 68HC12 Microcontroller Support Instruction Manual
Preface
This instruction manual contains specific information about the TMS 241
68HC12 microcontroller 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 microcontroller support packages on the logic
analyzer for which the TMS 241 68HC12 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 microcontroller 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 microcontroller support packages is included
with each product. Each logic analyzer has 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:
H Connecting the logic analyzer to the system under test
Manual Conventions
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:
The term “disassembler” refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
The phrase “information on basic operations” refers to online help, an
installation manual, or a basic operations of microcontroller supports user
manual.
In the information on basic operations, the term “XXX” or “P54C” used in
field selections and file names must be replaced with 68HC12. This is the
name of the microcontroller in field selections and file names you must use
to operate the 68HC12 support.
The term “SUT” (system under test) refers to the microcontroller-based
system from which data will be acquired.
TMS 241 68HC12 Microcontroller Support Instruction Manual

Preface
The term “logic analyzer” refers to the Tektronix logic analyzer for which
this product was purchased.
The 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.
68HC12 refers to all supported variations of the 68HC12 microcontroller,
including the 68HC812 and 68HC912 unless otherwise noted.
A tilde (~) following a signal name indicates that the signal is active low.
Logic Analyzer Documentation
A description of other documentation available for each type of Tektronix logic
analyzer is located in the corresponding module user manual. The manual set
provides the information necessary to install, operate, maintain, and service the
logic analyzer and associated products.

Getting Started
Getting Started
This chapter contains information on the TMS 241 microcontroller support, and
information on connecting your logic analyzer to your system under test.
Support Package Description
The TMS 241 microcontroller support package displays disassembled data from
systems based on the Motorola 68HC12 family of microcontrollers.
To use this support efficiently, you need to have the items listed in the information on basic operations as well as the following reference material:
68HC12 CPU12 Reference Manual, Motorola, First Edition, 1996,
CPU12RM/AD

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
For use with a TLA 700 Series, the TMS 241 support requires a minimum of
one 102-channel module.
For use with a DAS 9200 Series, the TMS 241 support requires a minimum of
one 96-channel module.

1–1
Getting Started
Requirements and Restrictions
Review the Specifications chapter in this manual as they pertain to your system
under test, as well as the following descriptions of other 68HC12 support
requirements and restrictions.
System Clock Rate. The 68HC12 microcontroller support can acquire data from
the 68HC12 microcontroller operating at speeds of up to 8 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.
Custom Clocking. The TMS 241 microcontroller support disassembler requires
Custom clocking in order to function correctly. Other clocking selections like
Internal and External may cause incorrect disassembly.
Hardware Reset. If a hardware reset occurs in your 68HC12 system during an
acquisition, the application disassembler may acquire an invalid sample.
Marking Cycles. The 68HC12 disassembler does not support the marking of
cycles.
Labeling P6434 Probes
The TMS 241 channel assignments follow the standard channel mapping and
labeling scheme for P6434 probes. Apply labels using the standard method as
described in the P6434 Mass Termination Probe Instructions.
DAS Mass Termination Interface (MTIF) Probes
The MTIF probes are already labeled since the probe sections for each probe are
permanent. The TMS 241 channel assignments follow the standard channel
mapping.
Channel Assignments
Channel assignments shown in Table 1–1 through Table 1–7 use the following
conventions:
1–2
H Unless otherwise indicated, all signals are required by the support.
H Channels are shown starting with the most significant bit (MSB) descending
to the least significant bit (LSB).
