CHAPTER 1
INTRODUCTION
1.1 OVERVIEW
This chapter is an overview of the M68ICS05P In-Circuit Simulator Kit components and a Quick
Start guide to setting up a development project.
The Motorola M68ICS05P In-Circuit Simulator Kit is a development toolkit for designers who
develop and debug target systems that incorporate M68HC705P6/P9 Microcontroller Unit
(MCU) devices. The toolkit contains all of the hardware and software needed to develop and
simulate source code for and program the Motorola M68HC705P microcontrollers.
Together, the M68ICS05P printed circuit board (pod) and the ICS05PW software form a
complete simulator and non-real-time I/O emulator for a M68HC705P6/P9 device. When you
connect the pod to your PC and your target hardware, you can use the actual inputs and outputs
of the target system during simulation of code.
Use the M68ICS05P toolkit with any IBM-Windows 3.x or Windows 95-based computer with a
serial port.
1.2 TOOLKIT COMPONENTS
The complete M68ICS05P toolkit contains:
• Hardware:
− The M68ICS05P in-circuit simulator pod.
− A sample M68HC705P9 EEPROM MCU.
− A 28-pin DIP target emulation cable.

POD INSTALLATION
M68ICS05POM/D 2-1
CHAPTER 2
POD INSTALLATION
2.1 OVERVIEW
This chapter explains how to install the hardware components of the M68ICS05P in-circuit
simulator on your host PC in both interactive and standalone modes.
When the M68ICS05P pod is connected to the serial port of a host PC, you can use the actual
inputs and outputs of your target system during simulation of your source code. W hen the pod is
not connected to the PC, you can use the ICS05PW software as a standalone simulator.
2.2 INSTALLING THE M68ICS05P POD
Before beginning, locate these pod components:
• Hardware reset switch S3
• Power On switch S1
• 9-pin RS-232 serial connector P2
• 9 Volt Input Circular connector P1
To install the M68ICS05P Pod:
1. Connect the M68ICS05P pod to the serial port of your computer: attach the supplied
9-pin serial cable to the connector on the M68ICS05P board and attach the other end
to the host PC’s serial port.
2. Connect the 9-volt power supply: attach the power supply plug to the circular power
connector on the M68ICS05P pod and plug the power supply into a surge protection
device or wall outlet.
3. To run the ICS05PW software with actual input and output from the target device,
connect the M68ICS05P pod to the 28-pin DIP socket on the target board using the
28-pin ribbon cable included in the M68ICS05P kit. When this connection is
established and the pod and target system are started up, the target system will
provide inputs to and accept output from the ICS05PW software.

SOFTWARE INSTALLATION AND INITIALIZATION
M68ICS05POM/D 3-1
CHAPTER 3
SOFTWARE INSTALLATION AND INITIALIZATION
3.1 OVERVIEW
This chapter how to install and initialize the ICS05PW software.
3.2 THE ICS05PW SOFTWARE COMPONENTS
The ICS05PW software consists of the following components:
• WINIDE.EXE: the Windows Integrated Development Environment editor
• CASM05W.EXE: the 68HC05 Cross Assembler
• ICS05PW.EXE: the in-circuit Simulator, optimized for the HC05Px-family Motorola
microcontrollers
3.2.1 The WinIDE Editor
The WinIDE editor is a text editing application that lets you use several different programs from
within a single development environment. Use the WinIDE editor to edit source code, launch a
variety of compatible assemblers, compilers, debuggers, or programmers, and configure the
environment to read and display errors from such programs.
If you select error detection options in the Environment Settings dialog, the WinIDE editor will
highlight errors in the source code, and display the error messages from the compiler or
assembler in the editor.
To debug source code in the WinIDE code window, load compatible source-level map files. You
can configure the CASM05W to produce such map files as an output.
Because the WinIDE editor is modular, you may, for example, choose to substitute a third party
C-compiler or other assembler for the CASM05W cross assembler provided in the toolkit.
3.2.2 CASM05W
The CASM05W is a cross assembler that creates Motorola S19 object files and MAP files from
assembly files containing 68HC05 instructions.
Freescale Semiconductor, I
Freescale Semiconductor, Inc.

nc...
SOFTWARE INSTALLATION AND INITIALIZATION
M68ICS05POM/D3-2
The CASM05W assembler has the same functionality as the DOS version of the assembler,
optimized to take advantage of the Windows graphical environment. Using the assembler in
conjunction with the WinIDE editor, you can edit standard ASCII files (such as the .ASM
assembly files), and use menu options and toolbar buttons to call other customized assemblers,
compilers, or debuggers. The resulting environment can allow assembled files to be downloaded
and tested while the original source code is modified and assembled, all without leaving the
WinIDE editing environment.
Paragraph 5-5 gives additional information about assembler options and how to use them.
3.2.3 ICS05PW
The ICS05PW is a simulator for HC705P9 and HC705P6 microcontrollers that can get inputs
and outputs (I/O) for the device when the external M68ICS05 pod is attached to the host
computer. If you want to use I/O from your own target board, you can attach the M68ICS05 pod
to your board through the extension cable that comes with the toolkit. You can also program
HC05P devices using the ICS05P board and ICS05PW software.
You can start or move to the ICS05PW in-circuit simulator software from the WinIDE editor.
The ICS05PW software can also be started using standard Windows techniques and run
independently of the WinIDE editor.
The IC S05P W simulator accepts standard Motorola S19 object code files as input for object code
simulation and debugging. If you are using a third party assembly- or C-language compiler, the
compiler must be capable of producing source-level map files to allow source-level debugging.
3.3 INSTALLING THE ICS05PW SOFTWARE
The ICS05PW software is on a single 3.5 ″ diskette containing a setup program that automatically
installs the software on your hard drive.
3.3.1 Installation Steps
To install the software on your host computer’s hard drive, follow these steps:
1. Insert the ICS05PW diskette into the 3.5-inch disk drive.
For Windows 3.x: in the Program Manager, select Run from the File menu.
For Windows 95: from the Start Menu, select the Run option.
2. In the Run dialog, enter Setup (or click the Browse button to select a different drive
and/or directory) and press OK.

4.4.5 Using Markers
Markers provide a convenient way to mark multiple points in a file for navigating between
frequently visited locations while you are editing. You can set as many as 10 markers in source
files in the WinIDE editor. A marker appears in the file as a small button labeled with the marker
number.
When you save the project, the WinIDE editor saves the markers for all open edit files as well, so
that when you open the project again, the markers are still set.
To set a marker anywhere in the file:
1. Place the cursor on the line where you want the marker to be.
2. Press CNTL + SHIFT + N, where N is a value from 0 to 9 indicating the marker
number. A marker appears at the far left of the line.
To move to a marker, press CNTL + N, where N is denotes a marker number between 0 and 9.
This feature is useful if you are editing a large file.
Markers can also be set, changed, navigated to, or cleared using options on the Edit shortcut
menu (Figure 4-3). Open the Edit shortcut menu by clicking the right mouse button in any edit
window.
Figure 4-3. Edit Shortcut Menu
To set or clear a marker using the Edit shortcut menu options:
1. With the cursor in any editing window, click the right mouse button to open the
shortcut menu.
2. Position the cursor on the line where the marker should appear. Click the right mouse
button to display the shortcut menu.
3. Click the Toggle Marker 0-9 option to open the list of markers.
4. Click once on the marker to toggle. When the marker number is checked, it is toggled
on; when the marker number is unchecked, it is toggled off.

Figure 4-4. Marker Sub-menu
You can execute many ICS05PW menu options using either keyboard commands or toolbar
buttons. For example, to move to a marker, press the Ctrl + Shift + N key combination, where N
is the marker number).
4.5 COMMAND-LINE PARAMETERS
The WinIDE editor lets you specify command line options to pass to each executable program.
The name of the currently edited file, or some derivative thereof, can be passed within these
options. To pass the current filename, specify a parameter %FILE%. The WinIDE editor will
substitute this string with the current filename at execution time. You may also change the
extension of the passed filename, by specifying it within the %FILE% parameter. For example,
to specify an .S19 extension on the current filename the user would specify a %FILE.S19%
parameter.
For example, if the current filename being edited is MYPDA.ASM:
Parameters specified Parameters passed to
program
%FILE% S L D MYPDA.ASM S L D
%FILE. S19% 1 @2 MYPDA.S19 1 @2
Although it is by default the currently edited filename that is used in the %FILE% parameter
substitution, the environment can be configured always to pass the same filename. Do this by
checking the Main File option in the Environment Settings dialog’s General Options tab. This

4.9.2 Redo
Choose Redo to restore the most recently undone action in the active window.
The Redo option restores actions undone or reversed by the Undo option, in ascending order, that
is, last action first. Reversible changes to the window’s contents accumulate in the window’s
undo stack. Once a change has been reversed using the Undo option, the change can be reversed,
using the Redo option When no more changes remain (that is, the top of the Redo stack is
reached) the Redo option is disabled.
Some commands are not reversible: they do not contribute to the undo stack and therefore cannot
be redone. For instance, since reversible actions are local to each source window, opening a new
window is an action that cannot be undone using the Undo command, or redone using the Redo
command.
NOTE
The Redo option is active only if you have used the Undo option to
modify the contents of the active source window.
Alternative: Type Shif t + Ctrl + Z. This is the keyboard equivalent to selecting the Edit - Redo

information. If there is an open project, the project file’s environment settings are read and used
instead. This lets you have different environment configurations for different projects.
Environment information stored in the WINIDE.INI file includes:
• If a project is open, its name
• Current font information
• Current source directory and project directory paths
• The preferences and options you set in the Environment Settings dialog tabs,
including:
− General Environment options
− General Editor options
− Executable options for assembler, debugger, compiler, and programmer
To choose an environment option, click once on the Environment menu title (Figure 4-10) to open the

• %FILE% Parameter passed to executable programs is: The %FILE% parameter
specifies what is passed on the command line in place of the %FILE% string. You
may specify the %FILE% string as a command line parameter for executable
programs launched from within the WinIDE editor.
− Currently edited filename: Select this option to use the name of the current
active file (the window with focus) as the %FILE% parameter substitution.
− Main Filename: Select this option to use the filename in the Main filename
edit box as the %FILE% parameter substitution.
NOTE
If you are using include files, you must enter the full pathname of
the file containing the included files in the Main filename edit box.

programs which you can launch from the WinIDE editor offer the option to save all
open editor files before the executable is launched.
− Give user option to save each file: Select this option if you want to be
prompted to save each modified file before the external program is launched.
If you do not select this option, the external program runs without asking for
your confirmation. The result may be that an external program runs while
modified files exist in the editing environment, a circumstance that may be
undesirable and lead to incorrect results.

Figure 4-14. Environment Settings Dialog:
General Editor Tab
• General Options
− Auto-Indentation: Select this option to place the cursor in the column of the
first non-space character of the previous line when the Enter key is pressed. If
this option is not checked, the cursor goes to the first column. For ex ample, if
the current line begins with two tab spaces, pressing the Enter key will begin
the next line with two tab spaces, aligning the new line under the first text of
the previous line.
− Create Backup: Select this option to create a backup file whenever a file is
saved. The WinIDE editor will copy the current disk version of the file (the
last save) to a file of the same name with the .BAK extension, then save the
current edited copy over the editing filename. The default (and recommended)
setting for this option is "on," giving you the option to return or review the
previous version of the file. If you do not select this option, the currently
edited file will be saved, but no backup will be made.
• Word Wrap
− Wrap to Window: Select this option to have the cursor to wrap to the left
when it reaches the far right side of the window. This lets you see all the tex t

in the file, without scrolling the line. If you do not select this option, text
wraps only when you press the Enter key.
− Wrap to Column: Select this option to wrap text to the left side when the
cursor reaches a specified column. This lets you see all the text in the file,
without scrolling the line. Set the column number at which text wrapping
should occur in the edit box to the right of this option.
− Word Wrap OFF: Select this option to turn text wrapping off. To view or edit
text, which does not fit horizontally in the window, use the scroll controls. In
general, this option should be on when you are writing or editing code.
• Tab Settings
− Fixed Tabs: Select this option to use spaces to emulate tabs: pressing the tab
key inserts a number of spaces to bring the cursor to the position of the next
tab stop. Changing the tab size affects only future tab spacings. Past tabs
remain unchanged.
− Real Tabs: Select this option to use actual tab charact ers: pressing the tab key
insets a tab character. The tab character is displayed as a number of spaces
determined by the tab size, but is really a tab character. Changing the tab size
affects the display of all tabs in the file, present and future.
− Smart Tabs: Select this option to enable smart tabs:
If the previous line contains text, pressing the tab key advances the
cursor to the same column as the beginning of the next character group
on the previous line.
If the previous line does not contain text, smart tabs behave as fixed
tabs.
− Tab Size: Enter the number of spaces in a tab. This setting affects how all tabs
operate: fixed, real, or smart tabs. This number is the default display size of all
tab characters, and the size in spaces of a tab in bot h fix ed and smart m odes. If
the tab size is N, the tab stops are at 1, N+1, 2N+1, 3N+1, and so on.
4.10.5.3 Assembler/Compiler Tab
In addition to running an external compiler, you may need to run other ex ternal programs such as
third party programmers, debuggers, or simulators. The WinIDE editor lets you configure as
many as three external programs: two general-purpose programs and one compiler. Use the
settings on the Assembler/Compiler tab of the WinIDE Environment Settings dialog to set up
external programs.
Click the Assembler/Compiler tab heading in the Environment Settings dialog (Figure 4-15) to
bring the tab to the front. Use the options on this tab to change the settings and parameters for the
assembler or compiler path and type, and specify output, listing, and assembly preferences.

• EXE Path: Enter the full path and executable name of the compiler in the text box.
The extensions EXE/COM/BAT are legal. For a DOS executable or BATch file, you
may want to creat e a PIF file to prevent the screen from changing video modes when
the executable runs.
Figure 4-15. Environment Settings Dialog:
Assembler/Compiler Tab
• TYPE: Click on the downward-pointing arrow to the right of the Type list box to
display the compiler types. Click on the compiler type to select it. The options in the
Assembler/Compiler tab change according to the compiler type chosen:
− If you select the P&E compiler, a number of compiler options are available.
− If you select a non-P&E compiler, options lets you specify the parameters to
pass the compiler.
• Output Control: These options specify the output files that the assembler will create:
− Output S19 Object: Select this option to have the assembler output an S19
object file. The S19 object file contains the compiled instructions from the
program assembled. The output S19 file has the same name as the assembly
file, but with the .S19 extension. Appendix A: S-Record Information gives
more information about the S19 file format.
− Output Debug File: Select this option to have the assembler produce a debug
.MAP file. The debug .MAP file contains symbol information as well as line
number information for source level debugging from the program assembled.
The output debug file has the same name as the assembly file, but with the
.MAP extension.
− Output Listing File: Select this option to have the assembler produce a listing
file. The listing file shows the source code as well as the object codes that
were produced from the assembler. Listing files are useful for debugging, as

they let you see ex actly where and how the code assembled. The output listing
file has the same name as the assembly file, but with the .LST extension.
• Listing Options: The following options specify how the assembler generates the
listing file.
− Show Cycles in Listing: Select this option to include cycle information for
each compiled instruction in the listing (.LST) file. View the cycle information
to see how long each instruction takes to execute. The cycle count appears to
the right of the address, enclosed in brackets.
− Expand Includes in Listing: Select this option to expand all include files into
the current listing file. This lets you view all source files in a main listing file.
If this option is not checked, you will see only the $Include statem ent for each
included file, not the source file.
− Expand Macros in Listing: Select this option to expand all macros into the
listing file: each time the macro is used, the listing will show the instructions
comprising the macro. If you do not select this option, you see only the macro
name, not its instructions.
• Assembly Preferences
− Show Assembler Progress: Select this option to display a popup window
showing the current assembly status, including:
• The pass the assembler is currently on
• The file that is currently being assembled
• The line that is currently being assembled
If this option is not checked, you must wait for the assembly result to be
displayed on the status bar at the bottom of the environment window.
− Wait for Assembler Result: Select this option and the Show Assembler
Progress option to cause a progress window displaying the assembly result to
stay up when assembly is done. The assembly result window will remain until
you dismiss it by clicking the OK button. In general, do not select this option,
as the assembler results are shown in the status bar at the bottom of the
WinIDE window.
− Save files before Assembling: Select this option to save all open files to disk
before you run the assembler. This is important because the
assembler/compiler reads the file to be compiled from the disk, not from the
open windows in the WinIDE editor. If you do not save the file before
assembling it, the assembler will assemble the last saved version. In general,
you should leave this option checked.
− Sound Bell on Error: Select this option to have the assembler beep if it
encounters an error.

• Other Assembler/Compi ler: If you choose Other Assembler/ Compiler . . . from the
Type list, the WinIDE editor offers these additional options:
− Options: Enter the options to pass to the compiler on the command line. Such
options generally consist of switches that instruct the compiler, and a
filename. Enter the %FILE% string in the command line to insert either the
current filename or the filename specified in the Main Filename option in the
EXE Path text box of the General Environment tab options (Figure 4-13).
− Confirm command line: Select this option to display a window describing the
executable you want to run, and the parameters that you want to pass to the
executable, just before the assembler/compiler is run. This gives you the
option to cancel the assemble/compile, continue as described, or modify
parameters before you continue with the assembly. If you do not select this
option, the assembler/compiler runs without prompting you to confirm
parameters.
− Recover Error from Compiler: Select this option to have the WinIDE editor
attempt to recover error/success information from the assembler/compiler, and
open the file with the error line highlighted (and displayed in the status bar)
when an error is encountered. For this feature to work, the Error Filename and
Error Format options must also be set in this tab. If this option is not checked,
the WinIDE editor will not look for a compiler result and will not display the
results in the status bar.
− Wait for compiler to finish: Select this option to have the WinIDE editor
disable itself until the compiler terminates. You must select this option for the
editor to attempt to recover error/success information from the assembler/
compiler. Further, turning this option on prevents you from running external
programs from the editor that may require compilation or assembly results. If
you do not select this option, the editor starts the assembler/compiler, and
continues, letting Windows’ multitasking capabilities take care of the program.
− Save files before Assembling: Select this option to save all open files to disk
before the running the assembler. This can be very important since the
assembler/compiler reads the file to be compiled from the disk and not from
the memory of the WinIDE editor. If the file being assembled isn’t saved, the
assembler or compiler will assemble the last saved version. For this reason,
you should leave this option checked.

• Error Format: Click the down arrow to the right of the Error Format list box to
display the list of error formats (Figure 4-16). If the WinIDE editor is to attempt to
read back an error from a compiler, it must understand the error syntax. This option
lets you select an error format from a list of supported formats. If the Recover Error
from compiler option is checked, and the filename specified in the Error Filename
text box is found, the editor parses that file from end to beginning looking for the
error. If the editor finds an error, it opens the file, highlights the error line, and
displays the error in the status bar.
Figure 4-16. Error Format List
• Error Filename: Enter the filename to which the editor pipes the compiler/assembler
error output. Some compilers provide a switch for piping error output to a file; others
require that you handle this manually. As most compilers are DOS-based, you can
create a batch file into which to pipe the output. For example:
COMPILER OPTIONS > ERROR.TXT
This batch file creates the file ERROR.TXT and sends the assembler/compiler output to
that file. Most C-compilers require a batch file to run the compiler through its various
steps (compiling, linking), to which you may add a pipe for error output.
Once the environment reads this error file, the WinIDE editor displays the results, and
the deletes the error file. If you want to keep a copy of the file, you must add such
instructions to the batch file.

CHAPTER 5
ASSEMBLER INTERFACE
5.1 OVERVIEW
This chapter describes the operation of the CASM05W assembler, including methods for
interfacing with the assembler from the WinIDE, setting assembler options and directives,
generating and using output files and formats, and understanding assembler-generated error
messages.
In order to be used in the target microcontroller CPU, the source code for your program must be
converted from its mnemonic codes to the machine code that the target CPU can execute. The
CASM assembler program accomplishes this by reading the source code mnemonics and
assembling an object code file that can be programmed into the memory of the target
microcontroller. Depending on the parameters that you specify for the assembler, other
supporting files can be produced that are helpful in the debugging process.
When you click on the Assemble/Compile file button in the WinIDE, the CASM cross assembler
is activated to process the active file in the WinIDE main window according to the parameters
you have entered. In addition to two kinds of object code files, you may choose to have the
assembler produce .MAP and/or .LST files as well.
Listing files show the original source code, or mnemonics, including comments, as well as the
object code translation. You can use this listing during the debugging phase of the development
project. It also provides a basis for documenting the program.

5.4 ASSEMBLER OUTPUTS
5.4.1 Object Files
If you specify an object file in the command-line in the Program Item Properties in Windows,
using the S or H parameters, the object file is created during assembly. The object file has the
same name as the file being assembled, with the extension .HEX or .S19, depending on the
specification given:
• Motorola uses the S-Record 8-bit object code file format for object files. For more
information, see Appendix A: S-Record Information.
• .HEX is the Intel 8-bit object code format.
In either case, t he object code fil e produced by the C ASM 05W assem bler i s a tex t file cont aining
numbers that represent the binary opcodes and data of the assembled program. This object code
file can be sent to the MCU using a programmer or bootstrap program, at which time it is
converted to the binary format required by the target CPU.
The object filename depends on the choice made in the command line of the Windows Program
Item Properties. By default, the object filename is that of the file being assembled, with the
proper object file format extensions. An existing file with the same name will be overwritten.
5.4.2 Map Files
If you specify a map file using the D parameter, the P&E Debug .MAP file is created during the
assembly. P&E Microcomputer products (such as the MMDS and the MMEVS) use these map
files during the source-level debugging process.
Map files contain the directory path information under which they are created, and cannot,
therefore, be moved to a new directory. If you must use the map file from a different directory,

place the file in the new directory and reassemble, using the map file option D in the Windows
command line.
5.4.3 Listing Files
If you specify a listing file using the L parameter in the Windows command line, a file with the
same name as the file being assembled and the extension LST can be produced by the assembler.
This file serves as a program listing showing the binary numbers that the CPU needs, alongside
the assembly language statements from the source code.
For more information about using the assembler listing directives, see the summary of Assembler
Directives in Table 5-2, beginning in paragraph 5-6.
5.4.4 Files from Other Assemblers
It is possible to use files produced by another assembler with the CASM05W assembler,
providing they are properly prepared before using. To prepare a source file from a third-party
assembler for use with the CASM05W, follow these steps:
1. Precede all comments by a semicolon.
2. Using the WinIDE (or other editor) global search and replace command, change any
assembler-specific directives, listing directives, pseudo operations, etc., as required to
create a file which is compatible with the CASM05W. Remember that assembler
directives must begin with the characters $, /, ., or #, and must begin in column 1.
3. If necessary, use the BASE directive to change the default base for the operands
(CASM05W defaults to hexadecimal base).
5.5 ASSEMBLER OPTIONS
The CASM05W assembler supports all Motorola opcode mnemonics in the command set. For
descriptions of the debugging commands, see Chapter 7, ICS05PW Debugging Command Set.
NOTE
Opcodes mnemonics cannot start in column one. If a label begins
the line, th ere must be at least one space between t he label and t he
opcode.

5.5.1 Operands and Constants
Operands are addresses, labels, or constants, as defined by the opcode. Assembly-time arithmetic
is allowed within operands. Such arithmetic may use these operations:
* multiplication
/ division
+ addition
- subtraction
< left shift
> right shift
% remainder after division
& bitwise and
| bitwise or
^ bitwise xor
Operator precedence follows algebraic rules. You may use parentheses to alter precedence. If
your expression contains more than one operator, parenthesis, or embedded space, you must put
the entire expression inside braces ( { } ).
jmp start ;start is a previously defined label
jmp start+3 ;jump to location
start + 3
jmp (start > 2) ;jump to location
start divided by 4
Constants are specific numbers in assembly-language commands. The default base for constants
is hexadecimal, but you may change the default using the Change Base Address dialogs for the
Memory and Code windows. To temporarily override the default base, use either the appropriate
prefix or suffix (Table 5-1), but not both.
The assembler also accepts ASCII constants. Specify an ASCII constant by enclosing it i n single
or double quotes. A character ASCII constant has an equivalent value: ‘A’ is the same as 41H.
An example of a string constant is:
db “this is a string”

5.5.2 Comments
Use semicolons to delineate comments. A comment may start in any column and runs until the
end of its line. Additionally, if any line has an asterisk (*) or semicolon (;) in column 1, the entire
line is a comment.
5.6 ASSEMBLER DIRECTIVES
Assembler directives are keywords that control the progress and the modes of the CASM05W
assembler. To invoke an assembler directive, enter a /, #, or $ as the first character of a line.
Enter the directive immediately after this initial character, along with the appropriate parameters
values.
Directives supported by the assembler vary according to manufacturer. Table 5-2 summarizes the
CASM05W assembler directives. A caret (^) indicates that a parameter value must follow the
directive. Note also that a space must separate a directive and its parameter value.
5.6.1 BASE
The BASE assembler directive changes the default base of the current file. The parameter
specified must be in the current base or have a base qualifier (prefix or suffix). The next base
remains in effect until the end of the file, or until you enter another BASE directive.
The original default base is hexadecimal, but you can change the default to binary, octal, or
decimal default bases instead. It is good practice to specify a base explicitly so that you are
always sure that base is currently in effect.
5.6.2 Cycle Adder
The CASM05W assembler contains an internal counter for instruction cycles called the cycle
adder. Two assembler directives, CYCLE_ADDER_ON and CYCLE_ADDER_OFF, control
this counter.
When the assembler encounters the CYCLE_ADDER_ON directive, it clears the cycle adder.
The cycle adder starts a running total of instruction cycles as subsequent instructions are
assembled. For instructions that have variables numbers of instruction cycles, the cycle adder
uses the smallest number.
When the assembler encounters the CYCLE_ADDER_OFF directive, it writes the current cycle-
adder value to the .LST file and disables the cycle adder.

5.6.3 Conditional Assembly
The CASM05W assembler allows you to specify blocks of code to be assembled only upon
certain conditions. To set up such conditional assembly procedures, use the conditional
assembler directives summarized in Table 5.2.
Example of Conditional Assembly Directives
$SET debug ;sets debug = true
$SETNOT test ;sets test = false
nop ;always assembles
nop ;always assembles
$IF debug ;if debug = true
jmp start ;assembles
$ELSEIF ;if debug = false
jmp end ;does not assemble
$ENDIF ;
nop ;always assembles
nop ;always assembles
$IF test ;if test = true
jmp test ;does not assemble
$ENDIF ;
5.6.4 INCLUDE
If the CASM05W assembler encounters the INCLUDE directive, it takes source code from the
specified file and continues until it encounters another INCLUDE directive or until it reaches the
end of the main file. When the assembler reaches the end of the main file, it continues taking
source code from the file that contained the include directive.
The file specification of the INCLUDE directive must be in either single or double quotes. If the
file is not in the current directory, the specification should also include the full path name as well
as the filename.
You may nest included to a maximum depth of 10, that is, each included file may contain up to 10
additional included files.
Examples
$INCLUDE “INIT.ASM”
$INCLUDE “C:\project\init.asm*"

ASSEMBLER INTERFACE
M68ICS05POM/D 5-11
5.6.5 MACRO
A macro is a named block of text to be assembled. Similar in some ways to an included file, the
macro allows labels and parameter values.
The MACRO directive begins the macro definition. The name of the macro is the parameter
value for the MACRO direction. All subsequent code, until the assembler encounters the
MACROEND directive, is considered the macro definition.
No assembler directives may be used within a macro, no does the definition require parameter
names. Instead, the macro definition includes the sequential indicators %n for the nth parameter
values of the macro call. The assembler will ignore parameter values on the MACRO directive
line, so such values may be helpful for internal documentation.
Example
This macro example illustrates a macro that divides the accumulator value by 4:
$MACRO divide_by_4 ;starts macro definition
asr a ;divides accumulator by 2
asr a ;divides quotient by 2
$MACROEND ;ends macro definition
This macro example illustrates a macro that creates a time delay:
$MACRO delay count
ldaa #$01
loop: deca
bne loop
$MACROEND
In this macro, the CASM05W assembler ignores the parameter count on the MACRO directive
line. The parameter count merely indicates the role of the parameter value passed to the macro.
That value is substituted for the sequential indicator %1. The first time this macro is called, the
CASM05W assembler changes the label loop, on lines 3 and 4, to loop:0001. If the calling line
delay 100t
invokes this macro, the loop would occur 100 times. The suffix t represents the decimal base.
The CASM05W assembler ignores extra parameter values sent to a macro. If the macro does not
receive enough parameter values, the assembler issues an error message.
Labels change automatically each time they are used. Labels used within macros may not be
longer than 10 characters, because the assembler appends a four-digit hex adecimal number to the
label to insure label uniqueness.

Although code may not jump into a macro, it may jump out of a macro. Macros cannot be
forward-referenced.
5.7 LISTING DIRECTIVES
List directives are source-code keywords that control output to the LST listing file. These
directives pertain only to viewing the source-code output; the directives, which may be
interspersed anywhere in source code, do not affect the actual code assembled. Table 5-4
summarizes the listing directives.
Table 5-3. Listing Directives
Directive Action
eject or page Begins a new page
header ^ Specifies a header on listing pag es; the header can be defined only once; the
default header is blank; the header string is ent er ed in quotes.
list Turns on the . lst file output .
nolist Turns off t he .lst f ile out put. This dir ective is the counterpart of the list
directive; at t he end of a file, this directive keeps the symbol-t able from being
listed.
pagelength ^ Sets the length of the page; the def ault parameter value is 166 lines (! =
decimal)
pagewidth ^ Sets the width of the output, word wrapping additional t ext; the default
parameter value is 160 columns ( ! = decim al) f.
subheader ‘^’ Makes the string specified in q uot es ( double or single) a subheader on t he
listing pag es; the subheader takes ef fect on t he next page.
Note: the car et (^) character following a directive indicates a mandat or y parameter value that
must be supplied.
5.7.1 Listing Files
If a listing file is requested using the L parameter in the command line of the Windows Program
Item Properties, or the Output Listing File option is checked in the Assembler/Compiler tab in
the Environment Settings dialog, the listing file (.LST) is created during the assembly.
This listing file has the same name as the file being assembled, but with the extension .LST. Any
existing file with the same name will be overwritten.

The assembler generates t his field.
Note that this value appears only if the cycle counter (Cycle Cntr) was turned on
befor e assem bly.
Also note that the CC value, which always appears in brackets, is a decimal
value. If a command has several possible cycle counts and the assembler cannot
determine t he act ual num ber , the CC f ield shows the best case ( lowest number ) .
An example of a comm and that may have several possible counts is a branch
command.
VVVVVVVV The thir d field contains a label consisting of four hexadecimal dig it s indicating the
values placed into that mem or y address ( and, possibly, t he next several mem ory
addresses). You m ay refer to this label in other comm ands. The size of this field
depends on the actual opcode. The assembler der ives this field from the source
code.
LLLL The fourth field may contain up to four digit s indicat ing the line count. The
assembler derives this field fr om the source code.
Source

5.7.2 Labels
As you write the program code, you will not necessarily know the addresses where commands
will be located. The assembler solves this problem using a system of labels, providing you with a
convenient way to identify specific points in the program without knowing the exact addresses.
The assembler later converts these mnemonic labels into specific memory addresses and even
calculates the offsets for branch commands in order for the CPU to use them.
Labels within macros must not exceed 10 characters in length.
Examples:
Label:
ThisIsALabel:
Loop_1
This_label_is_much_too_long:
The assembler would truncate the last example to 16 characters.

5.8 PSEUDO OPERATIONS
The CASM05W assembler also allows pseudo operations (in place of opcode mnemonics). The
operations that the assembler allows are summarized in Table 5-5.
Table 5-5. Pseudo Operations Allowed by the CASM05W
Pseudo Op Code Act i on
equ Associates a binary value with a label.
fcb m
or
db m
Defines byte stor age, where m = label, num ber , or string . St rings
generat e ASCI I code for m ultiple bytes; number and label par am eters

Separate mult iple par ameters with commas.
fdb n
or
dw n
Defines word storage, where n = label, number , or string. Two bytes
are gener at ed for each num ber or label.
Separate mult iple par ameters with commas.
org n Sets the or igin to t he value of the number or label n. No forward
ref er ences of n are allowed.
rmb n or ds n Defines stor age, reser ving n bytes, where n = number or label; no
for ward references of n are allowed.
5.8.1 Equate (EQU)
The equate directive associates a binary value with a label. The value may be either an 8-bit
value or a 16-bit address value. This directive does not generate any object code.
During the assembly process, the assembler must keep a cross-reference list where it stores the
binary equivalent of each label. When a label appears in the source program, the assembler looks
in this cross-reference table to find the binary equivalent. Each EQU directive generates an entry
in this cross-reference table.
An assembler reads the source program twice. On the first pass, the assembler just counts bytes
of object code and internally builds the cross-reference table. On the second pass, the assembler
generates the listing file and/or the S-record object file, as specified in the command line
parameters for the assembler. This two-pass arrangement allows the programmer to reference
labels that are defined later in the program.

ASSEMBLER INTERFACE
M68ICS05POM/D5-16
EQU directives should appear near the beginning of a program, before their labels are used by
other program statements. If the assembler encounters a label before it has been defined, the
assembler has no choice but to assume the worse case, and assign the label a 16-bit address
value. This would cause the extended addressing mode to be used in places where the more
efficient direct addressing mode could have been used. In other cases, the indexed 16-bit offset
addressing mode may be used where a more efficient 8-bit or no offset indexed command could
have been used.
5.8.2 Form Constant Byte (FCB)
The arguments for this assembl er directive are labels or numbers (separat ed by commas) that t he
assembler can convert into a single byte of data. Each byte specified by the FCB directive
generates a byte of machine code in the object code file. Use FCB directives to define constants
in a program.
5.8.3 Form Double Byte (FDB)
The arguments for this assembl er directive are labels or numbers (separat ed by comm as) that the
assembler can convert into 16-bit data values. Each argument specified in an FDB directive
generates two bytes of machine code in the object code file.
5.8.4 Originate (ORG)
The originate directive sets the location counter for the assembler. The location counter keeps
track of the address where the next byte of machine code will be stored in memory.
As the assembler translates program statements into machine code commands and data, it
advances the location counter to point to the next available memory location.
Every program has at least one ORG directive, to establish the program’s starting place. Most
complete programs will also have a second ORG directive near the end of the program to set the
location counter to the address where the reset and interrupt vectors are located. You must always
specify the reset vector. It is good practice to also specify interrupt vectors, even if you do not
expect to use interrupts.
5.8.5 Reserve Memory Byte (RMB)
Use this assembler directive to set aside space in RAM for program variables. The RMB
directive does not generate any object code, but it normally generates an entry in the assembler’s
internal cross-reference table.

5.10 USING FILES FROM OTHER ASSEMBLERS
To prepare a source file made by another assembler with the CASM05W, follow these steps:
1. Divide large files into smaller files no larger than 75K. Typically, use one file for
system variables and EQUates, another file for I/O routines. The main file should be
the one called. Remember that include filenames must be in quotes and must contain
the file extensions.
2. Make sure all comments in the source file are preceded by a semicolon.
3. Use the global find-and-replace operation in the editor to change any assembler
directives, listing directives, and/or pseudo operations, if they exist in the source code.
Remember that assembler directives must begin with the character $, /,., or #, and
must start in column 1.
4. If necessary, use the BASE directive to change the default base for operands
(CASM05W defaults to hexadecimal).

CHAPTER 6
ICS05PW SIMULATOR USER INTERFACE
6.1 OVERVIEW
This chapter describes the in-circuit simulator user interface, toolbar buttons, windows, sub-
windows, messages, and menu options.
6.2 THE ICS05PW IN-CIRCUIT SIMULATOR
The ICS05PW.EXE is an in-circuit simulator for Motorola 68HC05P6 and P9 microcontrollers
that runs in Windows 3.x and Windows 95. The ICS05PW can get inputs and outputs (I/O) for
the target device from an external pod, the M68ICS05P board, that is attached to the host
computer. If you want to use actual inputs and outputs (I/O) from your own target board, you
may attach the M68ICS05P board to your target board using the supplied extension cable.
The ICS05PW in-circuit simulator software is the debugging component of a complete
development environment when used in conjunction with the WinIDE editing environment and
the CASM05W command-line assembler.
6.2.1 ICS05PW Simulation Speed
The ICS05PW is not a real-time debugger. The speed at which the simulator executes code is
much slower than the speed at which the actual processor can execute code. Therefore, if there
are any critical timing issues to be resolved, you should use an emulator for the HC05P devices
instead of the ICS05PW.
Alternately, you may simulate using the slow mode, then program an EPROM device to check
the full speed operation.
NOTE
An actual speed of 10KHz indicates that the simulator on your host
PC is running at the same speed as the real MCU with a 20-KHz
crystal (a divide-by-2 is attached to the internal oscillator output).
Typical values for actual speed are 3 to 50 KHz.

SIMULATOR USER INTERFACE
M68ICS05POM/D6-2
To calculate actual speed of the assembled code on the target MCU, you need a stopwatch and
some source code. Follow these steps:
1. Load your code using the LOAD command on the ICS05PW Status Window
command line.
1. Set the program counter to the beginning of the routine for which you wish to
measure the speed.
2. Clear the cycle counter using the CYCLE (or CY) command with the 0 parameter,
then press Enter:
3. Ready your stopwatch.
4. Enter the GO or G command on the ICS05PW Status Window command line.
5. Start the stopwatch and press the ENTER button simultaneously to begin code
execution.
6. After 10 seconds, simultaneously stop the watch and execution (the fastest way to
stop execution is to press the spacebar). Execution halts.
7. Now enter the CYCLES or CY command on the Status Window command line; the
decimal value cycle count is displayed.
8. Divide the cycle count by 10. The result is the actual speed in KHz.
6.2.2 System Requirements for Running the ICS05PW
The ICS05PW runs under W indows 3.1 or Windows 95. There is a separate 32-bit version of the
ICS05PW software for Windows 95/NT available directly from P&E Microcomputer Systems.
Your host computer should have a minimum of 2 MB of RAM (system memory) available for
assembly processes, as well as sufficient disk space to store the files that the ICS05PW creates.
6.2.3 File Types and Formats
You can use a number of file types in conjunction with the ICS05PW simulator. The following
topics describe the use and structure of each type.
• Project Files: Project files store two types of information:
− Desktop information includes all the information stored concerning the files
that are currently open in the project. Whenever you save the project file,
WinIDE records information about each window open in the desktop,
including:
• Window size
• Window position

• Window style (Maximized/Minimized/Normal)
• Markers currently set
− Environment Settings
• User settings
• WinIDE configuration parameters as specified in the Environment
Settings dialog tabs
When you open the project, or if the project is open when the W inIDE starts, files are
all opened with the settings stored in the project file.
• S19 (Object) Files: The ICS05PW software accepts any standard Motorola S19 files
as input for simulation. S19 object files can be created by any HC05 assembler (such
as CASM05W), and contain the actual object code that is simulated by the ICS05PW.
Specify the S19 files to use on the command line or load it using the LOAD command
in the ICS05PW Status window.
− The object file has the same name as the file assembled, with the extension
.HEX or .S19, and contains the actual assembled (or object) code to debug. If
you specify an object file in the environment settings, it is created during
assembly.
− The CASMW (and some other assemblers) product object files in the .S19
format. The Motorola S19 object code format is described in detail in
Appendix A. HEX files are the Intel 8-bit object code format.
• Map Files contain source level debugging information. To debug symbolic or source
code in the code window you must also load one or more P&E map-files. The *.MAP
source-level map file can be generated by specifying the map files option on the
command line when running the CASMW assembler, or loaded using the LOADMAP
command in the ICS05PW Status window. If you specify a map file in the
environment settings, it is created during assembly.
NOTE
Map files contain directory information, so cannot be moved. To
place map files in another directory, move the map file to the new
directory and reassemble the file in the new directory so the new
map file will contain the correct directory information.
If you use a third party assembly language or C compiler, it must
be able to produce compatible source-level map files.
• Error Files contain assembly error information. The CASMW highlights any errors
that it encounters during the assembly, and displays the error message in the CASMW
window. Depending on the environment settings, the assembler may also open the file
in which the error was encountered, and create an error file with the assembly
filename and the .ERR extension.

M68ICS05POM/D6-4
• Script Files are plain ASCII text files containing ICS05PW simulator commands.
You may use any command in the ICS05P command set in script files. Running the
script file then has the effect of entering the commands in it in the ICS05PW
command line. You can create script files in the WinIDE editor, or you can use files
created by other text editors following these rules:
− Enter each command on its own line.
− Preface comments with a semi-colon.
− Use commands from the ICS05PW command set and WAIT.
• Listing Files display each line of source code and the resulting (assembled or
compiled) object code. Listing files show exactly how and where each code was
assembled.
− If you specify a listing file in the environment settings, it is created during
assembly. The listing file will have the same name as the file being assembled,
with the .LST extension, and will overwrite any previous file with the same
name.
− Listing files contains these fields in the following format:
AAAA [CC] VVVVVVVV LLLL Source Code . . . .
Where:
AAAA First four hexadecimal digits are the address of the
command in the target processor memory.
[CC] The number of machine cycles used by the opcode. This
value, which always appears in brackets, is a decimal value.
If an instruction has several possible cycle counts (as would
be the case when the assembler encounters a branch
instruction) and the assembler cannot determine the actual
number of cycle counts, the CC field will show the best
case (lowest number).
VVVVVVVV Hexadecimal digits (the number of which depends on the
actual opcode) representing values put into that memory
address.
LLLL Line count.
Source code The actual source code
At the end of the listing file is the symbol table listing every label and its
value.

• Log Files are simple ASCII text files, sometimes called scratch pad files. The log file
records the sequence and content of commands ex ecuted, and the debugger responses
to the commands. You can view log files from within the WinIDE editor. The
ICS05PW simulator creates log files if the LOGFILE or LF command is active.
6.3 START ING ICS05PW
You can start the ICS05PW simulator by itself in standalone mode (with no inputs or outputs
from the target), or run it from within the WinIDE editor. You can also modify the ICS05PW
environment in WinIDE editor.
• To run the simulator in standalone mode, double click the ICS05PW icon using either
of these methods:
− In Windows 3.x, in the Program Manager, double click the ICS05PW icon in
the ICS05PW Program Group.
− In Windows 95, choose the ICS05PW icon from the ICS05PW group in the
Start menu.
• To run the simulator from the WinIDE editor, use either of these methods:
− Click the Debugger (EXE1) button on the WinIDE toolbar
− Press the F6 Hotkey
• To modify how the software starts from WinIDE editor:
1. From the WinIDE Environment menu, choose the Setup Environment option
to open the Environment Settings dialog.
2. Select the EXE1 Debugger tab heading (see Figure 4-17), if it is not in already
on top, to set options for the ICS05PW simulator. For more information about
the options in the tab, see paragraph 4.10.5.4.
After startup, the software will establish communication with the board at the given parameters
and the status bar will read Attempting to contact COM 1.
• If the ICS05PW software can communicate with the pod through the serial port, the
status bar message reads, Contact with pod established.

• If the software is not able to connect with the board, the Can’t Contact Board dialog
(Figure 6-1) appears.
Figure 6-1. Can’t Contact Board Dialog
If the communication parameters for the communications port and baud rate are incorrect in the
Can’t Contact Board dialog, change them and then press the RETRY button. If the board is not
connected or you do not wish to use I/O from the board, then click the SIMULATION only
button. Otherwise, press the EXIT Application button.
When you start the ICS05PW software for the first time, the Pick Device dialog will offer you the
choice of the P6 or P9 Device (chip). If you want to open this dialog and change the device later,
enter the CHIPMODE command in the ICS05PW Status Window command line.

6.11 CYCLES WINDOW
Use the Cycles Window (Figure 6-16) to view the number of processor cycles that passed during
execution of code in the simulator. This is valuable if you want to count the number of cycles
that a section of code requires. In order to calculate the timing of code for a device, take the
number of cycles shown in the window and multiply by the amount of time that a cycle
represents in the target system. (i.e. for a 2MHz HC05, the time per cycle is 500 ns (½ µsec.)
Figure 6-16. Cycles Window
6.12 STACK WINDOW
Use the Stack window (Figure 6-17) to view:
• Values that have been pushed on the stack
• The stack pointer value
• CPU results if a RTI or RTS instruction is executed at that time.
To display the stack window, enter the STACK command in the ICS05PW Status Window
command line.

• Data values in the stack
• Values of the condition code register (CCR), accumulator (A) and index register (X).
This information indicates the restored state of the stack upon the return from the interrupt.
6.12.2 Subroutine Stack
During execution of a subroutine, the stack window displays the subroutine stack that indicates
the restored state of the CPU upon return from a subroutine.
NOTE
M68HC05 MCUs store information in the stack (1) during an
interrupt or (2) during execution of a subroutine. The stack window
shows both these possible interpretations of stack data. It is
important to know whether program execution is in an interrupt or
in a subroutine, to know which stack data interpretation is valid.
6.13 TRACE WINDOW
Use the Trace Window (Figure 6-18) to view instructions captured while tracing is enabled.
Figure 6-18. Trace Window
To display the Trace Window, enter the SHOWTRACE command in the command line of the
ICS05PW Status Window.
To enable or disable tracing, enter the TRACE command. If tracing is off, the command will
toggle tracing on; if tracing is on, the command toggles tracing off.
The trace buffer is a 1024 instruction circular buffer that contains all addresses that have been
executed. When the trace window displays instructions, it disassembles instructions at the
addresses stored in the trace buffer. For this reason, the tracing function cannot be used for self-
modifying code. If a buffer slot does not have an address stored in it, the trace window displays

7.2 ICS05PW COMMAND SYNTAX
A command is a line of ASCII text that you enter from the computer keyboard. For ICS05PW
debugging commands, enter the command and its arguments in the ICS05PW Status window
command line. Press Enter to terminate each line and activate the command. The typical
command syntax is:
command
[<argument>]...
Where:
command A command name, in upper- or lower-case letters.
<argument> An argument indicator; when arguments are italicized, they
represent a placeholder for the actual value you enter; when not
italicized, they indicate the actual value to enter. Table 7-1 explains
the possible argument values.
In command syntax descriptions:
[ ] brackets enclose optional items,
| a vertical line means or,
... an ellipsis means that you can repeat the preceding item,
( ) parentheses enclose items only for syntactical purposes
Except where otherwise noted, numerical values in debugging command examples are
hexadecimal.

BR Set Instruction Breakpoint
The BR command displays or sets instruction breakpoints, according to its parameter values:
• If you enter no parameter values, the BR command displays a list of all current
breakpoints in the status window.
• If you enter an <address> value, the BR command sets a breakpoint at the specified
address.
You may also enter an optional value <n> with the address to specify a break count. The BR
command sets a breakpoint at the specified address, but code execution does not break until the
nth time it arrives at the breakpoint.
NOTE
The maximum number of breakpoint addresses is 64. Each BR,
BREAKA, BREAKSP, or BREAKX command that includes an
address value uses an additional breakpoint address, unless the
address is a duplicate. For example, if 64 BR commands already
have taken up 64 addresses, the only way to include an address
value in a BREAKA, BREAKSP, or BREAKX command is to
duplicate one of those 64 addresses.
If source code is displayed in either code window, you can set, remove, or clear all breakpoints
using mouse or keyboard commands:
1. Position the cursor on the line of code for which you want to set a breakpoint.
2. Press the right mouse button once to open the Code Window Shortcut Menu.
3. Select Toggle Breakpoint at Cursor option. If there is no current breakpoint set at this
line of code, a breakpoint will be set. If there is a current breakpoint set at this line of
code, the breakpoint will be removed.
To remove all breakpoints:
• Enter the NOBR command in the Status Window command line.

BREAKA Set Accumulator Breakpoint
The BREAKA command sets an accumulator breakpoint to halt code execution when the value
of the accumulator equals the specified n value.
• With an n value, the command forces a break in execution as soon as the accumulator
value equals n.
• With n and address values, the command forces a break in execution when the
accumulator value equals n and execution arrives at the specified address. (If the
accumulator value changes from n by the time execution arrives at the address, no
break occurs).
NOTE
The maximum number of breakpoint addresses is 64. Each BR,
BREAKA, BREAKSP, or BREAKX command that includes an
address value uses an additional breakpoint address, unless the
address is a duplicate. For example, if 64 BR commands already
have taken up 64 addresses, the only way to include an address
value in a BREAKA, BREAKSP, or BREAKX command is to
duplicate one of those 64 addresses.
If you enter the BREAKA command without an address value, the halt in code execution clears
the accumulator breakpoint. To cancel the accumulator breakpoint before the halt occurs, enter
the BREAKA command without any parameter values. (If you enter the BREAKA command
without an address value, the accumulator breakpoint does not show in the BREAKPOINT
WINDOW.)
If you enter the BREAKA command with an address value, you may clear the accumulator
breakpoint by one of these methods:
• Enter the NOBR command
• Position the cursor on that address in the code window, then press the right mouse
button, and select Toggle Breakpoint at Cursor menu item.
Syntax:
BREAKA
[<n> [<address>]]
where:

BREAKSP Set Stack Pointer Breakpoint
The BREAKSP command sets a stack pointer breakpoint to halt code execution when the value
of the stack pointer equals a specified value.
• With an n value, the command forces a break in execution as soon as the stack pointer
value equals n.
• With n and address values, th e BREAKSP command forces a halt in ex ecution when
the stack pointer value equals n and execution arrives at the specified address. (If the
stack pointer value changes from n by the time execution arrives at the address, no
break occurs).
NOTE
The maximum number of breakpoint addresses is 64. Each BR,
BREAKA, BREAKSP, or BREAKX command that includes an

the stack pointer breakpoint. To cancel the stack pointer breakpoint before the halt occurs, enter
the BREAKSP command without any parameter values. (If you enter the BREAKSP command
without an address value, the stack pointer breakpoint does not show in the Breakpoint
Window.)
If you enter the BREAKSP command with an address value, you may clear the stack pointer

BREAKX Set Index Register Breakpoint
The BREAKX command sets an index breakpoint to halt code execution when the value of the
index register equals the specified n value.
• With an n value, the command forces a break in execution as soon as the index
register value equals n.
• With n and address values, the command forces a halt in execution when the index
register value equals n and execution arrives at the specified address. (If the index
register value changes from n by the time execution arrives at the address, no halt
occurs).
NOTE
The maximum number of breakpoint addresses is 64. Each BR,
BREAKA, BREAKSP, or BREAKX command that includes an
address value uses an additional breakpoint address, unless the
address is a duplicate. For example, if 64 BR commands already
have taken up 64 addresses, the only way to include an address
value in a BREAKA, BREAKSP or BREAKX command is to
duplicate one of those 64 addresses.
If you enter the BREAKX command without an address value, the halt in code execution clears
the index register breakpoint. To cancel the index register breakpoint before the halt occurs, enter
the BREAKX command without any parameter values. (If you enter the BREAKX command
without an address value, the index register breakpoint does not show in the Breakpoint
Window.)
If you enter the BREAKX command with an address value, you may clear the index register
breakpoint using one of these methods:
• Enter the NOBR command
• Position the cursor on that address in the code window, then press the right mouse
button, and select Toggle Breakpoint at Cursor menu item.
Syntax:
BREAKX
[<n> [<address>]]
where:
<n> Index register value that triggers a break in execution.
<address> Optional address for the break in execution (when that the index
register value equals n).

C Set/Clear Carry Bit
The C command sets or clears the C bit of the condition code register (CCR).
NOTE
The CCR bit designators are in the lower portion of the CPU
window. The CCR pattern is 111HINZC (H is half-carry, I is IRQ
interrupt mask, N is negative, Z is zero and C is carry). A letter in
these designators means that the corresponding bit of the CCR is
set; a period means that the corresponding bit is clear.
Syntax:

CAPTURE Capture Changed Data
The CAPTURE command specifies locations to be monitored for changes in value. If the value
of such a location changes and if a capture fil e is open, the file records t he change in val ue. (See
the CAPTUREFILE or CF command for more information about capture files).
To stop monitoring a location, specify that same location in another CAPTURE command, or
close the capture file. (Closing the capture file undoes the specifications for all monitoring
locations).
NOTE
Before you enter the CAPTURE command, open a capture file via
the CAPTUREFILE or CF command. The CAPTURE command
has no effect unless a capture file is open.
Syntax:
CAPTURE
<address> [<address>...]
where:
<address> Location to be monitored for a change in value.
Examples:
CAPTURE PORTA Monitor location PORTA for any value changes.
CAPTURE C0 Monitor RAM location C0 for any value changes.
CAPTURE D0 D1 D2 Monitor for any value changes in an array of locations.

CAPTUREFILE or CF Open/Close Capture File
The CAPTUREFILE command opens a capture fi le to record changed values. If the specified file
does not yet exist, this command creates the file. If the file already exists, you can use an optional
parameter to specify whether to overwrite existing contents (R, the default) or to append the log
entries (A). If you omit this parameter, a prompt asks for this overwrite/append choice.
The command interpreter does not assume a filename extension for the capture file. To close the
capture file, enter this command without any parameter values.
The CF and CAPTUREFILE commands are identical. If no CAPTURE command has specified
locations to be monitored, the CF and CAPTUREFILE commands have no effect.
NOTES
The CAPTURE command specifies the location to be monitored
for value changes. Closing the capture file deletes the location
specification. The simulator continues writing to an open capture
file. The capture file must be closed within a reasonable time, to
prevent the file from growing large.
Syntax:
CAPTUREFILE
[<filename> [R | A]]
where:
<filename> Name of the capture file.
Examples:
CAPTUREFILE TEST.CAP Open capture file TEST.CAP
CF TEST4.CAP A Open capture file TEST4.CAP; append new entries

The CCR command sets the condition code register (CCR in the CPU) to the specified
hexadecimal value. The value entered with the command displays in the CPU Window.
NOTE
The CCR bit designators are in the lower portion of the CPU
window. The CCR binary pattern is 111HINZC (H is half-carry, I
is IRQ interrupt mask, N is negative, Z is zero and C is carry). A
letter in these designators means that the corresponding bit is set; a
period means that the corresponding bit is clear.
Syntax:
CCR
<n>
where:
<n> The new hexadecimal value for the CCR.
Example:
CCR E4 Assign the value E4 to the CCR. This makes the binary
pattern 11100100; the N bit set, other bits clear.

DEBUGGING COMMAND SET
M68ICS05POM/D 7-55
MACRO Execute Batch File
The MACRO command executes a macro file, a file that contains a sequence of debug
commands. Executing the macro file has the same effect as executing the individual commands,
one after another. The SCRIPT command is identical.
Entering this command without a filename value brings up a list of macro (.MAC) files in the
current directory. You can select a file for execution directly from this list.
NOTE
A macro file can contain the MACRO command, allowing you to
next macro files up to 16 levels deep.
The most common use of the REM and WAIT commands is within
macro files. The REM command displays comments while the
macro file executes; the WAIT command establishes a pause
between the execution of the macro file commands.
If a startup macro file is in the directory, startup routines run the macro file each time the
application starts. See the STARTUP command for more information.
Syntax:
MACRO
<filename>
where:
<filename> The name of a macro file to be executed, with or without ex tension
.MAC. The filename can be a pathname that includes an asterisk
(*) wildcard character. If so, the software displays a list of macro
files, for selection.
Examples:
MACRO INIT.MAC Execute commands in file INIT.MAC.
SCRIPT * Display names of all .MAC files (then execute the selected
file).
MACRO A:* Display names of all .MAC files in drive A (then execute
the selected file).
MACRO Display names of all .MAC files in the current directory,
then execute the selected file.

MM Modify Memory
The MM command directly modifies the contents of m emory beginning at the specified address.
The optional variant specifies whether to fill the block in bytes (.B, the default), in words (.W),
or in longs (.L). If, however, the command has only an address value, the Modify Memory dialog
(Figure 7-3) appears showing the specified address and its present value. Use the dialog to enter a
new value for the address or to modify the address type by selecting 8-bit bytes, 16-bit words, 32-
bit longs. To modify several memory locations from this dialog, enter the new value in the New
Value text box and press the >> button to increment the current address, or the << button to
decrement the current address, or the = button to display the same address.
Figure 7-3. Modify Memory Dialog
If the MM command includes optional data values, the software assigns the values to the
specified addresses sequentially, then the command ends. No window appears in this case.
Syntax:
MM
[.B|.W|.L] <address>[<n> ...]
where:
<address> The address of the first memory location to be modified.
<n> The value(s) to be stored (optional).
Examples:

WAIT Wait for
n
Cycles
The WAIT command delays simulator command execution by the specified number of cycles.
This command is used in MACRO files to control when inputs come into the simulator. If a
WAIT command is encountered, control is passed back to the keyboard. Then the macro file
execution waits for a command to be entered such as GO or STEP, which starts MC U execution
once again. As soon as the number of cycles that pass is equal to the <n> value of the WAIT
command, the simulator resumes executing commands of the macro file until another WAIT is
encountered or the two mentioned conditions happens again.
Syntax:
WAIT
<n>
where:
<n> The hexadecimal number of cycles to wait.
Example:
WAIT A Delay command execution for 10 MCU cycles.

EXAMPLE PROJECT
M68ICS05POM/D 8-3
The example project consists of 12 source code files created in the WinIDE editor. The files are
then assembled into *.ASM files using WinIDE Assemble/Compile toolbar button. The 12 files
are then listed in a separate file MAIN.ASM.
The MAIN.ASM file consists of $INCLUDE functions, each followed by the filename for the
source code file, followed by an optional comment describing the function of the code in that
file. Using the $INCLUDE function in a main file lets you organize your source code logically
into a number of small files, ultimately making it easier to develop, manage, and work with the
source code. For more information about using the $INCLUDE function, see paragraph 5.6.4.
The example MAIN.ASM file:
***********************************************************
Include files
***********************************************************
$include "equates.asm"
$include "init.asm"
$include "charge.asm"
$include "dcharge.asm"
$include "options.asm"
$include "misc.asm"
$include "readv.asm"
$include "isr.asm"
$include "display.asm"
$include "eeprom.asm"
$include "text.asm"
$include "vectors.asm"
8.2.3 Assemble the Project
Now you are ready to assemble your project. In the WinIDE, follow these steps:
1. With the MAIN.ASM file in the active window, press the Assemble/Compile File
button (third button from the left) on the WinIDE toolbar to start the assembler from
the WinIDE editor.
2. The assembler concatenates the files in the source code window, assembles them, and
creates the output MAIN.ASM file. MAIN.ASM replaces any previous assembly code
file of the same name in the same directory.
3. If the assembler encounters errors during assembly, the assembler stops and the first
error is displayed highlighted in red in the source file. To correct the errors, click on
the Debugger (EXE1) toolbar button (left-most button) on the WinIDE toolbar to
open or move to the ICS05PW simulator to debug the source code. When you have
finished debugging the code in the ICS06PW simulator, return to the WinIDE editor
by clicking the Back to Editor button (the left-most button) in the ICS05PW toolbar.
4. Continue assembling, debugging, and editing the source files until the assembly
completes successfully.

S-RECORD INFORMATION
M68ICS05POM/D A-1
APPENDIX A
S-RECORD INFORMATION
A.1 OVERVIEW
The Motorola S-record format was devised for the purpose of encoding programs or data files in
a printable format for transport between computer platforms. The format also provides for editing
of the S-records and monitoring the cross-platform transfer process.
A.2 S-RECORD CONTENT
Each S-record is a character string composed of several fields which identify:
• record type
• record length
• memory address
• code/data
• checksum
Each byte of binary data is encoded in the s-record as a two-character hexadecimal number:
• The first character represents the high-order four bits of the byte
• The second character represents the low-order four bits of the byte
The five fields that comprise an S-record are shown in the Table A-1.

compatibilit y with teletypewriter, some programs m ay
limit the num ber of bytes to as few as 28 (56 printable
characters in the S-record)
Checksum 2 Least significant byte of the one’s complement of t he
sum of t he values repr esent ed by the pair s of
characters m aking up t he r ecor d length, addr ess, and
the code/data fields
Each record may be terminated with a CR/LF/NULL. Additionally, an S-record may have an
initial field to accommodate other data such as line number generated by some time-sharing
systems.
Accuracy of transmission is ensured by the record length (byte count) and checksum fields.
A.3 S-RECORD TYPES
Eight types of S-records have been defined to accommodate the several needs of the encoding,
transport, and decoding functions. The various Motorola upload, download, and other record
transport control programs, as well as cross assemblers, linkers, and other file-creating or
debugging programs, utilize only those S-records which serve the purpose of the program. For
specific information on which S-records are supported by a particular program, consult the user
manual for the program.
NOTE
The ICS05PW supports only the S0, S1, and S9 record types. All
data before the S1 record is ignored. Thereafter, all records must be
S1 type until the S9 record, which terminates data transfer.

There is no code/ dat a field.
Only one termination record is used for each block of S-records. Normally, only one header
record is used, although it is possible for multiple header records to occur.
A.4 S-RECORD CREATION
S-record format programs may be produced by dump utilities, debuggers, cross assemblers, or
cross linkers. Several programs are available for downloading a file in the S-record format from a
host system to an 8- or 16-bit microprocessor-based system.

APPENDIX B
SUPPORT INFORMATION
B.1 OVERVIEW
This appendix provides technical support information for the M68ICS05P In-Circuit Simulator
Kit, including:
• Functional description of the kit
− Emulation
− Programming
• Troubleshooting the Quick Start
• Troubleshooting the Programmer
• Parts List
B.2 FUNCTIONAL DESCRIPTION OF THE KIT
The M68ICS05P pod consists of two components:
• P emulator
• 705P Programmer (including VPP generation)
B.2.1 The Emulator
The core of the emulation component of the pod U4 is the MC68HC705C8 device. This MCU
provides the required input/output information that lets the host computer simulate code,
performing all functions except for maintaining port values. The internal EPROM in the C8
device runs a program which generates the appropriate port values.
The ICS05PW software on the host computer lets the host computer become a simulator. When
the ICS requires port data, the computer requests the data through the host’s serial connection to
the C8 device. The C8 responds by sending the data to the host via the serial connection. It is this
arrangement that lets the ICS simulator interface with the real world.
Freescale Semiconductor, I
Freescale Semiconductor, Inc.
For More Information On This Product,
Go to: www.freescale.com
nc...
SUPPORT INFORMATION
M68ICS05POM/DB-2
The M68ICS05P pod’s 7.37-MHz crystal provides a clock signal for the C8 device. The clock
runs the device at a 3.68-MHz bus rate. Note that the simulation speed will be less than the bus
rate, because the host computer is the simulator.
NOTE
The C8 device differs from the P device in that it does not have
programmable pull-ups. Accordingly, the M68ICS05P pod has
external pull-up resistors, which you can select using jumper
headers J4 through J13. To disable the pull-ups, remove the
fabricated jumpers from the corresponding headers.
B.2.2 Programming
In addition to controlling the input and output port signals, the C8 MCU also controls the
programming of the P devices.
NOTE
To program a 705P device, the EPROM of the device must first be
erased.
Programming begins with the initialization sequence:
• The host computer sends signals to the C8 device to initiate the programming
sequence, then releases the RESET line.
• The host computer then sends data to the 705P device through the C8.
• The 705P device self-programs its EPROM array using the data downloaded by the
host computer.
• The pod’s MC34063 (U3) device generates the programming voltage (16.5 volts),
controlled at the programming socket by the switch S1 (the Programmer software
prompts you to turn switch S1 on or off as appropriate). In the case of the 705P, this
programming voltage is used only to put the P device in the programming mode. The
P device contains an internal charge pump that supplies internal VPP.
B.3 TROUBLESHOOTING THE QUICK START
If you should experience difficulties quick-starting your kit using the procedure outlined in
paragraph 1.7, follow these steps:
1. If the 705C8 part (at board location U4) is a windowed device, make certain that a
black opaque label covers the window.
2. Make sure that no hardware security key or other devices are attached to the serial
port.

SUPPORT INFORMATION
M68ICS05POM/D B-3
3. Make sure that the serial cable is correctly attached to the pod, and to the correct
serial port on the host computer.
4. Check the power supply: first make sure that the pod is not connected to the power
supply, then measure the power to confirm that it produces 5 volts. Make sure the
power connector is securely attached. You can measure this voltage with a voltmeter’s
ground connection to the tab of U1 (7805), and the U1’s output pin (the pin located
the closest to R1). This voltage should measure ±.5V (5%).
5. With the pod still disconnected, measure the voltage at connector U1; if it is less than
5 volts:
a. Verify that your power supply is properly plugged into an active wall socket.
b. Verify that the power supply is not being current limited, but providing 9 volts
to the board. You can measure the voltage at the opposite pin of U1 (located
closest to the edge of the board).
c. Remove the C8 part. If the voltage at U1 climbs to 5 volts, the C8 may be
defective. Remove the U5 part.
d. If the voltage is still below 5 volts with both the U4 and U5 removed, the
board may be defective.
e. Call Motorola Board Repair (800-451-3464) to arrange for replacement.
NOTE
To replace the C8 or P9 part, you must use a programmed
replacement part. It is not sufficient to substitute any C8 part. If a
programmed replacement is not available, you may be able to
program a replacement part yourself by downloading the file
ICS05P.ZIP from Motorola’s freeware bulletin board (512-891-
3733).
6. If you measure 5 volts at U1 when the C8 part is installed, measure the voltage
between VDD (pin 3) and VSS (pin 20) of the C8 part at U4. If the level is not also 5
volts, check for a bent pin or other structural problem with the socket or the board
trace. If you can find no structural probl em, cal l Moto rola Board Repair t o arrange for
a board replacement.
7. If there are 5 volts between pins 3 and 20, use an oscilloscope to check the output of
pin 39 of the device at U4. Set the oscilloscope to 0.5 (sec per division. You should
observe approximately 3.5 cycles per division; this corresponds to a 7.36 MHz signal.
If you do not get this result, it may be due to any of these problems:
a. Bad crystal at location Y1
b. Bad resistor at location R21
c. Bad capacitor at location C19 or C20
Freescale Semiconductor, I

SUPPORT INFORMATION
M68ICS05POM/DB-4
d. Bad C8 part at location U4
e. Bad socket at location U4
f. Broken trace on pod
g. Cold solder joint on pod
8. If, after checking the board parts, you still have not found the problem, measure the
signals on the clock and serial input pins (2, 3) of connector P2. There should be
activity on these pins when you enter the POD command. If there is no activity on
these pins, check for the following faults:
a. Bad C8 part at location U4
b. Bad socket at location U4
c. Bad connector at location J2
d. Broken trace on pod
e. Cold solder joint on pod
9. If the problem persists, check LED at D1: remove the C8 device, then short socket pin
4 to ground. If the LED does not light, it may be defective or installed backwards.
10. If during the quick-start, the LED at D1 still does not flash, consult a field application
engineer from your Motorola distributor or sales office.
11. If during the quick-start, the LED at D1 continues to flash, check that U4 pin 11 goes
high when you push switch S3. If it does not go high, ohm out resistor R13 and switch
S2. Consult Motorola Board Repair if needed.
B.4 TROUBLESHOOTING THE PROGRAMMER
If you should experience difficulties when programming a 705P part with which you can perform
other simulator functions, follow these steps:
1. Test the socket XU1/XU2:
a. Verify that no part is in socket XU1/XU2.
b. Verify that the voltage on pin 28 of the socket is 5 volts. If not, the socket may
be bad or there may be a bad pod trace. If you such either, refer to
Troubleshooting the Quick Start (above).
2. Calibrate VPP: If pin 13 has 5 volts, calibrate the VPP using these steps:
a. Turn switch S2 ON.
b. Measure the signal on pin 2 of socket U2.
c. Adjust potentiometer VR1 until your meter reads 16.5 volts.
d. Turn switch S2 to OFF and disconnect VDD power

3. Retest programmer:
a. In the ICS, enter the PROGRAM command and follow the programming
instructions that appear on the screen.
b. Before reinserting the 705P device in socket XU1/XU2, make sure that its
erase window is covered.
c. Choose the BLANK CHECK programming option. There should be no
activity on pin 16 of socket U2.
Use the oscilloscope to measure VPP as the 705P device is being programmed; the VPP should not
drop below 16 volts. If the VPP drops below 16 volts, either or both the 705P device or the
MC34063 device may be defective.
To replace defective parts, call Motorola Board Repair (800-451-3464).

GLOSSARY
M68ICS05POM/D Glossary-1
GLOSSARY
8-bit MCU A microcontroller whose data is communicated over a data bus
made up of eight separate data conductors. Members of the
M68HC05 family of microcontrollers are 8-bit MCUs.
A Abbreviation for the accumulator of the M68HC05 MCU.
accumulator An 8-bit register of the M68HC05 CPU. The contents of this
register may be used as an operand of an arithmetic or logical
instruction.
assembler Software program that translates source code mnemonics into
opcodes that can then be loaded into the memory of a
microcontroller.
assembly language Instruction mnemonics and assembler directives that are
meaningful to programmers and can be translated into an object
code program that a microcontroller understands. The CPU uses
opcodes and binary numbers to specify the operations that make up
a computer program. Humans use assembly language mnemonics
to represent instructions. Assembler directives provide additional
information such as the starting memory location for a program.
Labels are used to indicate an address or binary value.
ASCII American Standard Code for Information Interchange. A widely
accepted correlation between alphabetic and numeric characters
and specific 7-bit binary numbers.
breakpoint During debugging of a program, it is useful to run instructions until
the CPU gets to a specific place in the program, and then enter a
debugger program. A breakpoint is established at the desired
address by temporarily substituting a software interrupt (SWI)
instruction for the instruction at that address. In response to the
SWI, control is passed to a debugging program.
byte A set of exactly eight binary bits.
CAbbreviation for “carry/borrow” in the condition codes register of
the M68HC05. When adding two unsigned 8-bit numbers, the C bit
is set if the result is greater than 255 ($FF).

GLOSSARY
M68ICS05POM/DGlossary-2
CCR Abbreviation for “condition codes register” in the M68HC05. The
CCR has five bits (H, I, N, Z, and C) that can be used to control
conditional branch instructions. The values of the bits in the CCR
are determined by the results of previous operations. For example,
after a load accumulator (LDA) instruction, Z will be set if the
loaded value was $00.
clock A square wave signal that is used to sequence events in a
computer.
command set The command set of a CPU is the set of all operations that the CPU
knows how to perform. One way to represent an instruction set is
with a set of shorthand mnemonics such as LDA meaning “load
A.” Another representation of an instruction set is the set of
opcodes that are recognized by the CPU.
condition codes register The CCR have five bits (H, I, N, Z, and C) that can be used to
control conditional branch commands. The values of the bits in the
CCR are determined by the results of previous operations. For
example, after a load accumulator (LDA) instruction, Z will be set
if the loaded value was $00.
CPU Central Processor Unit. The part of a computer that controls
execution of instructions.
CPU cycles A CPU clock cycle is one period of the internal bus-rate clock.
Normally this clock is derived by dividing a crystal oscillator
source by two or more so the high and low times will be equal. The
length of time required to execute an instruction is measured in
CPU clock cycles.
CPU registers Memory locations that are wired directly into the CPU logic
instead of being part of the addressable memory map. The CPU
always has direct access to the information in these registers. The
CPU registers in an M68HC05 are A (8-bit accumulator), X (8-bit
index register), CCR (condition codes register containing the H, I,
N, Z, and C bits), SP (stack pointer), and PC (program counter).
cycles See CPU cycles
data bus A set of conductors that are used to convey binary information
from a CPU to a memory location or from a memory location to a
CPU; in the M68HC05, the data bus is 8-bits.

M68ICS05POM/D Glossary-3
development tools Software or hardware devices used to develop computer programs
and application hardware. Examples of software development tools
include text editors, assemblers, debug monitors, and simulators.
Examples of ha5rdware development tools include simulators,
logic analyzers, and PROM programmers. An in-circuit simulator
combines a software simulator with various hardware interfaces.
EPROM Erasable, Programmable Read-Only Memory. A non-volatile type
of memory that can be erased by exposure to an ultra-violet light
source. MCUs that have EPROM are easily recognized by their
packaging: a quartz window allows exposure to UV light. If an
EPROM MCU is packaged in an opaque plastic package, it is
termed a “one-time-programmable” OTP MCU, since there is no
way to erase and rewrite the EPROM.
H Abbreviation for “half-carry” in the condition codes register of the
M68HC05. This bit indicates a carry from the low-order four bits
of an 8-bit value to the high-order four bits. This status indicator is
used during BCD calculations.
I Abbreviation for “interrupt mask bit” in the condition codes
register of the M68HC05.
index register An 8-bit CPU register in the M68HC05 that is used in indexed
addressing mode. The index register (X) can also be used as a
general purpose 8-bit register (in addition to the 8-bit accumulator).
input-output (I/O) Interfaces between a computer system and the external world: for
example, a CPU reads an input to sense the level of an external
signal and writes to an output to change the level on an external
signal.
instructions Instructions are operations that a CPU can perform. Instructions are
expressed by programmers as assembly language mnemonics. A
CPU interprets an opcode and its associated operand(s) as an
instruction.
listing A program listing shows the binary numbers that the CPU needs
alongside the assembly language statements that the programmer
wrote. The listing is generated by an assembler in the process of
translating assembly language source statements into the binary
information that the CPU needs.
MCU Microcontroller: a complete computer system including CPU,
memory, clock oscillator, and I/O on a single integrated circuit.

GLOSSARY
M68ICS05POM/DGlossary-4
memory location In the M68HC05, each memory location holds one byte of data and
has a unique address. To store information into a memory location
the CPU places the address of the location on the address bus, the
data information on the data bus, and asserts the write signal. To
read information from a memory location the CPU places the
address of the location on the address bus and asserts the read
signal. In response to the read signal, the selected memory location
places its data onto the data bus.
NAbbreviation for “negative,” a bit i n the conditi on codes register of
the M68HC05. In twos-complement computer notation, positive
signed numbers have a zero in their MSB and a negative numbers
have a one in their MSB. The N condition code bit reflects the sign
of the result of an operation. After a load accumulator instruction,
the N bit will be set if the MSB of the loaded value was a one.
object code file A text file containing numbers that represent the binary opcodes
and data of a computer program. An object code file can be used to
load binary information into a computer system. Motorola uses the
S-record file format for object code files.
operand An input value to a logical or mathematical operation.
opcode A binary code that instructs the CPU to do a specific operation in a
specific way. The M68HC05 CPU recognizes 210 unique 8-bit
opcodes that represent addressing mode variations of 62 basic
instructions.
OTPROM A non-volatile type of memory that can be programmed but cannot
be erased. An OTPROM is an EPROM MCU that is packaged in
an opaque plastic package, it is called a “one-time-programmable”
MCU because there is no way to expose the EPROM to a UV light.
PC Abbreviation for program counter CPU register of the M68HC05.
program counter The CPU register that holds the address of the next instruction or
operand that the CPU will use.
RAM Random Access Memory. Any RAM location can be read or
written by the CPU. The contents of a RAM memory location
remain valid until the CPU writes a different value or until power
is turned off.

registers Memory locations that are wired directly into the CPU logic
instead of being part of the addressable memory map. The CPU
always has direct access to the information in these registers. The
CPU registers in t he M68HC05 are A (8-bit accumulator), X (8-bi t
index register), CCR (condition codes register containing the H, I,
N, Z, and C bits), SP (stack pointer), and PC (program counter).
Memory locations that hold status and control information for on-
chip peripherals are called I/O and control registers.
reset Reset is used to force a computer system to a known starting point
and to force on-chip peripherals to known starting conditions.
S-record A Motorola standard format used for object code files.
simulator A computer program that copies the behavior of a real MCU.
source code See source program
SP Abbreviation for stack pointer CPU register in the M68HC05
MCU.
source program A text file containing instruction mnemonics, labels, comments,
and assembler directives. The source file is processed by an
assembler to produce a composite listing and an object file
representation of the program.
stack pointer A CPU register that holds the address of the next available storage
location on the stack.
VDD The positive power supply to a microcontroller (typically 5 volts
dc).
VSS The 0 volt dc power supply return for a microcontroller.
Word A group of binary bits. Some larger computers consider a set of 16
bits to be a work but this is not a universal standard.
XAbbreviation for “index register,” a CPU register in the M68HC05.
Z Abbreviation for “zero,” a bit in the condition codes register of the
M68HC05. A compare instruction subtracts the contents of the
tested value from a register. If the values were equal, the result of
this subtraction would be zero so the Z bit would be set; after a
load accumulator instruction, the Z bit will be set if the loaded
value was $00.
