Product Profile
Assembly Language Toolset for
Microcontrollers
Motorola offers an assembly language development toolset that supports the M68HC05,
M68HC08, M68HC11 and M68HC16 microcontrollers. These tools provide a path to higher perfor-
mance while maintaining compatibility with existing software and systems. The tools include: an as-
sembler (masm), linker (ld), Motorola S-record generator (hex), assembly language converter
(i2m), symbol table dump utility (nm), map file generator (mlst2map), conversion utility to support
the CDS805 (coff2cds), and symbol table reduction tool (strip). This toolset operates under DOS on
IBM PC and 100% compatible machines which contain an Intel 80386 or higher microprocessor.
Features include:
• Relocatable or absolute object modules
• Switch selectable processor support
• Full instruction sets
• Common syntax and extended instructions to ease upward migration
• All available addressing modes
• Full macro capability with nesting
• Include file support that allows nested include files
• Linking of multiple source files
• Optimization of long and short branches
• Generation of Motorola S-records
• 128 character symbol names
• Partial linking
• Common Object File Format
• User-controlled assembly listings
• Cross reference listings
• Symbol table listings
• User-selectable case sensitive labels
• Motorola’s Assembly Language Input standard is based on MASM
• Works with existing CDS805 hardware and software
• Works with existing MMDS05, MMDS08 and MMDS11 hardware and software and will work
with planned upgrades
• User-selectable option to minimize the size of the symbol table to decrease download time
• Absolute listings available after relocation
• Creation of map files

The Assembly Language Development Toolset comes in a shrink-wrapped package that includes:
• User’s Manual
• Release Guide
• License Agreement
• One 3.5 inch DSHD disk (1.44 Mbyte)
The release guide includes phone and fax numbers and an Internet address for technical support.
Software
Many controller applications are severely limited by the cost of additional memory components or
by timing constraints, therefore, they cannot take advantage of the benefits offered by high-level
languages. Other applications which use high-level languages often need the speed, access to spe-
cial instructions, and unique memory optimizations that are available only through low-level lan-
guages, such as Motorola’s macro assembler. This toolset provides capabilities to engineer
solutions to these problems.

These tools place few restrictions on the application. Some examples of the freedom allowed are:
symbol names up to 128 characters, 32 Kbyte symbols per source file, 256 sections, nested macros
and nested include files to 256 levels, and evaluation of all expressions using 32-bit arithmetic.
With the linker, a user arranges program sections to fit into physical memory. Sections can be con-
tained in one or more files facilitating rapid development and debugging. A user-defined directive
file instructs the linker where to place these sections. Additionally, the linker supports solutions to
more advanced problems, such as, partial linking and source level debugging.
Individual microcontroller instruction sets and addressing modes are optimized for high perfor-
mance. Motorola’s macro assembler supports the instruction sets of all our controllers with a com-
mon syntax and with language extensions that ease the upward migration path without sacrificing
any of the speed or efficient memory utilization benefits that assembly language provides.
