APPENDIX B
DEVELOPMENT TOOLS AND SUPPORT
B.1 SOFTWARE OVERVIEW
The software development package is offered as a set of independent mod-
ules which provide the following features:
• IMP Chip Evaluation
By running the modules on the development board described in
B.4
ADS302 DEVELOPMENT SYSTEM, it is possible to examine and eval-
uate the MC68302. Symbolic, user-friendly menus allow control of all
parts of the IMP.
• IMP Chip Drivers
Written in C, the source code of the IMP drivers is available as a doc-
ument or on electronic media.
• Protocol Implementations
Modules implementing common ISO/OSI layer 2 and 3 protocols are
available under license. These are in the form of binary relocatable
object code as well as source code written in C.
• Portability
All of the modules may be easily ported to different MC68302 imple-
mentations and combined with user-developed code. Well-defined
software interface documentation is available for all provided modules.
B.2 SOFTWARE MODULES
Since the IMP is a memory-mapped device based on a full M68000 core,
existing compilers, assemblers, and linkers designed for the M68000 Family
may be successfully used. The memory address space for the IMP is relo-
catable (through the base address register) to any 4K-byte contiguous space
in the M68000 processor memory map, allowing the IMP registers to be
mapped to any location in system RAM.
Chip driver routines written in C illustrate initialization of the IMP, interrupt
handling, and the management of data transmission and reception on all
channels.
