Summary

Ideal for use in microprocessor courses in engineering or computer science, Software and Hardware Engineering: Motorola M68HC12 provides an in-depth, hands-on introduction to the architecture and design of hardware and software for the Motorola M68HC12. · Gives students the tools to use the Motorola M68HC12 in real-world applications · Covers the hardware features of two versions of the M68HC12--the M68HC812A4 and the M68HC912B32 · Compares features common with the Motorola M68HC12's predecessor, the M68HC11 · Incorporates over 100 extensive programming examples · Features chapters on fuzzy logic, programming a fuzzy inference engine, and the Background Debug Module · Includes a detailed appendix covering the design of software for a debugging pod This text can be used with its companion volume, Microcontrollers and Microcomputers: Principles of Software and Hardware Engineering (OUP, 1998), or with any other book that examines the general principles of microcomputer technology. It can also stand alone in a course devoted to the M68HC12. A world wide web site provides additional information including source files for all chapter examples: http://www.coe.montana.edu/ee/cady/books/m68hc12.htm.
