For a second microprocessor course for students enrolled in Electrical/Computer Engineering Microcontroller
courses.
Designed for a senior- or graduate-level embedded systems design course, Embedded Systems Design and Applications
with the 68HC12 introduces readers to unique issues associated with designing, testing, integrating, and implementing
microcontroller/microprocessor-based embedded systems.
