Book excerpt: This book has been written for a diverse audience, primarily for those who work in the area of the electronic design and assembly language programming of small, dedicated computers. An extensive knowledge of electronics is not required to program the microcontroller. A microcontroller is a true computer on a chip, incorporating all the features found in a microprocessor CPU. A microcontroller is a general-purpose device, but one which is meant to fetch data, perform limited calculations on that data, and control its environment based on those calculations. The prime use of a microcontroller is to control the operation of a machine using a fixed program that is stored in ROM and that does not change over the lifetime of the system.
