In this book, the author provides a comprehensive treatment of the MCS-51 microcontroller. Huang covers the full spectrum of I/O functions of the MCS-52 variants; by progresively developing topics, starting with the simple and moving to the complex, he strikes a balanced introduction to the theoretical topics and the design and implementation issues of the MCS-51 microcontroller. The book starts wit the MCS-51 CPU architecture and programming model and then progresses toward every I/O function. In each I/O function, the author first presents the general issue and then details the specifics of the MCS-51. Numerous design examples and exercises illustrate the concepts presented and helps readers grasp the key concepts and learn the applications. The book is an ideal introduction to microcontroller and microprocessor based design, while containing enough rigour and depth to provide in depth knowledge of the MCS-51 microcontroller. It is intended as a textbook for a first course on microprocessors or microcontrollers, but is also suitable for anyone who needs to learn about the MCS-51 microcontroller. It includes a supplemental CD and will also have a solutions manual available only to adopters of the text.
