Microprocessors and Microcomputers

Using the currently popular, powerful, yet easy to understand Motorola 68HC11 microcontroller as a representative example, this text provides a comprehensive introduction to the concepts, principles, and techniques of microprocessors and microprocessor-based systems. This edition focuses on the elements and features of the 68HC11 microcontroller IC one of the most powerful and flexible 8-bit microprocessors in general use today as a representative device for teaching/learning microprocessor principles and concepts. This edition features added, expanded or updated coverage of: negation and overflow; IEEE/ ANSI logic symbol standards; databus concepts and operations; memory types, including flash memory, and DRAM operation and refreshing; microprogramming, microcontrollers, and assemblers; reset operation, on-chip memory and I/O ports, and 4K pages; two-operand ALU operations; MPU reset operation, including Computer Operating Properly (COP) Reset and Clock Monitor Reset; multiplication and division instructions; on-chip timer system; programmed time intervals; on-chip A/D converter system; and wide range of on-chip control registers.
