Prentice Hall, 2000 - Digital control systems - 435 pages
For courses teaching the 8051 Microcontoller.
This book uses a step-by-step approach to teach the fundamentals of assembly language programming and interfacing of the 8051 microcontroller. It uses many examples to clarify concepts. Simple, concise examples are utilized to show what action each instruction performs, then a sample is provided to show its application. This text provides a comprehensive understanding of the internal organization of the 8051 registers and resources in a way that sheds the student's fear of assembly language. Whether students become designers of stand-alone systems or complex embedded systems, they will find this text a useful resource.

SUMMARY This chapter discussed the role and importance of microcontrollers in everyday life . Microprocessors and microcontrollers were contrasted and com- pared . We discussed the use of microcontrollers in the embedded market .
In other words , when the 8031 is connected to external memory , P2 is used for the upper 8 bits of the 16 - bit address , and it can- not be used for I / O . This is discussed in detail in Chapter 14 . From the discussion so far ...
Signed num- bers are discussed in Section 6.3 . SECTION 6.1 : UNSIGNED ADDITION AND SUBTRACTION Unsigned numbers are defined as data in which all the bits are used to rep- resent data , and no bits are set aside for the positive or ...
