The 8051 Microcontroller and Embedded Systems, Volume 1
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.

This function can be used to compare two bits to see if they are the same . NAND and NOR gates The NAND gate functions like an AND gate with an inverter on the output . It produces a zero out- put when all inputs are 1 ; otherwise , it ...
It is the function of the CPU to fetch these instruc- tions from memory and execute them . To perform the actions of fetch and execute , all CPUs are equipped with resources such as the following : 1. Foremost among the resources at the ...
As shown in Figure 4-1 , Port 2 is also designated as A8 - A15 , indicating its dual function . Since an 8031 is capable of accessing 64K bytes of external memory , it needs a path for the 16 bits of the address .
