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.

There is a register called IE ( interrupt enable ) that is responsible for enabling ( unmasking ) and disabling ( masking ) the interrupts . Figure 11-2 shows the IE register . Note that IE is a bit - addressable register .
Sometimes the chip select is also referred to as chip enable ( CE ) . In connecting a memory chip to the CPU , note the following points . 1. The data bus of the CPU is connected directly to the data pins of the memory chip . 2.
As shown in Figure control C - 9 a tri - state buffer has a ( active high ) single input and single output and the enable control input . By activating the enable , data at the input is H H ( c ) transferred to the output .
