The 8051 Microcontroller and Embedded Systems, Volume 1
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.

Example 5-7 Assuming that ROM space starting at 250H contains “ America ” , write a program to transfer the bytes into RAM locations starting at 40H . Solution : ; ( a ) This method uses a counter ORG 0000 MOV DPTR , #MYDATA ; LOAD ROM ...
SECTION 14.4 : 8051 DATA MEMORY SPACE So far in this book all our discussion about memory space has involved program code . We have stated that the program counter in the 8051 is 16 - bit and therefore can access up to 64K bytes of ...
For example , the space 0000 - 7FFFH is allocated to program code , and address space DOOOH - FFFFH is set aside for data . In accessing the data , we use the MOVX instruction . How do we connect the PSEN and RD signals to such a ROM ?
