The compiler is writtent to support the chip. For details of the compiler specifics, you must read the compiler Manual - the relevant section here is: http://www.keil.com/support/m...mareas.htm The chip has several addressing modes and memory areas. Some overlap others do not. For general details of the 8051 architecture, you must read the so-called "bible" for the 8051. Erik has already given the links once, but here they are again: Chapter 1 - 80C51 Family Architecture: http://www.nxp.com/acrobat_d...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.nxp.com/acrobat_d...UIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.nxp.com/acrobat_d...WARE_1.pdf For specific details of the particular chip, you will also have to read the Datasheet |
