#83128 - RTFM! Responding to: ???'s previous message |
For fundamental issues like this, you need to read the documents commonly known as the "bible" for the 8051:
here are the links to "the bible" Chapter 1 http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf chapter 2 http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf chapter 3 http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf "Memory Organisation" is right at the start of Chapter 1 (80C51 Family Architecture) - including schematics; "Accessing External Memory" starts on p6 of Chapter 3 (the 80C51 family hardware description); Chapter 2 is a complete, detailed description of the 8051 Instruction Set. |
