Intel's 8051 hardware documentation
Get this if you want to use 8051 to the fullest extent. The tutorial
that is included here (at 8052.com) only covers enough to get you started
in some programs. After reading this document, you will discover how to
make the interrupt pin edge-triggered instead of level triggered, and
much more. It will also show you what values each register contains upon
reset. It is a very helpful document, and well worth the look.
The link will take you to Intel's site where you can download the file.
It is about 15MB, so it will take about 40 minutes on a dial-up connection.
