The 8051
	These notes will not tell you absolutely everything about the 8051 microcontroller. However, we hope they will provide you with a good introduction to this very popular controller. They should help you to start writing simple assembly language programs that you can test on the EdSim51 Simulator.
	For more information on the 8051, a fine book is The 8051 Microcontroller, Third Edition by I. Scott MacKenzie.
