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.

However , when it is used as a counter , it is a pulse outside of the 8051 that increments the TH , TL registers . In counter mode , notice that the TMOD and TH , TL registers are the same as for the timer discussed in the last section ...
Example 9-18 Assuming that clock pulses are fed into pin Ti , write a program for counter 1 in mode 2 to count the pulses and display the state of the TL1 count on P2 . Solution : MOV TMOD , # 01100000B AGAIN : BACK : MOV TH1 , # 0 SETB ...
Then send a high - to - low pulse to the E pin to enable the internal latch of the LCD . This is shown in the code below . See Figure 12-2 . ; calls a time delay before sending next data / command ; P1.0 - P1.7 are connected to LCD data ...
