This chapter outlines some of the basic methods of communications, both serial and parallel, between humans or machines and the microprocessor. In this chapter, we first introduce the basic I/O interface and discuss decoding for I/O de- vices. Then, we provide detail on parallel and serial interfacing, both of which have a
28 Oct 2009 Interfacing is one of the important concepts in microprocessors engineering. A microprocessor can contact the external world only through interfacing. Learn about the various types of interfacing which includes Memory interfacing and I/O interfacing. Also learn about the serial and parallel communication

To make students understand the basic concept of traffic light controller. 4. There are two ways to interface 8085 with I/O devices in parallel data transfer mode:.
Focus on microprocessors as general purpose, flexible and reconfigurable controllers and the ways sensors and actuator relate to these. Microprocessors . Interfacing Issues. Three basic modes: 1. Continuous dedicated monitoring of the sensor by the microprocessor; 2. Polling the sensor; 3. Interrupt mode. Continuous
Intel 8085 is an 8-bit, NMOS microprocessor. It is a 40 pin I.C package fabricated on a single LSI chip. The Intel. 8085 uses a single + 5V d.c supply for its operation. Its clock speed is about 3 MHz. The clock cycle is of 320ns. It has 80 basic instructions and 246 opcodes. Figure(3.2) shows the functional block diagram of Intel.
