Interfacing is of two types, memory interfacing and i o interfacing. when we are executing any instruction, we need the microprocessor to access the memory for reading instruction codes and the data stored in the memory. I o interfacing is crucial for ensuring effective transfer of data and information between internal and external components of a computing system. in this chapter, we will learn about fundamentals of i o interfacing, its structure, functions, and applications. Learn about io interfacing for intel 8086, including memory mapped vs io mapped io, output input ports, and examples. educational resource for microprocessor architecture. This lecture describes the io interface circuits of an 8086 based microcomputer system. the input output system of the microprocessor allows peripherals to provide data or receive results of processing the data.
