In this chapter, we will discuss Memory Interfacing and IO Interfacing with 8085. Interface is the path for communication between two components. Interfacing is of two types, memory interfacing and I/O interfacing. When we are executing any instruction, we need the microprocessor to access the. I/O Interfacing − Overview. It is a specially designed microprocessor having a local memory of its own, which is used to control I/O devices with minimum CPU involvement. Microprocessors 14 8085 is pronounced as 'eighty-eighty-five' microprocessor. It is an 8-bit microprocessor.
