WebFigure 3: General external memory interfacing [1] Important pins for interfacing the memory are ALE, Read/Write, Address lines (AD0-AD7). ALE is used for latching the address to the memory at T1 state of the clock. If ALE is ‘1’ or high then address will be latched to the memory.
Web1. Memory Interfacing: Memory is an integral part of a microprocessor system, and in this section, we will discuss how to interface a memory device with the microprocessor. The Memory Interfacing in 8085 is used to access memory quite frequently to read instruction codes and data stored in memory. terminex policy on non effective treatmentWebPORT P1: This port is used for various interfacing activities. This 8-bit port is a normal I/O port i.e. it does not perform dual functions. PORT P2: Similar to PORT P0, this port can be used as a general purpose port when there is no external memory but when external memory is present it works in conjunction with PORT PO as an address bus. tricity bendix 46cm cookerWeb5 feb. 2024 · Memory Interfacing.
