WebMemory mapped I/O. Memory mapped I/O is an interfacing technique in which memory related instructions are used for data transfer and the device is identified by a 16-bit address. In this type, the I/O devices are treated as memory locations. The control signals used are MEMR and MEMW. The interfacing between I/O and microprocessor will be … WebI/O subsystem ¶. 10.1. Introduction ¶. .intro: This document is the design of the MPS I/O Subsystem, a part of the plinth. .readership: This document is intended for MPS developers. 10.2.
