Editing Instruction set architecture (section)

====Data handling and memory operations====
*''Set'' a [[processor register|register]] to a fixed constant value.
*''Copy'' data from a memory location or a register to a memory location or a register (a machine instruction is often called ''move''; however, the term is misleading). They are used to store the contents of a register, the contents of another memory location or the result of a computation, or to retrieve stored data to perform a computation on it later. They are often called [[load–store unit|''load'' or ''store'']] operations.
*''Read'' or ''write'' data from hardware devices.
