Addressing mode

Part of the instruction architecture in most processors that determines how machine language instructions find the data they need.

Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. Addressing modes define how the machine language instructions in that architecture identify the operand(s) of each instruction.

From Wikipedia

Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. Addressing modes define how the machine language instructions in that architecture identify the operand(s) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere. In computer programming, addressing modes are primarily of interest to those who write in assembly languages and to compiler writers. For a related concept see orthogonal instruction set which deals with the ability of any instruction to use any addressing mode.
