Operations of Immediate Addressing Mode
We know that in immediate addressing mode the operand in present in the instruction only as an immediate value. So, to perform any operation on the operand we directly fetch the operand from the source address field of the instruction. Consider the instruction format given below.

Consider an example instruction.
MOV AL, 20H
Operations performed while executing the above instruction is given below.
AL ← 20H
Immediate Addressing Mode in 8086 Microprocessor
Immediate addressing mode in 8086 microprocessor contains the instruction where the first operand may be a register or memory location and the second operand is an immediate value that represents the operand. In this article, we will explore the immediate addressing mode in detail along with the examples of immediate addressing mode. Also, we will discuss the advantages and disadvantages and applications of immediate addressing mode.
