MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Immediate-Immediate addressing is not really an addressing mode into memory; rather, it is an instruction format that directly includes the data to be acted on as part of the instruction. This form of operand access simplifies the instruction execution cycle since no additional fetches are required.

Detailed explanation-2: -Immediate addressing mode The instruction is 2 bytes when there is 8-bit data and 4 bytes when there is 16-bit data. Examples of instructions that use immediate addressing mode are: MVI B 05 – This instruction transfers the data, that is 05, to register B.

Detailed explanation-3: -Immediate addressing mode: It is the simplest form of addressing mode, in which the operand value is present in the instruction. This mode is used to define and use constants or set initial values of variable. In this, no memory reference other than the instruction fetch is required to obtain the operand.
