In immediate addressing mode, as the name implies, when the instruction is assembled, the operand comes immediately after the opcode. Notice that the immediate data must be preceded by the pound sign, “#”. This addressing mode can be used to load information into any of the registers, including the DPTR register.

What is an immediate addressing?

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.

What is immediate addressing mode give an example?

In immediate addressing mode the source operand is always data. If the data is 8-bit, then the instruction will be of 2 bytes, if the data is of 16-bit then the instruction will be of 3 bytes. Examples: MVI B 45 (move the data 45H immediately to register B)
