Various Addressing Modes of 8085 or 8085A Microprocessor

:Addressing Modes of 8085 Micro Processor:

Addressing modes are the ways by which the data is transmitted from one register to another register, from the memory to the register, and from the register to the memory without any alteration(changes) in the content or we can say that it is the way of  specifying data to be operated by an instruction is called addressing modes.

Here, 8085 µP contains 5 types of addressing modes:

• Immediate Addressing Mode.
• Register Addressing Mode.
• Direct Addressing Mode.
• Register Indirect Addressing Mode.
• Implied/Implicit Addressing Mode.

#Immediate Addressing Mode: In this addressing mode, data is directly specified within the instruction itself.

e.g.

#Register Addressing Mode: In this addressing mode, data is transmitted from 1 register to the 2nd register.

e.g.

#Direct Addressing Mode: In this addressing mode, data is transmitted from a specified memory location to the register.

e.g.

#Register Indirect Addressing Mode: In this addressing mode, data is transmitted from 1 register to the 2nd register but indirectly. Here, data is transmitted from a memory location to a register whereas the memory location is pointing to another register.

e.g.

#Implied/Implicit Addressing Mode: In this addressing mode, the operation or data is specified within the opcode of the instruction itself. We do not require any other operand for such type of addressing.
