Addressing modes of 8085A microprocessor?

In: Intel 8085 [Edit categories]

Answer:

ADDRESSING MODES for 8085

1. Immediate addressing.

2. Register addressing.

3. Direct addressing.

4. Indirect addressing.

Immediate addressing

Load the immediate data into the register, R.

Example: MVI R,data

Register addressing

Data from source register is moved into destination register.

Example: MOV Rd, Rs

Direct addressing

Accepts data from external devices to be stored in the accumulator or sends the data from the accumulator to the external device.

Example: IN 00H or OUT 01H

Indirect Addressing

Here the Effective Address is calculated by the processor. And the contents of the address is used as a second address. At the second address the data is stored.

Relevant answers:

What are the addressing mode in microprocessor?
What microprocessor? It matters.
What is the addressing mode of DAA in 8085 microprocessor?
The DAA instruction in the 8085 only accesses internal registers, so it has no addressing mode. At best, it can be considered an implicit mode instruction.
What is the addressing mode used in MVI in 8085 microprocessor?
The MVI instruction is Move Immediate. It uses immediate mode addressing, meaning that the operand is contained within the instruction, i.e. immediately following it.
What is the addressing mode of the instruction PCHL in 8085 microprocessor?
It is register addressing mode, as it moves the content of HL to PC which is data and not address.
Difference between direct addressing mode and indirect addressing modein8085 microprocessor?
Direct addressing is used to access the SFRs whereas indirect addressing is used to access the RAM space shared by these SFRs with the scratchpad RAM.
