📖 The 5 Addressing Modes of Intel 8085

1. Immediate

Operand data is specified directly within the instruction bytes.

MVI A, 45H
LXI H, 2000H

2. Register

Data is transferred or manipulated solely between CPU registers.

MOV A, B
ADD C

3. Direct

The exact 16-bit memory address is explicitly embedded in operand bytes.

LDA 2050H
STA 3000H

4. Reg Indirect

The memory address is held inside a 16-bit register pair (e.g. HL as M).

MOV A, M
STAX B

5. Implied

The operand is implicitly defined by the opcode itself.

CMA
RAL / HLT
