Addressing modes of the 8085 microprocessor

Briefly describe all the addressing modes of the 8085 microprocessor with the aid of examples?




The different kinds of addressing modes of the 8085 are illustrated below:

  • Direct addressing: The instructions in it hold the operand. For instance: STA5513H or in or out instructions like IN PORT C.
  • Register addressing: The common reason registers hold the operands. For instance: MOV A, B;
  • Register indirect addressing: This includes the employ of register pairs in place of a single register. For instance: M, MOV A; ADD M.
  • Instantaneous addressing: The instance are07, MVI A; or ADI 0F and so on.
  • Implicit addressing: this type of addressing holds no operands. For instance: CMA, RAR and so forth.
