FAQs-Register indirect addressing mode in 8085 Microprocessor

What is Effective Address?

The address where the operand is stored is called the effective address.

What is Addressing Mode?

The addressing modes defines and specifies the data on which the operations are to be performed. These addressing modes tell us about the operand in which the desired operation is performed.

What are the Addressing Modes in 8085 Microprocessor?

The different addressing modes in 8085 microprocessors are:

  • Immediate Addressing Mode
  • Register Addressing Mode
  • Direct Addressing Mode
  • Register Indirect Addressing Mode
  • Implied Addressing Mode
  • Relative Addressing Mode

Register indirect addressing mode in 8085 Microprocessor

Register indirect mode in 8085 microprocessors is an addressing mode in which the address part of the instruction specifies the address of the register, and the register holds the effective address of the operand. The operand is present in the effective address specified by the register. In this article, we will explore register indirect addressing mode in 8085 microprocessors in detail along with examples. Also, we will discuss the advantages and disadvantages and applications of register indirect addressing modes.
