Detailed explanation-1: -Indirect addressing mode, the data to be operated is available inside a memory location and that memory location is directly specified as an operand. The operand is directly available in the instruction itself.
Detailed explanation-2: -Indirect Addressing Indirect addressing mode uses instructions that include the address of a value that points to the effective address of the operand.
Detailed explanation-3: -The direct addressing mode contains the concerned operand in the instruction code’s address field. In the case of an indirect addressing mode, the operand’s address stays in the address field of any instruction. Total number of Memory References.
