Detailed explanation-1: -In this addressing mode, The address field of the instruction specifies the address of memory location that contains the effective address of the operand. Two references to memory are required to fetch the operand.
Detailed explanation-2: -The available instruction in a register indirect addressing mode defines that register in the CPU whose contents provide the operand’s address in the memory. In simpler words, any selected register would include the address of an operand instead of the operand itself.
Detailed explanation-3: -Explanation: Absolute mode: In this addressing mode, the address of location of the operand is given explicitly as a part of the instruction. This addressing mode is also known as direct addressing mode.
Detailed explanation-4: -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. It requires no memory references for accessing the data.
