WebThe address of the operand is obtained by adding to the contents of the general register (called index register) a constant value. The number of the index register and the constant value are included in the instruction code. Index Mode is used to access an array whose elements are in successive memory locations. The content of the WebThis instruction uses displacement addressing mode. The instruction is interpreted as 0 + [R d ] ← 20. Value of the destination address = 0 + [R d] = 0 + 1001 = 1001. Thus, value = 20 is moved to the memory location 1001. Thus, After the program execution is completed, memory location 1001 has value 20. sanc application form for community service
