MOV A, #2BH

ORL A, 00H

Choose the right answer to the question The contents of the accumulator after this operation from the following options and a detailed explanation.

  1. 1B H
  2. 2B H
  3. 3B H
  4. 4B H

Answer - B.  2B H

The answer to the question, The contents of the accumulator after this operation, is 2B H. 

Solution

The detailed solution to the question of The contents of the accumulator after this operation is provided here. 

  • ‘#’ refers to a specified value, and ‘H’ refers to the specified value being in hexadecimal format.
  • The instruction MOV stores the value directly specified or via indirect addressing in the destination register specified within the instruction.

MOV A,#2BH – stores 2B in register A (16-bit).

  • The instruction ORL performs bitwise OR operation on the operands and stores the result in the destination operand.

ORL A,#00H – perform the bitwise operation on the content stored in A and 00.

Stepwise operation is shown below

MOV A,#2BH
ORL A,#00H

Therefore, the contents of the accumulator after the operation will be 2B.

Hence, option (B) is correct.
