Question

What will be the output after executing the following instructions? MOV A, #55 ANL A, #67

Answer 1

Answer:

sorry I can't understand

Answer 2

The output after executing the following instructions will be 45.

1. After executing the first instruction, 55 is stored in accumulator A.

2. After executing the second instruction, bitwise AND operation is performed between the data stored in A and 67. ANL performs bitwise AND operation between the two operands and the result is stored in the accumulator.

3.  55 = 0101 0101

    67 = 0110  0111

           0100 0101

  0100 0101 = 45

Hence, the output will be 45, which is stored in accumulator A.
