Question

Write a program to move a bit at address
22H to bit 2 of Accumulator

Answer 1

To move a bit at address 22H to bit 2 of the Accumulator in a program, use bitwise operators.

Step-by-step explanation:

To move a bit at address 22H to bit 2 of the Accumulator in a program, you would need to use bitwise operators. Here is an example program in Assembly language:

MOV A, [22H] ; Move the value at address 22H to the Accumulator
LCR A, 2 ; Left circular rotate the Accumulator by two bits
MOV [22H], A ; Move the updated Accumulator value back to address 22H

In this example, the first line moves the value from address 22H to the Accumulator. The second line rotates the Accumulator to the left by two bits, moving the desired bit to bit 2. Finally, the third line moves the updated Accumulator value back to address 22H.
