A logical-AND is performed between the contents of the operand<br />

and the contents of the A register. The result is placed in the A<br />

register. If the same bit position of the operand and the A<br />

register contains a one, the result is one; otherwise, the result<br />

is zero. The truth table is shown below, where n = bit position.<br />
