Address bits are Read Lock bit locations and Even Address bits are Write

Lock bit locations. The most significant (left-most) bit indicates the sign of

the integer; it is sometimes called the sign bit. If the sign bit is zero, then

the number is greater than or equal to zero, or positive. If the sign bit is

one then the number is less than zero or negative.
