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.
