QThis register contains a 16-bit signed (2’s compliment) number. Positive values have the most
significant bit clear and have the same magnitude as an unsigned integer. Negative values have the
most significant bit set. The magnitude of a negative value is found by complimenting (inverting)
all of the bits and adding 1.
