Note: The slice level defined by Register 22 and 21 gets updated together after Register 21, the

least significant byte of the 16-bit field, has been written. Prior to writing Register 21, the
value written to Register 22 is stored into a mirroring register first. Any read to Register 22
prior to writing Register 21 will not return the intended value.
