bit[15:8]
Higher resolution is possible: an LSB step in the normal range results in a gain
step of about 1/8 dB, in the extended range about 1/4 dB.
With positive bass settings, internal clipping may occur even with overall volume
less than 0 dB. This will lead to a clipped output signal. Therefore, it is not rec-
ommended to set bass to a value that, in conjunction with volume, would result
in an overall positive gain.
