Description
This register is an 8 bit and loaded with the value
of PCM scale.
PCM scale is a master scale factor. It is expressed
in 2 dB attenuation.
Attenuation =-2k dB (where k is the register con-
tent). When k=0 the attenuation is not exactly 0 dB
but it corresponds to a scale of 255/256.

Description
This register is an 8 bit signed byte register (-128,
+127) and controls the Left/Right channel balance.
When the value is positive the Left channel is at-
tenuated, when the value is negative the right
channel is attenuated. The attenuation is done in
steps of 0.5 dB.
