Signed number (2 complement)
This register is used to select the enhancement
or attenuation STA013 has to perform on Treble
Frequency range at the digital signal.
A decrement (increment) of a decimal unit corre-
sponds to a step of attenuation (enhancement) of
1.5dB.
The allowed Attenuation/Enhancement range is
[-18dB, +18dB].
