son, before applying Bass & Treble Control, the
user has to set the TONE_ATTEN register to the
maximum value of enhancement is going to per-
form.
For example, in case of a 0 dB signal (max. level)
only attenuation would be possible. If enhance-
ment is desired, the signal has to be attenuated
accordingly before in order to reserve a margin in dB.
An increment of a decimal unit corresponds to a Tone
Attenuation step of 1.5dB.
