Multi purpose output
A 2-bit value to select the output signal on pin STATUS.
Table 34 Multi purpose output selection
9.16
Mode
A 2-bit value to program the mode of the sound processing
filters of bass boost and treble.
Table 35 Flat/min./max. switch position
9.17
Bass boost
A 4-bit value to program the bass boost settings. The used
set depends on the setting of bits M1 and M0.
At fs = 44.1 kHz the 3 dB point for minimum setting is
250 Hz and the
3 dB point for maximum setting is 300 Hz.
The default value is 0000.

9.18
Treble
A 2-bit value to program the treble setting. The used set
depends on the setting of bits M1 and M0. At fs = 44.1 kHz
the
3 dB point for minimum setting is 3.0 kHz and the
3 dB point for maximum setting is 1.5 kHz. The default
value is 00.
