sponds to 1.5 dB gain adjustment, with a total available range from 0 dB to -46.5 dB attenu-
ation. Setting the MM5 bit sets the mono attenuation to -46.5 dB by forcing MM[4:0] to a ‘1’
state. MM[5:0] will read back 011111 when MM5 has been ‘set’. See Table 4 on page 27 for
further attenuation levels.
step corresponds to 1.5 dB gain adjustment, with a total available range from +10.5 dB to
-10.5 dB gain. See Table 5 for further details. The center frequency from which the gain is
measured defaults to 100 Hz for bass, and may be changed using the LPFS[1:0] bits in the
Signal Processing Engine Control Register (Index 6Eh, Address 08h).
step corresponds to 1.5 dB gain adjustment, with a total available range from +10.5 dB to
-10.5 dB gain. See Table 5 for further details. The center frequency from which the gain is
measured defaults to 10 kHz for treble, and may be changed using the HPFS[1:0] bits in the
Signal Processing Engine Control Register (Index 6Eh, Address 08h).
Mono Mute. Setting this bit mutes the MONO_OUT output signal.
Mono Volume Control. The MM[5:0] bits control the mono output volume. Each step corre-
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
Bass Control. The BA[3:0] bits are used to control the bass gain in the effects engine. Each
Treble Control. The TR[3:0] bits are used to control the treble gain in the effects engine. Each
0F0Fh. This value corresponds to bypass of bass and treble gain.
