source to the Input Mixer. Each step corresponds to 3 dB gain adjustment, with 0000 = 0 dB.
The total range is 0 dB to -45 dB attenuation.
the Input Mixer. Each step corresponds to 1.5 dB gain adjustment, with 01000 = 0 dB. The
total range is +12 dB to -34.5 dB attenuation. See Table 7 on page 31 for further attenuation
levels.
PC_BEEP Mute. Setting this bit mutes the PC_BEEP input signal.
PC_BEEP Volume Control. The PV[3:0] bits control the gain levels of the PC_BEEP input
0000h. This value corresponds to 0 dB attenuation and Mute ‘clear’.
Phone Mute. Setting this bit mutes the Phone input signal.
Phone Volume Control. The GN[4:0] bits control the gain level of the Phone input source to
8008h. This value corresponds to 0 dB attenuation and Mute ‘set’.
