PC_BEEP Volume Register (Index 0Ah)
Mute
PC_BEEP Mute. Setting this bit mutes the PC_BEEP input signal.
PV[3:0]
PC_BEEP Volume Control. The PV[3:0] bits are used to control the gain levels of the PC_BEEP
input 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.
Default
0000h. This value corresponds to 0 dB attenuation and Mute ‘clear’.
This register has no effect on the PC_BEEP volume during RESET#.
4.6
Phone Volume Register (Index 0Ch)
Mute
Phone Mute. Setting this bit mutes the Phone input signal.
GN[4:0]
Phone Volume Control. The GN[4:0] bits are used to control the gain levels of the Phone input
source to 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 gain. See Table 4 on page 24 for further details.
Default
8008h. This value corresponds to 0 dB gain and Mute ‘set’.
