Mono/Stereo Mic Volume (0Eh)
Mic is actually one of 6 possible stereo input sources selected by the MicMux (Reg 66h, Page 0, Bits
D2:D0). Each of these sources may be selected as mono Left, mono Right, stereo, or stereo L-R
swapped. Boosts of 10, 20, or 30dB are available to all inputs controlled by the microphone mux.
8.2.8.1.
Enabled when Stereo Mic Enable Bit (STMICEN), Reg 72h, Page 0, Bit D0 = 0
Default: 8008h.

Mutes Left and Right Channel Mic
0 = no mute

Mutes Right Channel independent of Left Channel
0 = unmute
1 = muted
The SPLITMUTE bit (Reg 72, Page 0, Bit D6) and STMICEN bit (Reg 72,
Page 0, Bit D0) must both be set to 1 in order for the RMute bit to have an
effect on the sound.
The RMute bit is R/W. The RMute bit may be written and read regardless
of the state of the SPLITMUTE and STMICEN bits.
Works with MICGAINVAL (Register 6Eh, Bit D2)
