Functional Description
This is a mono input which gets summed into the stereo line output after the National 3D Sound
block. The PC_BEEP level can be adjusted from 0dB to −45dB in 3dB steps, or muted, via register
0Ah.
This is a mono input which gets summed into the stereo line output after the National 3D Sound
block. The PHONE level can be adjusted from +12dB to −34.5dB in 1.5dB steps as well as muted
via register 0Ch.
This line level input can be routed through the input mux and recorded by the left ADC. In addition,
this analog input gets summed into the left output stream. The amount of CD_L signal mixed in the
left output stream can be adjusted from +12dB to −34.5dB in 1.5dB steps as well as muted via
register 12h.
