Description
Device identification.
Port-D pin drivers. Typically used as rear panel line output.
Port-A pin drivers. Typically used as front panel headphone output.
Monaural output pin driver. Typically used to drive an internal
speaker or as a microphone selector on a telephony system.
Port-B pin drivers. Typically used as front panel microphone.
Port-C pin drivers. Typically used as rear panel line input.
S/PDIF output digital interface.
Chooses which signals drive the monaural output mixer and pin.
Allows selective mixing of the front/rear microphone sources to a
single combined signal.
Selects between the digital beep generator and the analog PC BEEP pin
as the source for the analog mixer.
Stereo-to-monaural mixer for MONO_OUT.
Individual gain control for the Port-B (front microphone) input to the
analog mixer.
Individual gain control for the Port-C (line in) input to the analog
mixer.
Power control on the analog mixer and associated amplifiers.
Chooses which signal is recorded by the record ADC. Also contains
the record gain controls.
Analog PC Beep in pin drivers. This signal is coupled to the outputs
while the codec is held in reset. This may be selected as an input to
the analog mixer after reset has been released.
Port-E pin drivers. Typically used as auxiliary input.
Port-F pin drivers. Typically used as rear panel microphone.
CD in pin drivers.
Individual gain control for the Port D (front) input to the analog
mixer.
Individual gain control for the Port E (aux) input to the analog mixer.
Individual gain control for the Port F (rear microphone) input to the
analog mixer.
Mute control for Port B (front microphone) into microphone mixer.
Mute control for Port F (rear microphone) into the microphone mixer.
