Microphone supply voltage control status.
0 Supply voltage was set to a constant value.
2 Supply voltage state is controlled by the ME and depends on parameter data
set of the selected audio mode.
Notes
• The programmable power supply of the VMIC line gives you greater flexibility in connecting audio accessories
or using the two analog audio interfaces for a variety of functions other than audio. A detailed description of
the extended usage of the analog audio interfaces can be found in [9].
• During an active call, users should be aware that when they switch back and forth between different audio
modes (for example handsfree on/off) the value of <MicSwitch> does not change, i.e. the microphone mode
is retained until explicitly changed.
