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 MICP2 line gives you greater flexibility in connecting audio accesso-

ries or using MICP2 for a variety of functions other than audio. A detailed description of the extended usage

of MICP2 can be found in [8].

• 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.
