TX Audio Path
Microphone
An audio signal from microphone is input to pin 14 (MIC+) and pin 13(MIC-) of IC.
In IC1, the audio signal is converted from the analog signal to ADPCM, then to burst data, and sent to RF cricuit.
The stabilized supply voltage is fed to the microphone from pin 17 (MPWR) of IC1.
To reduce consumption current, this voltage is supplied only while calling or receiving.

IC1.
Headset detection
When a headset is inserted, pin 89 (USB_DP/GPI29) of IC100 goes from High to Low and BBIC (IC100) detects the insertion of
the headset.

RX Audio Path
Receiver
Burst data is input from RF cricuit to IC1.
In IC1, the burst data is converted to ADPCM, then to analog signal, and sent from pin 21 (HSSPOUTP) and pin 22 (LOUT) to
the receiver via headset jack (CN301) .
