3. TECHNICAL BRIEF

3.8 Headset Interface

This phone has 4 electrodes such as GND, AUXIP, AUXIN, nJACK_DET.

Switching from Receiver to Headset Jack

If jack is inserted, JACK_DETECT goes from high to low.

Audio path is switched from receiver to earphone by JACK_DETECT interrupt.

Switching from Headset Jack to Receiver

If jack is removed, JACK_DETECT goes from low to high.

Audio path is switched from earphone to receiver by JACK_DETECT interrupt.
