AV connector

The AV connector handles audio signals output and input. It has audio left and right signals separately (pins
4 and 5) and microphone signals wired to pin 3.
The plug detection signal handles the AV connector plug detection with HeadDet signal from EM ASIC.

Bluetooth interface

Bluetooth provides a fully digital link for communication between a master unit (the phone) and one or more
slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the
BTHFM module.
Bluetooth is physically integrated with FM radio in the BTHFM module ASIC, but from a functional point of
view they have nothing in common
