Acc_Det pin connection
The Acc_Det pin (accessory detection) is an input pin for the audio pre-amplifier chip which
detects the voltage of the microphone line MIC2P in case the user presses the on-hook/off-
hook button on the headset. When the user selects off-hook using the headset button, the
MIC2P is shorted to MIC2N which is grounded. If your design does not support the Acc_Det
feature, the Acc_Det pin must be left open (not connected).
