6.8.10 Configuration Default
The Configuration Default register is used by software as an aid in determining the configuration of jacks
and devices attached to the codec. At the time the codec is first powered on, this register is internally load-
ed with default values indicating the typical system use of this particular pin/jack. After this initial loading,
it is completely codec opaque, and its state, including any software writes into the register, must be pre-
served across reset events such as Link Reset or Codec Reset (the Function Reset Verb). Its state need
not be preserved across power level changes.

CAd = X Node ID = 09h Verb ID = 709h Payload = xxh
Bits Type Default Description
31 Read Only 0b
Presence Detect (PDET): A ‘1’ indicates that
something is plugged into the jack associated
with the Pin Widget. A ‘0’ indicates that nothing is
plugged in.
30:0 Read Only 0
Impedance Sense (IMPS): Not valid since the
widget is not capable of impedance sensing.
Bits Type Default Description
7:1 Write Only 0000000b Reserved
0 Write Only 0b
Right Channel (RCHAN): A write to this bit is
ignored since the widget is not capable of imped-
ance sensing.
