6.12.5 Digital Mic In 1 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.
