Description

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.

Impedance Sense (IMPS): Not valid since the

widget is not capable of impedance sensing.

Default

0000000b

0b

Description

Reserved

Right Channel (RCHAN): A write to this bit is

ignored since the widget is not capable of imped-

ance sensing.

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.
