Description

Reserved

L-R Swap: Not valid since the widget is not

capable of left/right swapping.

EAPD: Not supported on this widget.

BTL: controls the input configuration of a Pin

Widget which has indicated support for balanced

I/O (bit 6, Pin Capabilities Parameter). When this

bit is 0, the inputs are configured in single-ended

or pseudo-differential mode; when this bit is 1,

they are configured in balanced (fully differential)

mode.

Note: This bit is ORâed with the ADC2 Gain bit in

the ADC Configuration (CIR = 0002h) Regis-

ter of the Vendor Processing Widget (Node

ID = 11h).

6.11.12 Line In 1/Mic In 2 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.
