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.

Read/Write

00b

Port Connectivity (PCON): The port complex is

connected to a jack.

29:24

Read/Write

000001b

Location (LOC): This field indicates the physical

location of the jack or device to which the pin

complex is connected. Set to External | Rear.

23:20

Read/Write

Default Device (DD): Indicates the intended use

of the connection is for Line Out.

19:16

Read/Write

Connection Type (CTYP): Indicates the type of

physical connection is 1/8” jack.

15:12

Read/Write

Color (COL): This field indicates the color of the

physical jack for use by software. The color

selected is Green.

11:8

Read/Write

Miscellaneous (MISC): No PDC override.

7:4

Read/Write

Default Association (DA): This field is used by

software to group Pin Complex (and therefore

jacks) together into functional blocks to support

multichannel operation. All jacks with the same

association number may be assumed to be

grouped together. A value of all ‘0’s is reserved.

A value of all ‘1’s in this field indicates that the

Association has the lowest priority.

3:0

Read/Write

Sequence (SEQ): This field indicates the order

of the jacks in the association group.
