6.9.11 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.

Connection Type (CTYP): Indicates the type of
physical connection is an 1/8” jack.
Color (COL): This field indicates the color of the
4h
physical jack for use by software. The color
selected is green.

Miscellaneous (MISC): No PDC override.
Default Association (DA): This field is used by
software to group Pin Complex (and therefore
jacks) together into functional blocks to support
Fh
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.
0h
Sequence (SEQ): This field indicates the order
of the jacks in the association group.
