Description
Indicates the type of physical interface on Port-G:
0h = Unknown
1h = 3.5mm stereo/mono jack
2h = ¼” stereo/mono jack
3h = ATAPI internal
4h = RCA jack (for analogue audio or coaxial S/PDIF)
5h = Optical
6h = Other digital
7h = Other analogue
8h = Multi-channel analogue (DIN)
9h = XLR/Professional
Ah = RJ-11 (modem)
Bh = Combination
Ch-Eh = Reserved
Fh = Other
Indicates the colour of the physical jack on Port-G:
0h = Unknown
1h = Black
2h = Grey
3h = Blue
4h = Green
5h = Red
6h = Orange
7h = Yellow
8h = Purple
9h = Pink
Ah-Dh = Reserved
Eh = White
Fh = Other
Presence detection override:
Pre-Production
0 = Presence detection indicated by Pin Capabilities Parameter
1 = Presence detection not supported. If the Pin Capabilities Parameter
indicates that that presence detection is supported by the node, then this
bit is used to override it to indicate the external circuitry is not capable of
supporting presence detect

All other values are reserved
RW
2h
Association number:
0h = Reserved
1h-Eh = Multi Channel or Single Pin Widget
Fh = Single Pin Widget Only
RW
1h
Sequence number used to define individual channel pairs within a stream.
All values (0h-Fh) are available for use. Use a value of 0h for Single Pin
Widget.
Note: The Configuration Default Verb is not reset to its default value during a reset from any source. The settings are only lost
when digital power is removed from the WM8850. When digital power is restored, the System BIOS must restore the settings.
