Bits [31:28] Bits [27:20] Bits [19:8] Bits [7:0]
CAd = X Node ID = 0Ah Verb ID = 709h Payload = xxh
Bits Type Default Description
31 Read Only 0b
Presence Detect (PDET): A ‘1’ indicates that
there is “something” plugged into the jack associ-
ated with the Pin Widget. A ‘0’ indicates that
nothing is plugged in.
30:0 Read Only 0
Impedance Sense (IMPS): Not valid since the
widget is not capable of impedance sensing.
Bits Type Default Description
7:1 Write Only 0000000b Reserved
0 Write Only 0b
Right Channel (RCHAN): A write to this bit is
ignored since the widget is not capable of imped-
ance sensing.

2 Read Only 0b
L-R Swap: Not valid since the widget is not
capable of left/right swapping.

BTL: controls the output configuration of a Pin
Widget which has indicated support for balanced
I/O (bit 6, Pin Capabilities Parameter). When this
bit is 0, the output drivers are configured in nor-
mal, single-ended mode; when this bit is 1, they
are configured in balanced mode.
