Description
Reserved
H-Phone Enable (HPE): Not supported.
Output Enable (OUTE): This bit has no affect on
the output path. Per HD Audio Spec., when ‘1’,
this bit enables the output path of the Pin Widget.
When ‘0’, the output path is shut off.
Input Enable (INE): Set to ‘0’ since there is no
input path associated with the pin widget.
Reserved
VREF Enable (VREFE): The Pin Widget does
not support VREF generation as indicated in the
Pin Capabilities. As such, this field should always
be “000b” to select the Hi-Z state.
