H-Phone Enable (HPE): Set to ‘0’ since there is
no low impedance amplifier associated with this
pin widget.
6 Read/Write 0b
Output Enable (OUTE): This bit has no effect on
the output path. Per HD Audio spec, a ‘1’
enables the output path of the Pin Widget. When
‘0’, the output path of the Pin Widget is shut off.
5 Read Only 0b
Input Enable (INE): Set to ‘0’ since there is no
input path associated with the pin widget.
4:3 Read Only 00b Reserved
2:0 Read Only 000b
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.
