H-Phone Enable (HPE): Not supported on this
widget.
Output Enable (OUTE): Not supported on this
widget. Used by WHQL test to set VREFE = HiZ
mode.
Input Enable (INE): This bit has no affect on the
input path. Per HD Audio Spec., when ‘1’, this bit
enables the input path of the Pin Widget. When
set to ‘0’, the input path of the Pin Widget will
continue to operate.
Reserved
VREF Enable (VREFE): This field selects one of
the possible states for the VREF signal(s). The
pin associated with this function is MICBIAS.
If the value written to this control does not corre-
spond to a supported value (‘000’b, ‘001’b,
‘010’b or ‘100’b), the VREFE bits must retain the
previous value.
‘000’b = Hi-Z
‘001’b = 0.5*VA
‘010’b = GND
‘100’b = 0.8*VA
