D2_SPT
D2 Support. If this bit is a 1, this
function supports the D2 Power
Management State.
This bit is read only.
9
D1_SPT
D1 Support. If this bit is a 1, this
function supports the D1 Power
Management State.
This bit is read only.
8-6
AUX_CURRENT
Auxiliary Current Requirements.
This 3-bit field reports the
3.3Vaux current requirements for
the PCI function. If the Data Reg-
ister has been implemented by
this function, then reads of this
field must return a value of 000b
and the Data Register will take
precedence over this field for
3.3Vaux current requirement re-
porting.
If PME generation from D3
cold
is
not supported by the function
(PMC (15) = 0), this field must re-
turn a value of 000b when read.
For functions that support PME
from D3
cold
and do not implement
the Data Register, the following
bit assignments apply:
These bits are read only.

When this bit is 1, it indicates that
special initialization of the func-
tion is required (beyond the stan-
dard PCI configuration header)

before the generic class device
driver is able to use it.
This bit is read only.
4
RES
Reserved location.
3
PME_CLK
PME Clock. When this bit is a 1,
it indicates that the function relies
on the presence of the PCI clock
for PME operation. When this bit
is a 0 it indicates that no PCI
clock is required for the function
to generate PME.
Functions that do not support
PME generation in any state
must return 0 for this field.
This bit is read only.
2-0
PMIS_VER Power Management Interface
Specification Version. A value of
001b indicates that this function
complies with revision 1.0 of the
PCI Power Management Inter-
face Specification.

PME_STATUS PME Status. This bit is set when
the function would normally as-
sert the PME signal independent
of the state of the PME_EN bit.
Writing a 1 to this bit will clear it
and cause the function to stop as-
serting a PME (if enabled). Writ-
ing a 0 has no effect.
If the function supports PME from
D3
cold
, then this bit is sticky and
must be explicitly cleared by the
operating system each time the
operating system is initially load-
ed.
This bit is always read/write ac-
cessible. Sticky bit. This bit is re-
set
by
POR.
S_RESET, or setting the STOP
bit has no effect.
