PME_Support
This five-bit field indicates the power states in which the function may assert
PME#. A value of 0 for any bit indicates that the function is not capable of
asserting thePME# signal while in that power state.
bit27
PME# support D0
bit28
PME# support D1
bit29
PME# support D2
bit30
PME# support D3(hot)
bit31
PME# support D3(cold)
DM6588’s bit31~27=11000 indicates PME# can be asserted from D3(hot) &
D(cold).

RO
Reserved (DM6588 not supports D1, D2)
21
0
RO
A “1” indicates that the function requires a device specific initialization
sequence following transition to the D0 uninitialized state.
20
1
RO
Auxiliary Power Source
This bit is only meaningful if bit31 is a “1”.
This bit is “1” in DM6588 indicates that support for PME# in D3(cold)
requires auxiliary power.

0
RO
PME# Clock
“0” indicates that no PCI clock is required for the function to generate
PME#.

RO
Version
A value of 001 indicates that this function complies with the Revision 1.0 of
the PCI Power Management Interface Specification.
