RO
PME_Support
These five bits field indicate 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
the PME# signal while in that power state.
bit27
Æ PME# support D0
bit28
Æ PME# support D1
bit29
Æ PME# support D2
bit30
Æ PME# support D3(hot)
bit31
Æ PME# support D3(cold)
DM9102A’s bit31~27=11000 indicates PME# can be asserted fromD3(hot) &
D3(cold).
26:22
00000
RO
Reserved (DM9102A not supports D1, D2)
21
1
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 DM9102A indicates that support for PME# in D3(cold) requires
auxiliary power.
19
0
RO
PME# Clock
“0” indicates that no PCI clock is required for the function to generate PME#.
18:16
001
RO
Version
A value of 001 indicates that this function complies with the Revision 1.0 of the PCI
Power Management Interface Specification.
A value of 010 is for DM9102A/A that complies with the revision 1.1 of the PCI
Power Management Interface Specification.
15:8

RO
Next Item Pointer
The offset into the function’s PCI Configuration Space pointing to the location of
next item in the function’s capability list is “00h”
7:0
01h
RO
Capability Identifier
When “01h” indicates the linked list item as being the PCI Power Management
Registers.
