OFFSET R/W
44H
R
Capability ID :
The value is 01H to indicate power management block.
45H
R
Next item pointer :
The value is 00H to indicate this is the last block
46H
R
Power management capabilities, :
The value is 21H to indicate version 1.0 of PCI power management specification and need a device specific initialization
sequence following transition to the DO uninitialized state
47H
R
Power management capabilities :
The value is 48H to indicate PME# support from Do and D3 hot state.
48-49H
R/W Power management status :
<15>
: PME# status --
Set when the function would normally assert the PME# signal independent of the state of the PME# pin enable
bit. Write a “1” to this bit will clear it and cause the function to stop asserting a PME# (if enabled). Write a “0” no
effect. When reset default is “0”.
<8> : PME# pin enable control bit --
A “1” enable the function to assert PME#. Writing a “0” PME# assertion is disabled. When reset default is “0”
<1:0> : Power state --
Only 00 (D0) and 11 (D3) supported
