The PCI_PMC structure is used to report the contents of the power management capabilities register.
Contains a 3-bit integer that indicates the version of the PCI Power Management Interface Specification that the device complies with. For a list of values that can be assigned to this member, see the PCI Local Bus Specification.
Indicates, when 1, that the device relies on the presence of the PCI clock for operation of the PME signal. When this member is a "0", no PCI clock is required to generate the PME signal.
Reserved.
Indicates when 1 that the device requires a special initialization. For more information about this value, see the PCI Local Bus Specification.

Indicates that the device can assert the PME signal from D0.
Indicates that the device can assert the PME signal from D1.
Indicates that the device can assert the PME signal from D2.
Indicates that the device can assert the PME signal from D3.
Indicates that the device can assert the PME signal from D3.
The _PM_SUPPORT structure.
The power management capabilities register, whose contents are reported in the PCI_PMC structure, provides information about the power management capabilities of the device.
