EHCI Host Controller. The system-specific policy can be established by BIOS
initializing this register to a system-specific value. System software uses the
information in this register when enabling devices and ports for remote wake-up.

Power management registers
Cap_ID register (address: value read from address 34H + 0H):
The Capability
Identifier (Cap_ID) register, when read by the system software as 01H indicates that
the data structure currently being pointed to is the PCI Power Management data
structure. Each function of a PCI device may have only one item in its capability list
with Cap_ID set to 01H. The bit description o the register is given in
Table 31
.
Next_Item_Ptr register (address: value read from address 34H + 1H):
The Next
Item Pointer (Next_Item_Ptr) register (see
Table 32
) describes the location of the next
item in the function’s capability list. The value given is an offset into the function’s PCI
Configuration Space. If the function does not implement any other capabilities
defined by the PCI-SIG for inclusion in the capabilities list, or if power management is
the last item in the list, then this register must be set to 00H.
PMC register (address: value read from address 34H
+
2H):
The Power
Management Capabilities (PMC) register is a two-byte register, and the bit allocation
is given in
Table 33
. This read-only register provides information on the capabilities of
the function related to power management.
