Table 29.
Port Wake Capability (PORTWAKECAP) is a 2-byte register used to establish a policy
about which ports are for wake events; see
correspond to a physical port implemented on the current EHCI controller. Logic 1 in a bit
position indicates that a device connected below the port can be enabled as a wake-up
device and the port may be enabled for disconnect or connect, or overcurrent events as
wake-up events. This is an information only mask register. The bits in this register do not
affect the actual operation of the EHCI Host Controller. The system-specific policy can be
established by BIOS initializing this register to a system-specific value. The system
software uses the information in this register when enabling devices and ports for remote
wake-up.
Table 31.
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 of the register is given in
