RWE
RemoteWakeupEnable: This bit is used by the HCD to enable or
disable the remote wake-up feature upon the detection of
upstream resume signaling. When this bit is set and the
ResumeDetected bit in HcInterruptStatus is set, a remote wake-up
is signaled to the host system. Setting this bit has no impact on the
generation of hardware interrupt.
9RWC
RemoteWakeupConnected: This bit indicates whether the
HC supports remote wake-up signaling. If remote wake-up is
supported and used by the system, it is the responsibility of
system rmware to set this bit during POST. The HC clears the bit
upon a hardware reset but does not alter it upon a software reset.
Remote wake-up signaling of the host system is host-bus-specic
and is not described in this specication.
