Wake on Disconnect Enable(WKDSCNNT_E)
Writing this bit to a one enables the port to be sensitive to device
disconnects as wake-up events.
This field is zero if Port Power is zero.
The default value in this field is ‘0’.

Wake on Connect Enable(WKCNNT_E)
Writing this bit to a one enable the port to be sensitive to device connects
as wake-up events.
This field is zero if Port Power is zero.
The default value in this field is ‘0’.

Port Test Control
The value in this field specifies the test mode of the port. The encoding of
the test mode bits are as follow:

Port Owner
This bit unconditionally goes to a 0b when the Configured bit in the
CONFIGFLAG register makes a 0b to 1b transition. This bit unconditionally
goes to 1b whenever the Configured bit is zero.
System software uses this field to release ownership of the port to selected
host controller (in the event that the attached device is not a high-speed
device).Software writes a one to this bit when the attached device is not a
high-speed device. A one in this bit means that a companion host controller
owns and controls the port.
Default Value = 1b.
