This field is zero if Port Power(PP) is zero or in device mode.
This bit is (OTG/host mode only) for use by an external power control circuit.
Port test control. Any other value than zero indicates that the port is operating in test mode.

Refer to the USB Specification Revision 2.0 [3] for a description on how these bits are to be used.
This field is output from the module on the USB port control signals for use by an external LED driving circuit.
Port owner. Unconditionally goes to a 0 when the configured bit in the CONFIGFLAG register makes a 0 to 1
transition. This bit unconditionally goes to 1 whenever the Configured bit is zero. System software uses this
field to release ownership of the port to a selected the module (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 an internal companion controller owns and controls the port.
Port owner hand-off is not implemented in this design, therefore this bit is always 0.
Port power. Represents the current setting of the switch (0=off, 1=on). When power is not available on a port
(that is, PP equals a 0), the port is non-functional and will not report attaches, detaches, etc.
When an over-current condition is detected on a powered port, the PP bit in each affected port is transitioned
by the host controller driver from a one to a zero (removing power from the port).
This feature is implemented in the host/OTG controller (PPC = 1).
In a device-only implementation port power control is not necessary, thus PPC and PP = 0.
Line status. Reflect the current logical levels of the USB D+ (bit 11) and D– (bit 10) signal lines. The use of line
status by the host controller driver is not necessary (unlike EHCI), because the connection of FS and LS is
managed by hardware.
