Port speed

Low-speed
Serial/ 1.1 PHY (Full-speed only)
Wake on disconnect enable (WKDSCNNT_E)
This bit is 0 if PP (Port Power bit) is 0.
Disables the port to wake up on device disconnects.
Writing this bit to a one enables the port to be sensitive to device
disconnects as wake-up events.
Wake on over-current enable (WKOC_E)
Disables the port to wake up on over-current events.
Writing a one to this bit enabled the port to be sensitive to over-current
conditions as wake-up events.
In host mode, the PHY can be put into Low Power Suspend – Clock
Disable when the downstream device has been put into suspend mode or
when no downstream device is connected. Low power suspend is
completely under the control of software.
Writing a 0 enables the PHY clock. Reading a 0 indicates the status of the
PHY clock (enabled).
Writing a 1 disables the PHY clock. Reading a 1 indicates the status of the
PHY clock (disabled).
Port connects at any speed.
Writing this bit to a 1 will force the port to only connect at Full Speed. It
disables the chirp sequence that allows the port to identify itself as High
Speed. This is useful for testing FS configurations with a HS host, hub or
device.
This register field indicates the speed at which the port is operating. For HS
mode operation in the host controller and HS/FS operation in the device
controller the port routing steers data to the Protocol engine. For FS and
LS mode operation in the host controller, the port routing steers data to the
Protocol Engine w/ Embedded Transaction Translator.
