WKOC Wake on over-current enable. Writing this bit to a one enables the port to be sensitive to over-current
WKDS Wake on disconnect enable. Writing this bit to a one enables the port to be sensitive to device disconnects as

0 Allow the port to identify itself as high speed.
1 Force the port to only connect at full speed.

0 Normal PHY operation.
1 Signal the PHY to enter low power suspend mode
Reading this bit indicates the status of the PHY.
Note: If there is no clock connected to the USBDR_CLK signals, PHCD must be set and the following
registers should not be written: DEVICE_ADDR/PERIODICLISTBASE, PORTSC, ENDPTCTRL0,
ENDPTCTRL1, ENDPTCTRL2.

This field is zero if Port Power (PP) is zero.
This bit is (OTG/host mode only) for use by an external power control circuit.

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.
• The PHY can be put into low power suspend—when the downstream device has been put into suspend
• The PHY can be put into low power suspend—when the device is not running (USBCMD[RS] = 0b) or
mode or when no downstream device is connected. Low power suspend is completely under the control of
software.
suspend signaling is detected on the USB. Low power suspend will be cleared automatically when the
resume signaling has been detected or when forcing port resume.
