An implemented powerdown control port allows USB3_PHY to support four low-power states:
The USB3_PHY transitions from P0-active mode to low-power P1, or either of the two P2 states, is synchronized with USB1 transitions from U0 active state to U1, U2, and U3 low-power states through the input PIPE_POWERDOWN[1:0]. The PIPE port low-power behavior is configured from various bit fields inside the USB1.USB_GUSB3PIPECTL register. For more information on PIPE port low-power (LP) configuration, see USB Register Description in Section 24.7, SuperSpeed USB DRD.
