From one side the control over power up/down states of the USB3_PHY is provided through a Power control modules tightly integrated with the the PCIe1_PHY and PCIe2_PHY physical layer TX/RX components. On the other side, the PCIe_PHY PIPE i/f logic of the PCIe_PHY wrapper conveys power transition commands/states (L0–L3) from the PCIe_SS1 and PCIe_SS2 MAC PIPE power management-ports to the PCIe1_PHY and PCIe2_PHY components as their corresponding P0 (active) and P0s, P1, P2 (low-power) states.
