An implemented powerdown control port allows PCIe_PHY to support four low-power states:
The PCIe PHY power transitions are managed from connected PCIe_SS controller power management state machines according to desired Link and physical layer power states via signal PIPE_POWERDOWN[1:0]. For more information see Section 24.9.4.5 PCIe Controller Power Management in Section 24.9 PCIe Controllers chapter.
