PI7C9X110 supports D0, D3-hot, D3-cold Power States. D1 and D2 states are not supported. The PCI Express
Physical Link Layer of the PI7C9X110 device supports the PCI Express Link Power Management with L0, L0s, L1,
L2/L3 ready and L3 Power States. For the PCI Port of PI7C9X110, it supports the standard PCI Power
Management States with B0, B1, B2 and B3.
During D3-hot state, the main power supplies of VDDP, VDDC, and VD33 can be turned off to save power while
keeping the VDDAUX, VDDCAUX, and VAUX with the auxiliary power supplies to maintain all necessary
information to be restored to the full power D0 state. PI7C9X110 has been designed to have sticky registers that are
powered by auxiliary power supplies. PME_L pin allows PCI devices to request power management state changes.
Along with the operating system and application software, PCI devices can achieve optimum power saving by using
PME_L in forward bridge mode. PI7C9X110 converts PME_L signal information to power management messages
to the upstream switches or root complex. In reverse bridge mode, PI7C9X110 converts the power management
event messages from PCIe devices to the PME_L signal and continues to request power management state change
to the host bridge.
PI7C9X110 also supports ASPM (Active State Power Management) to facilitate the link power saving.
PI7C9X110 supports Beacon generation but does not support WAKE# signal.
