This Power Management section applies for all AC’97 controller functions. After a power
management event is detected, the AC’97 controller will wake the host system. The
sections below describe these events and the AC’97 controller power states.
Device Power States
The AC’97 controller supports D0 and D3 PCI Power Management states. Notes

1. The AC’97 controller hardware does not inherently consume any more power when
2. In the D0 state, all implemented AC’97 controller features are enabled.
3. In D3 state, accesses to the AC’97 controller memory-mapped or I/O range will
