DATASHEET
1.1.6 Power Management
The LAN9512/LAN9512i features three variations of USB suspend: SUSPEND0, SUSPEND1, and
SUSPEND2. These modes allow the application to select the ideal balance of remote wakeup
functionality and power consumption.
SUSPEND0: Supports GPIO, “Wake On LAN”, and “Magic Packet” remote wakeup events. This
suspend state reduces power by stopping the clocks of the MAC and other internal modules.
SUSPEND1: Supports GPIO and “Link Status Change” for remote wakeup events. This suspend
state consumes less power than SUSPEND0.
SUSPEND2: Supports only GPIO assertion for a remote wakeup event. This is the default suspend
mode for the LAN9512/LAN9512i.
