4.3Power Management
The LAN9311/LAN9311i Port 1 and Port 2 PHYs and the Host MAC support several power management and wakeup features.
The LAN9311/LAN9311i can be programmed to issue an external wake signal (PME) via several methods, including wake on LAN, wake on link status change (energy detect), and magic packet wakeup. The PME signal is ideal for triggering system
The PME module handles the latching of the Port 1 & 2 PHY
The PME output characteristics can be configured via the PME_TYPE, PME_IND, and PME_POL bits of the Power Management Control Register (PMT_CTRL). These bits allow the PME to be
