LAN950x

Broadcast Frame Received, and “Good Frame” Received, wake events, as well as provision for an additional wakeup

event to signal PHY Link Up via GPIO7, is reflected in the LAN9500A/LAN9500Ai detection logic. The following sections

illustrate and discuss the detection logic for all of the devices in theLAN950x family.

5.12.1.1

LAN9500/LAN9500i Wake Detection Logic

A simplified diagram of the wake event detection logic for LAN9500/LAN9500i is shown in Figure 5-30.
