MODE
Note 4.1
The LAN9117 10/100 PHY CRS signal operates in two modes: Active and Low. When in
Active mode, CRS will transition high and low upon line activity, where a high value
indicates a carrier has been detected. In Low mode, CRS stays low and does not indicate
carrier detection. The CRS signal cannot be used as a verification method of transmitted
packets when transmitting in 10 or 100 Mbps in full-duplex mode.
