Each serial output reports a specific status condition for all ports. Ports 0 through 7 are assigned
bits 0:7 in each stream (bits 3 and 4 are not used on the LXT9761).
Serial outputs report the following conditions for each port:
•
•

•
LEDS0 Serial Output indicates Activity.
0 = Active1 = Inactive
LEDS1 Serial Output indicates Polarity
0 = Switched Polarity1 = Normal Polarity
LEDS2 Serial Output indicates Duplex (D).
0 = Full Duplex1 = Half Duplex
LEDS3 Serial Output indicates Link.
0 = Link active1 = Link inactive
LEDS4 Serial Output indicates Collision.
0 = Collision active1 = Collision inactive
LEDS5 Serial Output indicates Receive.
0 = Receive active1 = Receive inactive
LEDS6 Serial Output indicates Transmit.
0 = Transmit active1 = Transmit inactive
LEDS7 Serial Output indicates Speed.
0 = 100 Mbps1 = 10 Mbps
