Collision & FIFO Error LED Driver. This tri-state LED driver pin reports collisions and
FIFO errors. It pulses Low to report collisions, and pulses High to report FIFO errors. When

this pin is connected to the anode of one LED and to the cathode of a second LED, the
LXT915 will simultaneously monitor and report both conditions independently.
