LED Display Information : Those signals indicate each port‘s Partition,
Jabber, Link/Activity, Utilization % (global), Collision % (global) in
sequence. For detail , see the LED timing specification
The Utilization % display define as following :
Group1 [ UU4 :UU0 ]
The Collision % display define as following :
Group0 [ C4 :C0 ]
Group1 [ CC4 :CC0 ]
LED status synchronous signal : The signal is a LED_CK period width signal
and repeated every 16 cycle. When high indicate the next cycle on the
LED[7:0] bus show the Partition status of port 8 to 0 respectively.
Collision LED Display : When Collision occur, the signal will
be “LOW” about 52.4 ms.
