% (global), Collision % (global) in sequence. For detail , see the LED timing
specification
/LUTI[2:0] : When MODE=” 0” , Those pins drive utilization[2:0] LEDs
directly.
The Utilization % display define as following : (See Note 1 also)
The Collision % display define as following :
LED clock signal : When MODE=” 1” , The signal is a discontinue clock for
LED signals serial shift out. The clock period width is 40nS and last 16 cycle
with every 125ms repeated.
/LUTI[3] : When MODE=” 0” , This pin drive utilization[3] LED directly.
Collision LED for 10Mbps : When MODE=” 1” , This pin indicates 10Mbps
repeater collision occurred.
/LUTI[4] : When MODE=” 0” , This pin drive utilization[4] LED directly.
NC : When MODE=” 1” , The pin function is reserved.
/LUTI[5] : When MODE=” 0” , This pin drive utilization[5] LED directly.
Collision LED for 100Mbps : This pin indicates 100Mbps repeater collision
occurred.
