Description
Output (after reset)
Mode 0: Collision (on = collision/off = no collision)
Mode 1: Transmit Activity (on during transmission)
Mode 2: Link activity (10Mb mode)
Mode 3: Full Duplex + Collision
(constant on = full duplex; intermittent on = collision; off = half-duplex with no
collision)
Output (after reset)
Mode 0: Link + Activity
When LED is solid “on”, it indicates the link is on for both 10 or 100BaseTX,
but no data is transmitting or receiving.
When LED is solid “off”, it indicates the link is off.
When LED is blinking, it indicates data is transmitting or receiving for either 10
or 100 BaseTX
Mode 1: Receive Activity (on = receiving/off = not receiving)
Mode 2: Link activity (100Mb mode)
Mode 3: Link + Activity (see description above)
Note: Mode is set by MODESEL[3:0] ; please see description in UP
