Description
LED[1][0]
Programs buffer allocation per port at reset time. Use the following table to select the
option.
Pulled low = 170 buffers (default).
Pulled high = adaptive mode.
LED[2][3]
Programs MAC address aging in the address look-up table at reset time. Aging
eliminates old entries from the table.
Pulled high = 5 minute aging (default).
Pulled low = disable.
LED[2][2]
Programs back pressure enable at reset time.
Pulled high = enable (default).
Pulled low = disable.
LED[2][1]
Programs aggressive back off in half-duplex at reset time.
Pulled high = enable (default).
Pulled low = disable.
LED[2][0]
Programs no excessive collision drop at reset time.
Pulled high = enable (default).
Pulled low = disable.
LED[3][3]
RESERVED.
Use external pulldown resistor if VDD_IO is 3.3V and LED[3][3] is being used. If
VDD_IO is not 3.3V or this LED is not used, then no pull-down is required ( floating).
LED[3][2:0]
Programs force 100BaseTX mode at reset time. Use the table below to set this mode
on the appropriate port. Assuming the corresponding port auto-negotiation is disabled.
