Description
This pin can be programmed as mode 1 or mode 2:
For mode 1:
LED display for Link and Activity status. This pin will be driven on continually
when a good Link test is detected. This pin will be driven at a 10 Hz blinking
frequency when either effective receiving or transmitting is detected.
For mode 2:
LED display for Activity status. This pin will be driven at a 10 Hz blinking
frequency when either effective receiving or transmitting is detected.
This pin can be programmed as mode 1 or mode 2:
For mode 1:
LED display for 100M b/s or 10M b/s speed. This pin will be driven on continually
when the 100M b/s network operating speed is detected.
For mode 2:
LED display for 100Ms/s link status. This pin will be driven on continually when
100Mb/s network operating spped is detected.
This pin can be programmed as mode 1 or mode 2:
For mode 1:
LED display for Full Duplex or Collision status. This pin will be driven on
continually when a full duplex configuration is detected. This pin will be driven at
a 20 Hz blinking frequency when a collision status is detected in the half duplex
configuration.
For mode 2:
LED display for 10Ms/s link status. This pin will be driven on continually when
10Mb/s network operating speed is detected.
When this pin is asserted, it indicates an auxiliary power source is supported
from the system.
When this pin is asserted, it indicates a PCI power source is supported.
