7 / 66 page 7/66 STE10/100 LED display & Miscellaneous 90 LED M1- LK/Act or LED M2- Act O 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. 92 LED M1- Speed or LED M2- 100 Link O 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. 91 LED M1- Fd/Col or LED M2- 10 Link O 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. 89 Vaux- detect I When this pin is asserted, it indicates an auxiliary power source is supported from the system. 88 Vcc-detect I When this pin is asserted, it indicates a PCI power source is supported.
