AN983B

PCI/miPCI Fast Ethernet Controller with integrated PHY

will be driven on with 20 Hz blinking frequency when a collision status is

detected in the half duplex configuration.

104

Led-100Lnk

(Led-speed)

4Leds mode: LED display for 100Mb/s speed. This pin will be driven on

continually when the 100Mb/s network operating speed is detected.

(3Leds mode): 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.

105

Led-Fd /Col

4Leds mode: 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 on with 20 Hz blinking frequency when a collision status is

detected in the half duplex configuration.

(3Leds mode): None

Vaux

When this pin is asserted, it indicates an auxiliary power source is supported

ACPI purpose, for detecting the auxiliary power source.

This pin should be or-wired connected to

1) 3.3V when 3.3Vaux support, or

2) 5V when 5Vaux support from 3-way switch.

Vcc-detect

When this pin is asserted, it indicates PCI power source is supported.

ACPI purpose, for detecting the main power is remained or not,

This pin should be connected to PCI bus power source +5V.

PMEP

This signal is used as the WOL pin. It provides a programmable positive or

negative pulse with approximately 50ms width.
