LED Configuration

The 82575EB provides 4 LEDs per port that may be used to indicate the status of the traffic. The

default setup of the LEDs is done via the EEPROM words 1Ch and 1Fh. The default setup for both ports

is the same. This setup is reflected in the LEDCTL register of each port. Each driver may change its

setup individually. For each of the LEDs the following parameters can be defined:

1. Mode: Defines which information is reflected by this LED. The encoding is described in the LEDCTL

2. Polarity: Defines the polarity of the LED.

3. Blink mode: should the LED blink or be stable.

In addition, the blink rate of all LEDs can be defined. The possible rates are 200 ms or 83 ms for each

phase. There is one rate for all LEDs
