14 LED Interface
The PHY has five dedicated LED[4:0] pins to drive 5 LEDs directly. For power savings, all LED outputs can be configured to
pulse at 5kHz with a 20% duty cycle. All LED outputs are active-low and driven with 3.3V from the VDD33A power supply when
deasserted.
Due to the fact that the 100BASE-FX mode uses 100BASE-T resources, its indications are those of the 100BASE-T mode.
Four different functions have been assigned to each LED pin. Selection is done using either the CMODE hardware configuration
(see
page 117. The functions are assigned according to the following table:
LED functions are summarized in the following table.
