PLED2n/MDA2n
PLED1n/MDA1n
Management Interface (MI)/LED Signals
When programmed as a 100 Mbits/s Link Detect Output
(default):
Pin
HIGH
LOW
During powerup or reset, this pin is high-impedance and
the level on this pin is latched in as the physical device
address MDA3n for the MI serial port.
Programmable LED Output/MI Address Bit
The default function of this pin is to be an Activity Detect
output. This pin can also be programmed through the MI
serial port to indicate other events or be user controlled.
This pin can drive an LED from V
When programmed as an Activity Detect Output (default):
Pin
HIGH No Activity
LOW
During powerup or reset, this pin is high-impedance and
the level on this pin is latched in as the physical device
address MDA2n for the MI serial port.
Programmable LED Output/MI Address Bit
The default function of this pin is to be a Full Duplex
Detect output. This pin can also be programmed through
the MI serial port to indicate other events or be user
controlled. This pin can drive an LED from both V
GND.
When programmed as Full Duplex Detect Output
(default):
Pin
HIGH
LOW
