PLED0n/MDA0n
PLED5n
PLED4n
Signal Descriptions
During powerup or reset, this pin is high-impedance and
the level on this pin is latched in as the physical address
device address MDA1n for the MI serial port.
Programmable LED Output/MI Address Bit
The default function of this pin is to be a 10 Mbits/s Link
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
When programmed as 10 Mbits/s Link Detect Output
(default):
Pin
HIGH
LOW
During powerup or reset, this pin is high-impedance and
the value on this pin is latched in as the address MDA0n
for the MI serial port.
Receive LED Output
The function of this pin is to be a Receive Activity Detect
output. This pin can also drive an LED from V
HIGH = No Receive Activity
LOW = Receive packet occurred: hold LOW for 100 ms
Transmit LED Output
The function of this pin is to be a Transmit Activity Detect
output. This pin can also drive an LED from V
HIGH = No Transmit Activity
LOW = Transmit packet occurred: hold LOW for 100 ms
