Description

LEDA_LINK_UP_N

TTL12

LED 0 – Link Up LED

This corresponds to port 0’s LED#0 from the

631xESB/632xESB.

LEDA_ACTIVITY_N

TTL12

LED 1 – 10 Mbps LED

This corresponds to port 0’s LED#1 from the

631xESB/632xESB.

LEDA_SPEED_100_N

TTL12

LED 2 – 100 Mbps LED

This corresponds to port 0’s LED#2 from the

631xESB/632xESB.

LEDA_SPEED_1000_N

TTL12

LED 3 – 1000 Mbps LED

This corresponds to port 0’s LED#3 from the

631xESB/632xESB.

LEDA_DUPLEX

TTL12

LED 4 – Full Duplex LED

This LED will light when port 0’s PHY is operating in

Full Duplex Mode

LEDA_TX_ACTIVITY

TTL12

LED 5 – Transmit Activity LED

This LED will light when the port 0’s PHY transmits a

packet

LEDA_RX_ACTIVITY

TTL12

LED 6 – Receive Activity LED

This LED will light when the port 0’s PHY receives a

packet

This pin also functions as the clock view pin and will

output clock signals required for IEEE conformance

testing. This pin should have a stuffing option for a test

header.
