Description
Collision LED.
Drives an LED to indicate that a collision
has occurred either locally or elsewhere in the stack.
Port 0 activity LED.
Drives an LED to indicate link/activity
on port 0. The LED is turned on when a link is established
and flashes off when a packet is being received.
Port 1 activity LED.
Drives an LED to indicate link/activity on
port 1. The LED is turned on when a link is established and
flashes off when a packet is being received.
Port 2 actlvlty LED.
Drives an LED to indicate link/activity on
port 2. The LED is turned on when a link is established and
flashes off when a packet is being received.
Port 3 activlty LED.
Drives an LED to indicate link/activity on
port 3. The LED is turned on when a link is established and
flashes off when a packet is being received.
Port 0 error LED.
Drives an LED to indicate an error on
port 0. See the text for a full description.
Port 1 error LED.
Drives an LED to indicate an error on
port 1. See the text for a full description.
Port 2 error LED.
Drives an LED to indicate an error on
port 2. See the text for a full description.
Port 3 error LED.
Drives an LED to indicate an error on
port 3. See the text for a full description.
Utilization LEDs.
Drives 5 LEDs to indicate utilization of the
network segment. See the text for a full description.

Description
25MHz reference clock.
Supplied from an external source
to all NWK954s on the local expansion bus.
Asynchronous reset. This signal is driven low by the on-
chip power-on reset circuit, but may also be driven low
externally for manual reset. Must be pulled high by an
external 5k
resistor.
Power-savlng enables.
11 enables power-saving on all
ports. 01 suppresses power saving on port 0, 10
suppresses power saving on port 3, 00 suppresses power-
saving on all ports.
Scrambler seed.
Each ot the four PHY modules in the
NWK954 is provided with a unique scrambler seed derived
from TA[4:2]. To ensure that all ot the local PHYs have
unique scrambler seeds, each NWK954 connected to the
local expansion bus should have its TA[4:2] input set to a
unique value by connecting to DIGVDD or DIGGND.
