Preliminary Data Sheet
I/O
Description
B,Z Inter-LEMRIC Data:
When asserted as an output this signal provides a serial data
stream in NRZ format.
This signal is asserted by a LEMRIC when it is receiving data
from one of its network segments. The default condition of this
signal is to be an input. In this state, it may be driven by other
devices on the Inter-LEMRIC bus.
B,Z Inter-LEMRIC Enable:
When asserted as an output this signal provides an activity-framing
enable for the serial data stream. The signal is asserted by a
LEMRIC when it is receiving data from one of its network segments.
The default condition of this signal is to be an input. In this state it
may be driven by other devices on the inter-LEMRIC bus.
B,Z Inter-LEMRIC Clock:
When asserted as an output this signal provides a clock signal for
the serial data stream. Data (XIRD) is changed on the falling edge of
the clock. The default condition of this signal is to be an input. When
an input, XIRD is sampled on the rising edge of the clock. In this
state it may be driven by other devices on the Inter-LEMRIC bus.
B,Z Collision on Port N:
This denotes that a collision is occurring on the port receiving the
data packet (Port N). The default condition of this signal is to be
an input. In this state it may be driven by the other devices on the
Inter-LEMRIC bus.
B,Z Activity on Port N:
This is a bi-directional signal. The LEMRIC asserts this signal
when data or collision information is received from one of its
network segments. The LEMRIC senses this signal when this or
another LEMRIC in a multi-LEMRIC system is receiving data or
collision information.
B,Z Activity on ANY Port Excluding Port N:
This is a bi-directional signal. The LEMRIC asserts this signal
when a transmit collision is experienced or multiple ports have
active collisions on their network segments.
The LEMRIC senses this signal when this LEMRIC or other LEMRICs
in a multi-LEMRIC system are experiencing transmission collision or
multiple ports have active collisions on their network segments.

I/O
Description
O Global Collision LED (Active-Low):
This CMOS output indicates the status of the LEMRIC's any
collision activity.
O Global Jabber LED (Active-Low):
This CMOS output indicates when the LEMRIC's watchdog timer
begins to jab and stays active until end of the unjab wait period.
