Signal Descriptions
LEDSEL[1:0] LED Select
Output
These pins indicate which port’s status is being output on
COLLOUTN, LBADN, LPASSN, RCVNGN, and
TRNSMTN in the current cycle.
LPASSN
Link Test Status
This pin is the Link Test Status of one of the four ports (a
multiplexer selects which port’s LPASSN signal is output).
The L64381 asserts LPASSN when the Link test passes.
LPASSN combined with external logic can drive an LED,
allowing the status of LPASSN to be viewed.
LEDSEL[1:0] indicate which port is selected.
Output
RCVNGN
Receiver Status
This pin is the Receiver Status from one of the four ports
(a multiplexer selects which port’s RCVNGN signal is out-
put). The L64381 asserts RCVNGN when the port is
receiving data on the Network Interface. RCVNGN com-
bined with external logic can drive an LED, allowing the
status of RCVNGN to be viewed. LEDSEL[1:0] indicate
which port is selected.
Output
TRNSMTN
Transmitter Status
This pin is the Transmitter Status from one of the four
ports (a multiplexer selects which port’s TRNSMTN signal
is output). It is asserted when the port is transmitting data
on the Network Interface. TRNSMTN combined with
external logic can drive an LED, allowing the status of
TRNSMTN to be viewed. LEDSEL[1:0] indicate which
port is selected.
