Serial LEDs
The LXT98x3 provides a serial interface to support additional LED options. Standard shift
registers, either 74X595s (8-bit Serial-to-Parallel with Output Registers) or 74X164s (8-bit S/P
without registers) can be used to drive these additional LEDs. Collision10/100 and Activity10/100
status indications are provided on multiplexed configuration pins and duplicated on the serial port.
The LED serial interface consists of three outputs: clock (LEDCLK), parallel latch clock
(LEDLAT), and output data (LEDDAT). The parallel latch clock is used only with the 74X595
implementation. Refer to
Figure 14
for an illustration of the LED serial interface circuit.
Potentially, 30 LEDs can be driven by the LED serial interface via 4 S/P devices. The S/P serial
output is connected to the serial input of the first serial input device. To expand the chain, connect
the last serial output to serial input of next serial interface device.
Serial LED data is output in the anticipated priority order, from least likely to most likely to be
used:

This allows the user to leave off devices in the serial-to-parallel chain if the LEDs associated with
that condition aren

t desired. Refer to
Figure 6 on page 23
which illustrates the LED serial interface
port signalling and
Table 8 on page 23
which documents the Serial LED Stream.
