Mode 1: (LED_SEL_MODE = 1): This mode is used with standard TTL (74LS599) or
HCMOS (74HC599) octal shift registers with latches, providing the most general and cost-
effective implementation of the serial data stream conversion.
In addition to these physical modes of operation, there are two types of specific LED data
decodes available for fiber and copper modes. This option is a global selection and controls
the operation of all ports (see
LED Interface Signal Description
The IXF1104 MAC LED interface consists of three output signal signals that are 2.5 V
CMOS level pads.
LED Interface Signal Descriptions
Mode 0: Detailed Operation
Please refer to the SGS Thompson* M5450 datasheet for device-operation information.
The operation of the LED Interface in Mode 0 is based on a 36-bit counter loop. The data for
each LED is placed in turn on the serial data line and clocked out by the LED_CLK.

the falling edge of the clock and is valid for almost the entire clock cycle. This ensures that
the data is valid during the rising edge of the LED_CLK, which clocks the data into the
M5450 device.

Pin Description
This signal is an output that provides a continuous clock synchronous to the
serial data stream output on the LED_DATA pin. This clock has a maximum
speed of 720 Hz.
The behavior of this signal remains constant in all modes of operation.
This signal provides the data, in various formats, as a serial bit stream. The data
must be valid on the rising edge of the LED_CLK signal.
In Mode 0, the data presented on this pin is TRUE (Logic 1 = High).
In Mode 1, the data presented on this pin is INVERTED (Logic 1 = Low).
This is an output pin, and the signal is used only in Mode 1 as the Latch enable
for the shift register chain.
This signal is not used in Mode 0, and should be left unconnected.
