LED Functions
The LXT972M Transceiver has these direct LED driver pins: LED/CFG1, LED/CFG2, and LED/
CFG3.
On power-up, all the drivers are asserted for approximately 1 second after reset de-asserts. Each
LED driver can be programmed using the LED Configuration Register (
Table 54, “LED
Configuration Register - Address 20, Hex 14” on page 87
) to indicate one of the following
conditions:
Collision Condition
Duplex Mode
Link Status
Operating Speed
Receive Activity
Transmit Activity
The LED drivers can also be programmed to display various combined status conditions. For
example, setting Register bits 20.15:12 to ‘1101’ produces the following combination of Link and
Activity indications:
If Link is down, LED is off. If activity is detected from the MAC, the LED still blinks even if
the link is down.
If Link is up, LED is on.
If Link is up and activity is detected, the LED blinks at the stretch interval selected by Register
bits 20.3:2 and continues to blink as long as activity is present.
For the LXT972M Transceiver, the LED driver pins also provide initial configuration settings. The
LED pins are sensitive to polarity and automatically pull up or pull down to configure for either
open drain or open collector circuits (10 mA Max current rating) as required by the hardware
configuration. For details, see the discussion of
“Hardware Configuration Settings” on page 33
.
