Data Sheet
Single Color LED Display (cont’d)
Status
These 3 pins have power on reset values on them. Samurai-6M/6MX (ADM6996M/MX)
needs to consider these values to drive the correct value. If the power on reset value is
value_power_on, then the display is as follows:
1. First period: This period lasts 1.28 s for LED on test. Samurai-6M/6MX
2. Second period: This period lasts 0.48 s for LED off test. Samurai-6M/6MX
3. Normal Period: This period indicates the duplex/collision status.
~value_power_on = Port links up in the full-duplex mode. LED is ON.
value_power_on = Port links down. LED flashes at 10 Hz.
0/1
If
~value_power_on = Port links up in the duplex mode. LED is ON.
value_power_on = Port links down or links up in the half-duplex mode. LED is OFF.
0/1
If
DUPCOL0: 10m collision indicator.
0/1
value_power_on = When the above event is not satisfied, the LED is OFF.
DUPCOL1: 100 m collision indicator.
0/1
value_power_on = The above event is not satisfied. LED is OFF.
The behavior of these pins is the same as the LNKACT, except the normal period.
Normal period: This period indicates the duplex/collision status.
~value_power_on = Port links up in the full-duplex mode. LED is ON.
value_power_on = Port links down. LED is OFF.
0/1
If
~value_power_on = Port links up in the duplex mode. LED is ON.
value_power_on = Port links down or links up in the half-duplex mode. LED is OFF.

The LED flashes at 20 Hz.
One of the ports links up in 10M half-duplex mode and detects a collision event. The
Port links up and collision is detected. The LED flashes at 10 Hz.
This value is cancelled. LED doesn’t blink.
