1. R/W = Read /Write.
2. Link status is the primary LED driver. The LED is asserted (solid ON) when the link is up.
3. Combined event LED settings are not affected by Pulse Stretch bit 20.1. These display settings are stretched regardless of
4. Duplex status is the primary LED driver. The LED is asserted (solid ON) when the link is full duplex.
5. Duplex LED maybe active for a brief time after loss of link.
Bit
The secondary LED driver (Receive, Activity or Isolate) causes the LED to change state (blink).
the value of 20.1.
Collision status is the secondary LED driver. The LED changes state (blinks) when a collision occurs.
