1. R/W = Read /Write. RO = Read Only. LH = Latching High
2. Link status is the primary LED driver. The LED is asserted (solid ON) when the link is up.
The secondary LED driver (Receive or Activity) causes the LED to change state (blink).
Activity causes the LED to blink, regardless of the link status.
3. Combined event LED settings are not affected by Pulse Stretch Register bit 20.1. These display settings
are stretched regardless of the value of 20.1.
4. Duplex status is the primary LED driver. The LED is asserted (solid ON) when the link is full-duplex.
Collision status is the secondary LED driver. The LED changes state (blinks) when a collision occurs.
5. Values are approximations. Not guaranteed or production tested.
