Output After Reset = Used for Group B LEDs.
RTL8306SD/RTL8306SDM controlling LED:
LEDMode[1:0]=11 -> Speed (On=100, Off=10)
LEDMode[1:0]=10 -> Speed (On=100, Off=10)
LEDMode[1:0]=01 -> Speed (On=100, Off=10)
LEDMode[1:0]=00 -> Speed (0n=100, Off=10)
CPU Controlled LED.
For Single-color LED:
On=Corresponding register 1
Off=Corresponding register 0
For Bi-color LED:
Displays also depend on pin LED_ADD status.
Input Upon Reset = Refer to Table 9, on page 27, and Table 10, on
page 29.

Output After Reset = Used for Group C LEDs.
RTL8306SD/RTL8306SDM controlling LED:
LEDMode[1:0]=11 -> Link/Act: (On=Link, Off=No Link, Flash=Tx or
Rx activity)
LEDMode[1:0]=10 -> Act: (Off=No activity, Flash=Tx or Rx activity)
LEDMode[1:0]=01 -> RxAct: (Off=No activity, Flash=Rx activity)
LEDMode[1:0]=00 -> Link/Act: (On=Link, Off=no Link, Flash=Tx or
Rx activity)
CPU Controlled LED.
On=Corresponding register 1
Off=Corresponding register 0
Input Upon Reset = Refer to Table 9, on page 27, and Table 10, on
page 29.
LED_ADD[4:0]/..
91,
96,
101,
107,
111
I/OPU
4
Output After Reset = Used for Group D LEDs.
RTL8306SD/RTL8306SDM controlling LED:
LEDMode[1:0]=11 -> Link/Act/Spd: On for link established. Blinking
every 43ms when the corresponding port is transmitting or receiving at
100Mbps. Blinking every 120ms when the port is transmitting or
receiving at 10Mbps.
LEDMode[1:0]=10 -> Bi-color Link/Active: polarity depends on Spd
status.
LEDMode[1:0]=01 -> Link: (On=Link, Off=No Link)
LEDMode[1:0]=00 -> LEDMode[1:0]=00 -> Duplex: (On=Full,
Off=Half)
CPU Controlled LED.
For Single-color LED,
On=Corresponding register 1
Off=Corresponding register 0
For Bi-color LED, displays also depend on pin LED_SPD status.
Input Upon Reset = Refer to Table 9, on page 27, and Table 10, on
page 29.
