Description
100Base-FX Asymmetric Flow control capability (default =0).
Forces the asymmetric flow control capability of Reg.4.11 and
Reg.5.11 upon power-on reset.
1: Asymmetric flow control ability in 100Base-FX
0: No asymmetric flow control ability in 100Base-FX
Note: RTL8208BF-LF only.
FX_DUPLEX: Force 100Base-FX Full Duplex Mode (default =1).
This pin sets 100Base-FX duplex and affects those ports in
100Base-FX mode.
1: Full duplex
0: Half duplex
Upon reset, this pin sets the default values of Reg.0.8 of those ports in
100Base-FX.
Note: RTL8208BF-LF only.
Enable Auto Crossover Detection (default =1).
1: Enable auto crossover detection
0: Disable auto crossover detection
Disable power-on/reset LED blinking: (default = 0)
1: Disable power-on LED blinking
0: Blink
LED Blink Time (default =1).
Controls the blinking speed of activity and collision LEDs.
1: 43ms (recommended to use external 10K pull up resistor)
0: 120ms
LED Selection (default=1’b0).

LEDMODE[1:0] (default = 00).
When using the RTL8208B(F)-LF LED solution , we recommend using
an external resister to pull high or pull low.
In Serial LED, LEDMODE[1:0] controls the forms of serial LED status.
