Description
Select 10/100BaseTX or 100BaseFX:
(default = 2’b00)
If RPT_MODE = 0:
2’b00: All 8 ports (port0~port7) are 10Base-T/100Base-TX.
2’b01: Port 7 is 100FX, other ports are 10Base-T/100Base-TX.
2’b10: Ports 6 & 7 are 100FX, other ports are 10Base-T/100Base-TX.
2’b11: All 8 ports are 100Base-FX.
If RPT_MODE =1:
2’b00: All 8 ports (port0~port7) are 10Base-T/100Base-TX.
2’b01: Port 7 and 5 are 100FX, others are 10Base-T/100Base-TX.
2’b10: Ports 1,3,5&7 are 100FX, others are 10Base-T/100Base-TX.
2’b11: All 8 ports are 100Base-FX.
Port Pair Loop Back mode:
(default =0)
Upon power-on reset, this pin is input to assert PP-LPBK mode. When
set, all eight ports are port-pair looped back, acting like a signal
regeneration/transformation repeater.
Refer to the section covering PP-LPBK mode.
PHY Address:
(default = 2’b01) These 2bits determine the highest
2bits of 5-bit PHY address upon reset.
Select RMII/SMII/SS-SMII mode:
(default = 2’b11)
2’b1x: RMII
2’b00: SMII
2’b01: SS-SMII
Twisted Pair Pause capability:
(default =1) Sets the Flow control
ability of Reg.4.10 for UTP ports upon power-on reset.
1: With flow control ability.
0: Without flow control ability
100Base-FX Flow control capability:
(default =1)
Forces the flow
control capability of Reg.4.10 and Reg.5.10 upon power-on reset.
1: With flow control ability in 100Base-FX.
0: Without flow control ability in 100Base-FX.
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.
Disable power-on reset LEDs blinking:
(default = 0)
1=Disable power-on LED blinking
0=blink.
LED blink time:
(default =1) Used to control blinking speed of
activity and collision LEDs.
1= 43ms
0= 120ms
LEDMODE[1:0]:
(default = 00) Controls the forms of serial LED status.
LEDMODE Mode Output
2’b00
3-bit serial stream
Col/Fulldup, Link/Act, Spd
2’b01
2-bit serial stream Spd, Link/Act
2’b10
3-bit for Bi-color LED Col/Fulldup, Link/Act, Spd
