Description
LED_ADD[2]/
SetGroup
Input upon reset = Set group of port 1
:
1: Port 0 is group X. Port 1, 2, and 3 are group Y
0: Port 0, and 1 are group X. Port 2, and 3 are group Y
LED_ADD[3]/
GxMode
Input upon reset = Group X operating mode
:
1: UTP mode
0: FX mode
LED_ADD[4]
/GyMode
Input upon reset = Group Y operating mode
:
1: UTP mode
0: FX mode
LED_DUP[0]/
P4ANEG
Input upon reset = Port4 Auto-Negotiation ability
:
1: Enable auto-negotiation (NWAY mode)
0: Disable auto-negotiation (Force mode)
Upon reset, this pin sets Reg.0.12 of Port4. Strap after reset for initial
value of Port4 UTP mode only. This pin is not used for Port4 FX, MAC
mode MII, PHY mode MII, and PHY mode SNI.
LED_ACT[0]/
GxANEG
Input upon reset = GroupX Auto-Negotiation ability
:
1: Enable auto-negotiation (NWAY mode)
0: Disable auto-negotiation (Force mode)
Upon reset, this pin sets Reg.0. 12 of Group X. Strap after reset for initial
value of UTP mode only. This pin is not used for FX.
LED_SPD[0]
/GyANEG
Input upon reset = GroupY Auto-Negotiation ability
:
1: Enable auto-negotiation(NWAY mode)
0: Disable auto-negotiation (Force mode)
Upon reset, this pin sets Reg.0. 12 of Group Y. Strap after reset for initial
value of UTP mode only. This pin is not used for FX.
LED_DUP[1]
/GxSpd100
GxSpd100=1, GxFull=1
=> MII Reg0.13=1, 0.8=1, 4.8=1, 4.7=1, 4.6=1, 4.5=1
GxSpd100=1, GxFull=0
=> MII Reg0.13=1, 0.8=0, 4.8=0, 4.7=1, 4.6=1, 4.5=1
GxSpd100=0, GxFull=1;
=> MII Reg0.13=0, 0.8=1, 4.8=0, 4.7=0, 4.6=1, 4.5=1
GxSpd100=0, GxFull=0;
=> MII Reg0.13=0, 0.8=0, 4.8=0, 4.7=0, 4.6=0, 4.5=1
Upon reset, this pin sets Reg.0.13. In addition, upon reset, this pin and
GxFull also sets Reg.4.8/4.7/4.6/4.5. Strap after reset for initial value of
Group X UTP mode only. This pin is not used for FX.
