Description

104

LNK1_LED

Port 1 Link / Active LED

It is the combined LED of link and carrier sense signal

of the internal PHY1

105

SPD1_LED

Port 1 Speed LED

Its low output indicates that the internal PHY1 is

operated in 100M/S, or it is floating for the 10M mode of

the internal PHY1

106

FDX1_LED

Port 1 Full-duplex LED

Its low output indicates that the internal PHY1 is

operated in full-duplex mode, or it is floating for the

half-duplex mode of the internal PHY1

107

LNK0_LED

Port 0 Link / Active LED

It is the combined LED of link and carrier sense signal

of the internal PHY0

108

SPD0_LED

Port 0 Speed LED

Its low output indicates that the internal PHY0 is

operated in 100M/S, or it is floating for the 10M mode of

the internal PHY0

109

FDX0_LED

Port 0 Full-duplex LED

Its low output indicates that the internal PHY0 is

operated in full-duplex mode, or it is floating for the

half-duplex mode of the internal PHY0
