Description
O IDSEL2
When this pin pull-high, the PCI multiple function is present.
And this pin act as PCI IDSEL 2 function.
O GNT2# or LED Mode
The DM9102H is in LED mode 1 when this pin is pulled high;
otherwise the mode 0 is selected.
When pin 75 is pull-high, the PCI multiple functions are present.
And this pin act as PCI GNT2# function.
I REQ2#
When pin 75 is pull-high, the PCI multiple functions are present.
And this pin act as PCI REQ2# function.
O LED Output Pin, Active Low
mode 0 = Link and traffic LED. Active low to indicate normal
link and it will flash as traffic LED when transmitting or receiving.
mode 1 = traffic LED only
O LED Output Pin, Active Low
mode 0 = Full duplex LED
mode 1 = Full duplex LED
O LED Output Pin, Active Low
mode 0 = 100Mbps LED
mode 1 = 100Mbps LED
O LED Output Pin, Active Low
mode 0 = 10Mbps LED
mode 1 = Link LED

Description
I 100M/10Mbps Differential Input Pair.
These two pins are differential receive input pair for
100BASE-TX and 10BASE-T. They are capable of receiving
100BASE-TX MLT-3 or 10BASE-T Manchester encoded
data.
O 100M/10Mbps differential output pair.
These two pins are differential output pair for 100BASE-TX
and 10BASE-T. This output pair provides controlled rising and
falling time, designed to filter the transmitter’s output.
