Differential receive pair.
Differential data is received from the media.
Differential Pseudo ECL signal is received from the media in fiber mode.
Differential transmit pair.
Differential data is transmitted to the media in TP mode.
Differential Pseudo ECL signal transmits to the media in fiber mode.
Fiber-optic signal detect
PECL signal which indicates whether or not the fiber-optic receive pair is
receiving valid signal levels.
Full/Half Duplex LED
Active states indicate the full-duplex mode. Active states see LED
configuration
Full-Duplex/Collision LED: when bit 5 of register 16 is set high
Active states indicate the full-duplex mode or activity Collision LED when
in the half-duplex mode. Active states see LED configuration
OP0: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161 according to the Table A. The value is latched into the DM9161
registers at power-up/reset
Speed LED
Active states indicate the 100Mbps mode. Active states see LED
configuration
When bit 6 of Register 16 is set high, it controls the SPEED LED as
100Base-TX SD signal output. For debug only
OP1: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161 according to the Table A. The value is latched into the DM9161
registers at power-up/reset
Link LED & Activity LED:
Active states indicate the good link for 10Mbps and 100Mbps operations.
It is also an active LED function when transmitting or receiving data.
Active states see LED configuration
OP2: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161 according to the Table A. The value is latched into the DM9161
registers at power-up/reset
