Function
PORT0 Link & Active LED/Link LED.
If LEDMODE_0 is 1, this pin indicates both link status and RX/TX
activity. When link status is LINK_UP, LNKACT_0 will be turned
on. While PORT0 is receiving/transmitting data, LNKACT_0 will
be off for 100ms and then on for 100ms.
If LEDMODE_0 is 0, this pin only indicates RX/TX activity.
Port0 LED DATA
LED mode for LINK/ACT LED of PORT0.
During power on reset, value will be latched by ADM6993/X at the
rising edge of RESETL as LEDMODE_0.
PORT1 Link & Active LED/Link LED.
If LEDMODE_2 is 1, this pin indicates both link status and RX/TX
activity. When link status is LINK_UP, LNKACT_1 will be turned
on. While PORT1 is receiving/transmitting data, LNKACT_1 will
be off for 100ms and then on for 100ms.
If LEDMODE_2 is 0, this pin only indicates RX/TX activity.
Port1 LED DATA
LED mode DUPLEX/COL LED of PORT0 & PORT1.
During power on reset, value will be latched by ADM6993/X at the
rising edge of RESETL as LEDMODE_1.
If LEDMODE_1 is 1, DUPCOL[1:0] will display both duplex
condition and collision status.
If LEDMODE_1 is 0, only collision status will be displayed.
LED mode for LINK/ACT LED of PORT1

PORT0 Duplex LED
If LEDMODE_1 is 1, this pin indicates both duplex condition and
collision status. When FULL_DUPLEX, this pin will be turned on
for PORT0. When HALF_DUPLEX and no collision occurs, this
pin will be turned off. When HALF_DUPLEX and a collision
occurs, this pin will be off for 100ms and then on for 100ms.
If LEDMODE_1 is 0, this pin indicates collision status. When in
HALF_DUPLEX and a collision occurs, this pin will be off for
100ms and turn on for 100ms.
Port0 Collision LED
Disable Address Learning.
During power on reset, value will be latched by ADM6993/X at the
rising edge of RESETL as DIS_LEARN. If DIS_LEARN is 1, MAC
address learning will be disabled.
