Function
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.
LED mode for LINK/ACT LED of PORT0 & PORT1.
During power on reset, value will be latched by NINJA C/CX
(ADM6992C/CX) 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.
PORT0 Duplex/Collision 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.
Collision LED
Disable Address Learning.
During power on reset, value will be latched by NINJA C/CX
(ADM6992C/CX) at the rising edge of RESETL as DIS_LEARN.
If DIS_LEARN is 1, MAC address learning will be disabled.
PORT1 Duplex
If LEDMODE_1 is 1, this pin indicates both duplex condition and
collision status. When FULL_DUPLEX, this pin will be turned on
for PORT1. 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
HALF_DUPLEX and a collision occurs, this pin will be off for
100ms and turn on for 100ms.
Collision LED
PORT0 Speed LED
Used to indicate speed status of PORT0. When operating in
100Mbps this pin is turned on, and when operating in 10Mbps this
pin is off.
FXMODE0
During power on reset, value will be latched by NINJA C/CX
(ADM6992C/CX) at the rising edge of RESETL as bit 0 of
FXMODE.
