Pin No.
Collision LED : Active low when collisions occur.
Link 100/ACT LED : Active low when linked by 100 Base TX,
and blinking when transmitting or receiving data.
Link 10/ACT LED : Active low when linked by 10 Base T, and
blinking when transmitting or receiving data.
Full Duplex LED : Active low when in full duplex operation.
Active high when in half duplex operation.
Link LED : Active low when linked
Interrupt : Active low
After reception or transmission it indicates that the
W3100A-LF requires MCU attention.
By writing values to the Interrupt Status Register of
W3100A-LF the interrupt will be cleared.
All interrupts can be masked by writing values to the
IMR of W3100A-LF(Interrupt Mask Register).
