Network Indicator LED Signals Symbol Type Pin No. Description /LINKLED O J2:3 Link LED It indicates the link status of media(10/100M). /TXLED O J2:4 Transmit activity LED : Transmit Enable It notifies the output of transmit data through TXOP/TXON (Transmit Activity). /RXLED O J2:5 Receive activity LED : Transmit Data It notifies the input of receive data from RXIP/RXIN (Receive Activity) /COLLED O J2:6 Collision LED : Transmit Data It notifies when collisions occur. It is valid at half-duplex, and is ignored at full-duplex. /FDXLED O J2:7 Full duplex LED : Transmit Data It outputs low at the full-duplex and outputs high at the halfduplex according to auto-negotiation or manual configuration of OP_MODE[2:0]. /SPDLED O J2:8 Link speed LED : Transmit Data It is asserted low at the 100Mbps and high at the 10Mbps according to auto-negotiation or manual configuration of OP_MODE[2:0]. /ACTLED O J2:9 Activity LED It notifies the output of transmit data through TXOP/TXON or the input of receive data from RXIP/RXIN. 2.5. Miscellaneous Signals Symbol Type Pin No. Description /RESET I J2:17 Reset : This pin is active low input to initialize or re-initialize W5300. RESET should be held at least 2us after low assert, and wait for at least 10ms after high de-assert in order for PLL logic to be stable BRDY[3:0] O J2:11 ~ J2:14 Buffer Ready Indicator BRDYn monitors TX/RX memory status of each socket.
