Introduction

AXEL ULite system-on-module (SOM for short) has an internal ethernet PHY connected to the enet1 MAC port.

On-board Ethernet PHY (Micrel KSZ8091RNA) provides interface signals required to implement the 10/100 Mbps Ethernet port. The transceiver is connected to the Ethernet MAC (ENET module) through RMII interface.

The following table describes the interface signals:

Pin Pin name Internal connection Ball/pin # Notes
J2.13 ETH_LED1 LAN.LED0/PME_N1 23
J2.19 ETH_TX_P LAN.TXP 6
J2.21 ETH_TX_M LAN.TXM 5
J2.23 ETH_RX_P LAN.RXP 4
J2.25 ETH_RX_M LAN.RXM 3
J2.31 SNVS_TAMPER2 CPU.SNVS_TAMPER2 P11 PHY INT
