4.1 Ethernet

The MSP432E411Y-BGAEVM development kit can connect directly to an Ethernet network using RJ45 connectors. The microcontroller contains a fully integrated Ethernet MAC and PHY. This integration creates a simple, elegant, and cost-saving Ethernet circuit design. Example code is available for the lwIP TCP/IP protocol stack. The embedded Ethernet on this device can be programmed to act as an HTTP server, a client, or both. The design and integration of the circuit and microcontroller can also synchronize events over the network using the IEEE 1588 precision time protocol. The existing SimpleLink SDK network stack includes an example of using this feature.

The Ethernet jack on the EVM contains two LEDs, one green and one yellow, that are controlled by pins PN0 and PN1 on the MSP432E411Y. When configured for Ethernet operation, the application should control these pins directly, because the PHY-controlled LED pins have not been provided for LED function.
