C Interface
The DM355 EVM incorporates an ethernet controller chip. This interface is connected
to the DM355’s EMIF. The EVM uses an Intel DAVICOM DM9000A. The 10/100 Mbit
interface is isolated and brought out to a RJ-45 standard ethernet connector, P5. The
ethernet address is stored in the ethernet controller’s SPI ROM during manufacturing.
The RJ-45 has 2 LEDs integrated into its connector. The LEDs are green and yellow
and indicate the status of the ethernet link. The green LED, when on, indicates link and
when blinking indicates link activity. The yellow LED, when illuminated, indicates full
duplex mode.
