An example program is included in the EZ-Board installation directory to
demonstrate how to set up and access the rotary encoder interface.

Ethernet Interface

The ADSP-BF526 processor has an integrated Ethernet MAC with media
independent interface (MII) and reduced media independent interface
(RMII), which connects to an external PHY. The EZ-Board provides a
SMSC LAN8700 RMII Ethernet PHY with Auto-MDIX, fully compliant
with IEEE 802.2/802.2u standards. The SMSC LAN8700 chip supports
10BASE-T and 100BASE-TX operations. The part is attached gluelessly
to the processor.
The Ethernet signals are shared with NAND flash; by default, the Ether-
net mode is set

It is important not to run code that accesses NAND flash while
using the Ethernet interface.
The Ethernet mode is set by the

The Ethernet chip is pre-loaded with a MAC address. The MAC address
for the EZ-Board is stored in the configuration flash section of the parallel
flash memory and can be found on a sticker on the bottom side of the
board.
