3.3V power for the DP83848K MAU may be supplied via MII connector. If 3.3V is supplied
from the MII connector. R32 needs to be stuffed (See schematics for details)
External 3.3V power is supplied for the DP83848K MAU, if 5V is supplied from the MII
connector. R32 should not be stuffed in this case (See schematics for details)
To set Auto-MDIX ON, do not stuff resistor R30. To set Auto-MDIX OFF, stuff resistor R30
(See schematics for details)
To configure LED in mode1 for link, do not stuff resistor R31. To configure LED for link and
activity, stuff resistor R31 (See schematics for details)
If the DP83848K MAU card is used for a PHYTERMini device – DP83848M/T/H, remove
resistor R42 (See schematics for details)
Default board setting for the PHY Address is 01 (Do not stuff resistor R29)
The board may be set to PHY Address 03 by stuffing resistor R29.
