ETHERNET Configuration
RMII is the factory default mode.
To evaluate the MII mode, the user has to unsolder R92 and solder R93, R98 to R104, R107.
Two types of jumpers are used on the SAM9M10-EKES board:
2-pin jumpers with two possible settings:
– Fitted: the circuit is closed, and
– Not fitted: the circuit is open
3-pin jumpers with two possible positions, for which settings are presented in the following tables.
