Miscellaneous
RMII is the factory default mode.
To evaluate the MII mode, the user has to unsolder R49, R50, R127 and close S7 and
S8.
When the RMII mode is used, the user can use the specific MII signals as PIO, but the
following resistors must be unsoldered (R119 to R126).
Refer to the TOP level schematic for the PIO usage.
