The MODE[2:0] hardware configuration pins are multiplexed with other signals as shown in
RMIISEL: MII/RMII Mode Configuration
MII or RMII mode selection is latched on the rising edge of the internal reset (nRST) based on the
strapping of the RMIISEL configuration strap. The default mode is MII (via the internal pull-down
resistor). To select RMII mode, pull the RMIISEL configuration strap high with an external resistor to
VDDIO.
When the nRST pin is deasserted, the
