Please tell me about RMII register settings of TJA1100 PHY.Is it OK to set "MII_MODE" of "Configuration register 1" from the default setting "00" to "01"? Is there any other setting?50 MHz is connected to REF_CLK(pin25).
the best way is to use pin strapping:
There are no other settings needed (related to selection of the RMII).
