TJA1100 RMII mode

[shinichitakko]

Hi,

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).

Hi,

the best way is to use pin strapping:

There are no other settings needed (related to selection of the RMII).

Regards,

Lukas
